| Implements | IFocusDisplayObject |
Layouts may be, and are highly encouraged to be, virtual, meaning that the List is capable of creating a limited number of item renderers to display a subset of the data provider instead of creating a renderer for every single item. This allows for optimal performance with very large data providers.

isSelectable:BooleanDetermines if an item in the list may be selected.
The default value is true.
public function get isSelectable():Boolean public function set isSelectable(value:Boolean):void| itemRendererFactory | property |
itemRendererFactory:Function
A function called that is expected to return a new item renderer. Has
a higher priority than itemRendererType. Typically, you
would use an itemRendererFactory instead of an
itemRendererType if you wanted to initialize some
properties on each separate item renderer, such as skins.
The function is expected to have the following signature:
function():IListItemRenderer
public function get itemRendererFactory():Function public function set itemRendererFactory(value:Function):voidSee also
| itemRendererName | property |
itemRendererName:StringA name to add to all item renderers in this list. Typically used by a theme to provide different skins to different lists.
public function get itemRendererName():String public function set itemRendererName(value:String):voidSee also
| itemRendererProperties | property |
itemRendererProperties:Object
A set of key/value pairs to be passed down to all of the list's item
renderers. These values are shared by each item renderer, so values
that cannot be shared (such as display objects that need to be added
to the display list) should be passed to the item renderers using an
itemRendererFactory or with a theme.
If the subcomponent has its own subcomponents, their properties
can be set too, using attribute @ notation. For example,
to set the skin on the thumb of a SimpleScrollBar
which is in a Scroller which is in a List,
you can use the following syntax:
list.scrollerProperties.@verticalScrollBarProperties.@thumbProperties.defaultSkin = new Image(texture);

The pending item index to scroll to after validating. A value of

starling.events.Eventfeathers.events.FeathersEventType.RENDERER_ADDDispatched when an item renderer is added to the list. When the layout is virtualized, item renderers may not exist for every item in the data provider. This event can be used to track which items currently have renderers.
TheFeathersEventType.RENDERER_ADD event type is used by
Feathers components with item renderers to indicate when a new
renderer has been added. This event type is meant to be used with
virtualized layouts where only a limited set of renderers will be
created for a data provider that may include a larger number of items.

starling.events.Eventfeathers.events.FeathersEventType.RENDERER_REMOVEDispatched when an item renderer is removed from the list. When the layout is virtualized, item renderers may not exist for every item in the data provider. This event can be used to track which items currently have renderers.
TheFeathersEventType.RENDERER_REMOVE event type is used
by Feathers controls with item renderers to indicate when a renderer
is removed. This event type is meant to be used with virtualized
layouts where only a limited set of renderers will be created for
