tree-listbox-mixin.mjs Provides keyboard and mouse interaction to a (possibly nested) list. It is intended for lists with a small number (up to 1000?) of items. Only one item can be selected at a time. Maintenance of the items in the list is not managed here. Styling of the list is not managed here. Expects the tree itself to scroll and not any of its parents. List items must have at least one child which contains the main content of the list item. The following class names apply to list items: - selected: Indicates the currently selected list item. - children: If the list item has descendants. - collapsed: If the list item's descendants are hidden. List items can provide their own twisty element, which will operate when clicked on if given the class name "twisty". If a list item can't be selected it should have the "unselectable" class. @mixin @fires {CustomEvent} collapsed - Fired on a row when it is collapsed. Bubbles. @fires {CustomEvent} expanded - Fired on a row when it is expanded. Bubbles. @fires {CustomEvent} select - Fired when the selection changes. @attribute {"tree"|"listbox"} role - Must be either tree or listbox, depending on the mode of the widget. 18185
