+
+## Goals
+
+- Adds a new dropdown select control to feathers, for selecting one of a number of options. It is similar to the existing `FeathersListView` (and indeed is implemented using one), it also uses a `FeathersMenuPopup` to show the selection
+when opened.
+- The dropdown scrolls if there are more than `@max_visible` options
+- Adds a helper `caption(...)` function, similar to `label()` which emits `(Text(...) ThemedText)`
+- Adds a `SetSelected` event to the underlying `ListBox` bevy_ui_widgets control, which sets its selected value, similar to how `SetChecked` and `SetSliderValue` work.
+
+### Usage
+
+Inside a `bsn!` macro use FeathersSelect scene entity and give it a number of options which contain the `FeathersListRow` component
+
+```
+(
+  @FeathersSelect {
+      @options: ... a Box<dyn SceneList> set of rows, see feathers_gallery for an example
+      @max_visible: 6,
+  }
+),
+```
