CHANGELOG.md

7.1.0

• Many dependency updates and cleanups (ember-concurrency 3.0, ember 4.12, drop node 14...) #705

7.0.2

• Improve typescript expertience for users using exactOptionalPropertyTypes and noImplicitOverride

7.0.1

• Receive @animationEnabled in the content component.

7.0.0

• Update ember-maybe-in-element for version that plays nicely with parallel compilation.
• [BREAKING] Update many dependencies, including qunit and ember-auto-import v2. Now the minimum version is 3.28+

6.0.2

• Relax dependency on ember-style-modifier so version 1.0 is also allowed

6.0.1

• Allow ember-get-config v2

6.0.0

• [MAYBE-BREAKING] The trigger component is now implemented internally as an element modifier. This should not be breaking, but a refactor this big is always risky. This makes much easier to make any component the trigger of a dropdown, just applying that modifier to any element.
• Because of the element modifier change, not the minimum version of Ember supported is 3.24

5.0.0

• [BREAKING] Co-locate component templates. This is breaking for anyone overriding the component's templates with their own, as the location of the template has changed.
• Typescript fix for configuration.

4.0.4

• [FEATURE] Improve compatibility with Embroider/Ember 4

4.0.3

• Fix animation when component is not rendered in place.

4.0.2

• Update dependency in @ember/render-modifiers to 2.0.2 with fixes a bug with unnecessary recomputations.

4.0.1

• (#628) Fix issue, The @animationClass class don't get reset after the first render. When the dropdown content first renders, it animates correctly, but on subsequent renders there is no animation - cause @animationClass not being reset back to transitioning--in state.

4.0.0

• (#633) A11y improvements, changing aria-controls instead of aria-owns, which seems to be more correct.
• [BREAKING] Stop using a polyfill for Object.assign, which effectively removes support for Internet Exporer. But it's 2022, its about time.

3.0.19

• Update ember-element-helper to fix issues with CI.

3.0.18

• Relax dependencies on embroider packages

3.0.17

• Import htmlSafe from @ember/template to fix deprecation warning.
• Migrate to github actions and fix stuff to make CI green again.

3.0.13

• Use ember-style-modifier in one more place.
• Migrate to github actions and fix CI on beta and canary. This was done by relaxing a dependency on the embroider utils.

3.0.12

• Use ember-style-modifier for setting styles on element instead of using inline styles. This allows to use the addon on webs that forbid inline styles on they CSP config.

3.0.11

• Relax dependency on ember-truth-helpers

3.0.10

• More IE11 fixes.

3.0.9

• Use assign polyfill for IE11 support.

3.0.8

• Update ember-maybe-in-element to 2.0.1, which fixes deprecation about {{-in-element}} usage.

3.0.7

• Add back onXXX event handlers to the trigger and content components, removed in the transition to angle bracket components, because make some patterns easier as it allows to set handlers to those events when defining the contextual component, instead of in invocation time

3.0.6

• [BUGFIX] Restore ability to change horizontalPosition and verticalPosition after initialization, lost at some point in the transition to glimmer components.

3.0.5

• TS: Fix type definition: Allow touch events in handleRootMouseDown on another location.

3.0.4

• TS: Fix type definition: Allow touch events in handleRootMouseDown.

3.0.3

• A11y fix: When the component is not expanded, it must have aria-expanded="false".

3.0.2

• Ensure this._super in invoked in the included hooks.

3.0.0-beta.8

• [BUGFIX] Ensure the otherStyles is initialized with a copied object.

3.0.0-beta.7

• [CHORE] Update to @glimmer/component 1.0.0
• [BUGFIX] If there's no enough space for the dropdown above nor below the trigger, put it below.

3.0.0-beta.6

• [CHORE] Improve exported types

3.0.0-beta.5

• [BUGFIX] Don't use typescript in /app folder

3.0.0-beta.4

• [CHORE] Convert to typescript

3.0.0-beta.3

• [BUGFIX] Fix reposition of dropdown after scroll or window resize events

3.0.0-beta.2

• [CHORE] Update to @glimmer/component 1.0.0-beta.2

3.0.0-beta.1

• No changes since alpha 1

3.0.0-alpha.1

• [MAYBE-BREAKING] Update to glimmer components

2.0.10

• [BUGFIX] Use set when changing previousVerticalPosition and previousHorizontalPosition.

2.0.9

• [CHORE] Update some dependencies. More importantly ember-element-modifiers to 1.0.2 which changes its behavior.

2.0.8

• [BUGFIX] Correct condition in which the development assertion added in 2.0.6 is thrown. Logic was reversed.

2.0.7

• [BUGFIX] Update ember-element-helper to 0.2.0 to fix bug in engines

2.0.6

• [ENHANCEMENT] Add development assertion to help people understand the somewhat cryptic error message that appeared when there was no element with id ember-basic-dropdown-wormhole in the document

2.0.5

• [CHORE] Update npm packages to tests pass in beta and canary
• [BUGFIX] Ensure Ember doesn't complain about not using set to update values.

2.0.4

• [ENHANCEMENT] Allow to pass a @defaultClass argument to the content. This is necessary to be able to assign classes while the {{component}} helper does not allow to pass attributes like in angle-bracket syntax.

2.0.3

• [ENHANCEMENT] Allow to pass a @defaultClass argument to the trigger. This is necessary to be able to assign classes while the {{component}} helper does not allow to pass attributes like in angle-bracket syntax.

2.0.2

• [BUGFIX] Move ember-truth-helpers to dependencies.

2.0.1

• [ENHANCEMENT] Expose ember-basic-dropdown/utils/calculate-position as public API.

2.0.0

• [CHORE] Setup/teardown mutation observer using dedicated element modifiers.
• [CHORE] Refactor animation logic to use {{did-insert}}/{{will-destroy}} element modifiers.

2.0.0-beta.3

• [BREAKING] Remove onMouseDown,onClick,onKeyDown and onTouchEnd attributes from the <dropdown.Trigger> component. Users can just use the {{on}} modifier to attach events now, although that means that to prevent the default event handler from being called for those events, instead of return false, they must call event.stopImmediatePropagation() like they would with regular events.

2.0.0-beta.2

• [BREAKING] Remove onMouseEnter,onMouseLeave,onFocus,onBlur,onFocusIn,onFocusOut and onKeyUp from the <dropdown.Trigger> component. Users can just use the {{on}} modifier to attach any event they want.
• [BREAKING] Remove onFocusIn, onFocusOut, onMouseEnter, onMouseLeave and onKeyDown from the <dropdown.Content> component. Users can just use the {{on}} modifier to attach any event they want.

2.0.0-beta.1

• [CHORE] Now that Ember 3.11 is released, this can go to beta.

2.0.0-alpha.X

• Because of some limitation of splattributes in AngleBracket components, the addons requires Ember 3.11+
• Public API changed: Previously the contextual component of this addon were invoked with {{#dd.trigger}} and {{#dd.content}}. Now they are expected to be invoked with <dd.Trigger> and <dd.Content>. Note that the names are capitalized. This is done because the new convention that components start with a capital letter.
• Passing @class, @defaultClass, aria-* and most of those properties doesn't work anymore. This addon now expects to be used with angle-bracket syntax. In angle bracket syntax there is a distinction between component arguments (those preceded with an @ sign) and html attributes, and the latter are a much better way of passing any arbitrary attribute to any of the components and sub-components of this addon.
• The default eventType of the trigger changed from "mousedown" to "click". That means that dropdown used to open with the mousedown events will now open with click events, which is a saner default. Since most of the time those events are fired together most people won't notice any difference, but in testing if someone was explicitly firing mouseodown events tests would have to be updated.
• The default rootEventType has changed from "mousedown" to "click". That means that before dropdowns would close as soon as the user mousedowns outside the dropdown, but not it will listed to click events by default. It's unlikely this change will be noticed by anyone.

1.1.2

• [ENHANCEMENT] Allow to bind the type attribute of the trigger.

1.1.1

• [ENHANCEMENT] Allow to customize the root event the component listens to in order to close when you click outside it. It has historically been mousedown, but now it can be click. This allows to scroll the page using a scrollbar. In a future version click will become the default.

1.1.0

• [REAPPLY] Revert the revert in 1.0.6. Technically identical to 1.0.5

1.0.6

• [REVERT] Revert change in 1.0.5 as it is a breaking change for Ember Power Select. Will fix EPS and apply again.

1.0.5

• [BUGFIX] A11y improvement: The trigger doesn't have an aria-owns attribute until the dropdown is open, because it's illegal for an aria-owns to reference an element (the content) that it's not in the page (yet).

1.0.4

• [BUGFIX] Fix code to find the destination element in fastboot.

1.0.3

• [FEATURE] Allow onKeyUp action to added to the trigger.

1.0.2

• [FEATURE] Allow onKeyDown action to the content component

1.0.1

• [DOCS] Document eventType option that has existed for a while now.
• [FEATURE] Add stopPropagation option to the trigger to prevent the propagation of the event

1.0.0

• NO NEW CHANGES, just version 1.0. It was about time.

1.0.0-beta.8

• [CLEANUP] Remove another reduntad self. prefix.

1.0.0-beta.7

• [CLEANUP] Remove unnecessary self. prefix to access a few globals like document or window.

1.0.0-beta.6

• [CLEANUP] Remove passing to="id-of-destination" that has been deprecated for a long time.

1.0.0-beta.5

• [BUGFIX] Fix event being fired on destroyed trigger in Ember 3.2 and beyond.

1.0.0-beta.4

• [FEATURE] Allow dropdowns with a custom calculatePosition function to return in the styles object css properties other than top, left, right, height and width. Now users can set any arbitrary properties. P.e. max-height, z-index, transform....

1.0.0-beta.3

• [INTERNAL] Stop depending internally on ember-native-dom-helpers. Now the utilities in ember-test-helpers have been ported to @ember/test-helpers, so they are not needed anymore.

1.0.0-beta.0

• [DEPRECATION] Deprecate global acceptance helpers clickDropdown and tapDropdown. Suggest to explicitly import clickTrigger/tapTrigger or even better, just use click/tap from @ember/test-helpers.
• [BREAKING] Drop ember-wormhole addon, use #-in-element built-in instead. Less size, more performance.
• [BREAKING] Drop support for Ember <= 2.9. This addon will require Ember 2.10 or greater to work.

0.34.0

• [BREAKING] Delete the /test-support folder, use addon-test-support instead. That means people should import helpers from ember-basic-dropdown/test-support/helpers instead of using relative paths like ../../helpers/ember-basic-dropdown, as they are brittle and change with nesting.
• [BUGFIX] Ensure that the dropdown is not open by the right button of the mouse.

0.33.10

• [ENHANCEMENT] Allow horizontalPosition to work when renderInPlace=true

0.33.9

• [ENHANCEMENT] Allow to bind the role attribute of the trigger
• [ENHANCEMENT] Added preventScroll=true option to the dropdown.content component to "frezze" all mousewheel-triggered scrolling happening outside the component. Scrolling on touch devices using touchmove can still occur.

0.33.7

• [ENHANCEMENT] Enable renderInPlace=true dropdowns to be dynamically repositioned. (#350)
• [BUGFIX] Ensure the inline style attribute does not output undefinedpx when some style is undefined. Also, ensure that both left and right cannot be applied simultaneous, as it doesn't make sense.

0.33.6

• [BUGFIX] Prevent dropdowns with renderInPlace=true from being incorrectly opened twice. This had no evident effects, but lead to the events in the dd.Content component to be added twice.
• [BREAKING] Remove support for IE9/IE10.

0.33.5

• [ENHANCEMENT] Allow transitioningInClass and transitioningOutClass to be several classes by passing a string with spaces in it.

0.33.4

• [BUGFIX] Allow to use horizontalPosition="center" along with renderInPlace=true.

0.33.3

• [BUGFIX] When the component is rendered in-place, it still has to have the --below class needed. While not used for positioning, it was used for animations.

0.33.2

• [BUGFIX] Fix positioning problem when the body has position relative.

0.33.1

• [BUGFIX] Move test helpers to /addon-test-support and use /test-support only for reexporting so apps don't require babel 6.6.0+ to work.

0.33.0

• [INTERNAL] Stop relying in Ember.testing to decide the wormhole destination. Not just uses the environment.
• [ENHANCEMENT] This component by default opens with mousedown events, not with click. This behavior has its reasons but it's also surprising for some users and it might not be adequate sometimes. Now the trigger accepts an eventType="mousedown" | "click" (defaults to "mousedown" as today). This doesn't affect touch devices, as those are opened/closed with the touchend event.
• [INTERNAL] Use the new import paths (e.g: import Component from '@ember/component)

0.32.9

• [ENHANCEMENT] Add auto-right option for horizontal position. It's like auto, but it defaults to being anchored to the right unless there is not enough room towards the left for the content.

0.32.8

• [ENHANCEMENT] Update ember-native-dom-helpers to ^0.5.0.

0.32.7

• [BUGFIX] Guard agains edge case where positioning could fail if the select close and opened extremely fast

0.32.6

• [BUGFIX] Add global events to the document instead of the body, so the dropdown works even if the body is smaller than the height of the window

0.32.5

• [ENHANCEMENT] Update ember-native-dom-helpers to 0.4.0

0.32.4

• [BUGFIX] Fix broken render in place after refactor for allowing dropdowns in scrollable elements.

0.32.3

• [ENHANCEMENTE] Allow to nest dropdowns infinitely. Thanks to @alexander-alvarez

0.32.2

• [BUGFIX] Stop looking for scrollable ancestors on the BODY or HTML

0.32.1

• [BUGFIX] Allow to work if the container has no offsetParent. This happens if the body is relative.

0.32.0

• No changes in previous beta

0.32.0-beta.0

• [ENHANCEMENT] Dropdowns inside elements with their own scroll are finally supported! It works even inside elements with scroll inside another element with scroll inside pages with scroll.
• [BREAKING/BUGFIX] Closes #233. The positioning logic now accounts for the position of the parent of container if it has position relative or absolute. The breaking part is that custom calculatePosition functions now take the destination element as third arguments, and the object with the options has now been moved to thr forth position.
• [BREAKING] Passing to="id-of-elmnt" to the {{#dropdown.content}} component is deprecated. The way to specify a different destination for ember-wormhole is now by passing destination=id-of-elmnt to the top-level {{#basic-dropdown}} component. The old method works but shows a deprecation message.

0.31.5

• [INTERNAL] Update ember-concurrency to a version that uses babel 6.

0.31.4

• [BUGFIX] Fix calculation of the screen's width when browser shows a scrollbar, which affected dropdowns with horizontalPosition="right".
• [BUGFIX] Fix initial CSS positioning flickering caused by refactor that removed jQuery.

0.31.2

• Now the addon is 100% jQuery-free. Docs page doesn't use jQuery either. Tests in CI run without jquery so if anyone inadvertenly relies on it, tests will fail.
• Rewrite tests to use async/await with the latest ember-native-dom-helpers

0.31.1

• Update to ember-native-dom-helpers 0.3.4, which contains a new & simpler import path.

0.31.0

• [INTERNAL/BREAKING???] Update to Babel 6. This shouldn't be breaking, but you never know.

0.30.3

• [BUFGIX] Fix unnecesary line break caused by the wormhole empty div. Solved by making that div be display: inline.

0.30.1

• [ENHANCEMENT] Allow the calculatePosition function to also determine the height of the dropdown's content.

0.30.0

• [BREAKING] Unify calculatePosition and calculateInPlacePosition. Now the function receives an renderInPlace flag among its options, and based on that it uses a different logic. This reduces the public API surface. This new function is the default export of /utils/calculate-position. The individual functions used to reposition when rendered in the wormhole or in-place are available as named exports: calculateWormholedPosition and calculateInPlacePosition

0.24.5

• [INTERNAL] Use ember-native-dom-helpers.

0.24.4

• [ENHANCEMENT] The trigger component now has a bound style property.

0.24.3

• [ENHANCEMENT] Rely on the new ember-native-dom-helpers to fire native events instead or rolling out my own solution.

0.24.2

• [BUGFIX] Fix synthetic click on the trigger when happens in SVG items.

0.24.1

• [ENHANCEMENT] Bind aria-autocomplete and aria-activedescendant.
• [BUGFIX] Check if the component is destroyed after calling the onClose action, as it might have been removed.

0.24.0

• [BREAKING] It is a problem for a11y to have aria-owns/controls to an element that it's not in the DOM, so now there is a stable div with the right ID that gets moved to the root of the body when the component opens.
• [BUGFIX] Fix clickDropdown test helper when the given selector is already the selector of the trigger.

0.23.0

• [BREAKING] Don't display aria-pressed when the component is opened. The attribute is not present by default, but can be bound from the outside.
• [BREAKING] Don't display aria-haspopup by default, but display it if passed in a truthy value.
• [BREAKING] Use aria-owns instead of aria-controls to link trigger and content together.

0.22.3

• [FEATURE] The dropdown.content now accepts a defaultClass property as a secondary way of adding a class in contextual components that doesn't pollute the class property.

0.22.2

• [FEATURE] clickTrigger test helper also works when the given selector is the one of the trigger (before it had to be an ancestor of the trigger).

0.22.1

• [FEATURE] It accepts an onInit action passed from the outside. Private-ish for now.

0.22.0

• [FEATURE/BREAKING] Allow to customize the ID of the trigger component. Now the dropdown uses a new data-ebd-id attribute for query the trigger reliably. Unlikely to be breaking tho.

0.21.0

• [FEATURE] Add LESS support, on pair with the SASS one.
• [FEATURE] Added $ember-basic-dropdown-overlay-pointer-events SASS variable.

0.20.0

• [BREAKING CHANGE] Renamed onKeydown event to onKeyDown to be consistent with the naming of every other action in the component

0.19.4

• [FEATURE] Allow to pass onMouseDown and onTouchEnd options actions to subscribe to those events. If the handler for those events returns false, the default behaviour (toggle the component) is prevented.

0.19.3

• [FEATURE] Allow to pass onMouseEnter and onMouseLeave actions to the content, like we allow with the trigger.

0.19.2

• [BUGFIX] Prevent the touchend that opens the trigger to trigger a click on the dropdown's content when this appears over the trigger. Copied from hammertime.

0.19.1

• [CLEANUP] Update to ember-cli-sass ^6.0.0 and remove node-sass from dependencies.

0.19.0

• [BUGFIX] Call registerAPI will null on willDestroy to avoid memory leaks.

0.18.1

• [ENHANCEMENT] Pass the dropdown itself as an option to calculatePosition and calculateInPlacePosition, so users have pretty much total freedom on that function.

0.18.0

• [ENHANCEMENT] Allow downdowns rendered in place to be positioned above the trigger, and also to customize how they are positioned.

0.17.4

• [ENHANCEMENT] Update to ember-wormhole 0.5.1, which maximises Glimmer2 compatibility

0.17.3

• [BUGFIX] The fix in 0.17.2 that removed e.preventDefault() cause both touchend and a synthetic mousedown events to be fired, which basically made the component to be opened and immediatly closed in touch devises.

0.17.2

• [BUGFIX] Remove e.preventDefault() that caused inputs inside the trigger to not be focusable in touch screens

0.17.1

• [BUGFIX] The positioning strategy takes into account the horizontal scroll and it's generally smarter.
• [BUGFIX] Fixed bug when a dropdown with horizontalPosition="auto" passed from left to right, it keeped both properties, modifiying its width implicitly.

0.17.0

• [BREAKING] The object returned by calculatePosition now contains the offsets of the dropdown as numbers instead of strings with "px" as unit. This makes easier for people to modify those values in their own functions.

0.16.4

• [ENHANCEMENT] The default calculatePosition method is now inside addon/utils/calculate-position, so users can import it to perhaps reuse some of the logic in their own positioning functions.

0.16.3

• [BUGFIX] Add forgotten uniqueId property to the publicAPI yielded to the block. The publicAPI object passes to actions had it but the one in the block didn't.

0.16.2

• [ENHANCEMENT] Allows to customize how the dropdown is positioned by passing a calculatePosition function.

0.16.1

• [BUGFIX] Remove automatic transition detection. It never worked properly. It's fundamentally flawed. CSS animations are OK tho.

0.16.0

• [TESTING] Ensure the addon is tested in 2.4LTS
• [BUGFIX] Fix bug in versions of ember <= 2.6

0.16.0-beta.6

• [BUGFIX] Remove ember-get-config entirely. It turns that there is a less hacky way of doing this.

0.16.0-beta.5

• [BUGFIX] Update ember-get-config to fix Fastboot compatibility.

0.16.0-beta.4

• [BUGFIX] Guard agains a possible action invocation after the component has been destroyed.

0.16.0-beta.3

• [BUGFIX] Fix broken horizontalPosition="center".

0.16.0-beta.2

• [BUGFIX] Bind title attribute in the trigger.

0.16.0-beta.1

• [BUGFIX] Revert glimmer2 compatibility

0.16.0-beta.0

• [BUGFIX] Compatibility with glimmer2.

0.15.0-beta.6

• [BUGFIX] Fix bug detaching event in IE10.

0.15.0-beta.5

• [BUGFIX] The correct behaviour when a dropdown is disabled or the tabindex is false should be to not have tabindex attribute, not to have a tabindex of -1.

0.15.0-beta.4

• [BUGFIX] Don't import guidFor from the shims.

0.15.0-beta.3

• [BUGFIX] Preventing the default behaviour from an event doesn't prevent the component from doing the usual thing.

0.15.0-beta.2

• [BUGFIX] Fix edge case that made the component leak memory if the component is removed after a mousedown but before the mouseup events of the trigger. This situation probably almost impossible outside testing.

0.15.0-beta.1

• [ENHANCEMENT] The dropdown can have an overlay element if it receives overlay=true.

0.15.0-beta.0

• [BREAKING] dropdown.uniqueId is not a string like ember1234 instead of the number 1234.

0.14.0-beta.1

• [BUGFIX] Consider the scope of the select the entire body, even if the app is rendered inside an specific element.

0.14.0-beta.0

• [BREAKING] Rename the dropdown._id to dropdown.uniqueId and promote it to public API.

0.13.0-beta.6

• [BUGFIX] Make the first reposition faster by applying the styles directly instead of using bindings. This allows the dropdown to have components with autofocus inside without messing with the scroll.

0.13.0-beta.5

• [BUGFIX] Enabling the component after it has been disabled should trigger the registerAPI action.

0.13.0-beta.4

• [BUGFIX] Fix bug when the consumer app has a version of ember-cli-shims older than 0.1.3

0.13.0-beta.3

• [BUGFIX] Stop importing getOwner from the shim, since many people doesn't have shims up to date and it's trolling them.

0.13.0-beta.2

• [BUGFIX] Render more than one component with renderInPlace=true cases an exception and after that mayhem happens.

0.13.0-beta.1

• [BUGFIX] Use requestAnimationFrame to wait one frame before checking if the component is being animated. This makes this component fully compatible with Glimmer 2.

0.13.0-beta.0

• [ENHANCEMENT/BREAKING] Now the publicAPI object received sub-components and passed to actions is immutable. That means that each change in the internal state of this component will generate a new object. This allows userts to get rid of Ember.Observe to use some advanced patterns and makes possible some advanced time-travel debugging.

0.12.0-beta.26

• [ENHANCEMENT] Allow to customize the classes used for animations with transitioningInClass, transitionedInClass and transitioningOutClass.
• [BUGFIX] Property detect space on the right when horizontalPosition="auto" (the default) and position the element anchored to the right of the dropdown if there is no enough space for it to fit.

0.12.0-beta.23

• [BUGFIX] Correctly remove touchmove event on touch ends.
• [BUGFIX] Prevent DOM access in fastboot mode.

0.12.0-beta.22

• [ENHANCEMENT] If the component gets disabled while it's opened, it is closed automatically.

0.12.0-beta.21

• [ENHANCEMENT] Expose clickDropdown and tapDropdown acceptance helpers.
• [BUGFIX] Allow to nest a dropdown inside another dropdown without the second being rendered in place.

0.12.0-beta.20

• [BUGFIX] Apply enter animation after render. Otherwise it take place before the component gains the --above or --below class, which is needed to know how to animate.

0.12.0-beta.19

• [BUGFIX] Allow to property of the content component to be undefined

0.12.0-beta.18

• [BUGFIX] Fix positioning of dropdowns rendered in-place due to a typo

0.12.0-beta.17

• [BUGFIX] Ensure the disabled property of the public API is updated properly

0.12.0-beta.13

• [BUGFIX] Ensure reposition is not applied in destroyed components

0.12.0-beta.12

• [BUGFIX] Fix animations

0.12.0-beta.11

• [INTERNAL] Update ember-cli to 2.6
• [INTERNAL] Update ember-wormhole to 0.4.0 (fastboot support)
• [BUGFIX] Correct behaviour of aria-disabled, aria-expanded, aria-invalid, aria-pressed and aria-required in Ember 2.7+
• [ENHANCEMENT] Allow to customize componets for the trigger and the content, with the triggerComponent and contentComponent properties.
• [BUGFIX] Stop relying in this.elementId, since it is not present in Ember 2.7+ on tagless components.
• [ENHANCEMENT] Add an onBlur action to the trigger
• [BUGFIX] Change repositioning logic so it doesn't sets properties from inside the didInsertElement, which is deprecated and causes a performance penalty.

0.12-beta.6

• [ENHANCEMENT] Although the component is tagless by default, if the user passes renderInPlace=true, a wrapper element with class .ember-basic-dropdown is added to be able to position the content properly.
• [BUGFIX] The reposition function no longer sets any observable state, so it can be called at any time without worring about the runloop and double renders. More performant and fixes a bug when something inside gains the focus faster than the reposition.

0.12-beta.5

• [BUGFIX] Don't focus the trigger again when the dropdown is closed as consecuence of clicking outside it.
• [ENHANCEMENT] Allow to add focusin/out events to the trigger

0.12-beta.4

• [BUGFIX] Ensure that if the trigger receives tabindex=null it still defaults to 0.

0.12-beta.3

• [BUGFIX] Ensure that the aria-controls attribute of the trigger points to the content by default.

0.12-beta.2

• [BUGFIX] Focus the trigger when the component is closed
• [BUGFIX] Allow to attach onFocusIn and onFocusOut event the the dropdown content component.

0.12-beta.1

• [BUGFIX] Around half a docen regressions and changes, including add the proper classes to trigger and content when the component is rendered above/below/right/left/center/in-place. Now those cases are different between trigger and content for better granularity.

0.12-beta.0

• [BREAKING CHANGE] Brand new API
