How to allow 1 maxselection on a certain section?

[mattmorz]

I wanted to behave a section as radio buttons?
How to I achieve this?

The option right now only supports a global setting, so you can't do this. You can modify the code to fit your purposes though:

tree-multiselect.js/src/tree-multiselect/tree.js

Lines 401 to 415 in 4db8be7

	if (Util.isInteger(this.params.maxSelections) && this.params.maxSelections > 0) {
	const currentLength = this.keysToAdd.length - this.keysToRemove.length + this.selectedKeys.length;
	if (currentLength > this.params.maxSelections) {
	let lengthToCut = currentLength - this.params.maxSelections;
	let keysToCut = [];
	if (lengthToCut > this.selectedKeys.length) {
	keysToCut.push(...this.selectedKeys);
	lengthToCut -= this.selectedKeys.length;
	keysToCut.push(...(this.keysToAdd.splice(0, lengthToCut)));
	} else {
	keysToCut.push(...this.selectedKeys.slice(0, lengthToCut));
	}
	this.keysToRemove.push(...keysToCut);
	}
	}

This will probably need to be implemented a bit differently.

Oh ok..is there a way to dynamically uncheck a selection/checkbox?
or remove the previously selected>

[patosai]

Not natively, but for now you can get the checkbox element and click it/fire the change event

Yes, I managed to solve it using that method. But, it's ugly. :)
