%ZEN.Component.listBox

deprecated class %ZEN.Component.listBox extends %ZEN.Component.abstractListBox

This is a listBox control implemented using HTML primitives.
It offers some features not provided by the HTML select control.
The contents displayed by the combobox dropdown list are defined using a set of %ZEN.Auxiliary.option objects.
For example: 
<listBox>
<option value="1" text="Apple" />
<option value="2" text="Banana"/>
</listBox>
The listBox control will support both drag and drop. If dragEnabled is true, then the user can drag values from the list box and drop them on other drop-enabled components.
If dropEnabled is true, then values can be dropped onto the list. They will be appended to the end of the list. If both drag and drop are enabled, then it is also possible to move items within this listBox using the mouse.
