ComboBox is a very common component used in many projects, what if we can extend its features?
The following example creates a custom tooltip for each item in the DropDown List, data provider for these tips can be set in the ComboBox dataProvider as follows:

[Bindable] private var comboProvider:Array = [
		{label:"item 1", data:{tip:"bla bla bla .."}},
		{label:"item 2", data:{tip:"bla bla .."}},
		{label:"item 3", data:{tip:"bla bla bla bla .."}}
		];

source code available via flash context menu

Next step is to implement custom controls to make this ToolTip interactive by adding some like “rename” and “delete”
I’ll get back to you soon with another example
