My problem is that writing a whole custom component is too involved for the
few time I have and your method seems to work quite well.
The only trouble I have (as described in my previous reply) is that the
ComboBox should fire a change event everytime an item is selected while it
stays opened. By default the ComboBox is only firing this event after it
closes.
However listening to the dropdown (the List component in the ComboBox)
property's ListEvent.CHANGE seems not to cut it. It would be great if you
would have a workaorund for this!
Best,

I'm by no means on Alex's level of Flex knowledge, but a Button combined
with a Menu component would work too. You wouldn't get into resizing issues
and you'd still be able to do styling without resorting to UIComponent first
principles. :)

I've made a short test and that seems to work so far. Thanks for the hint
Ben!
I almost started to try writing a custom component from a Button and a
List
wrapped into a UIComponent as Alex Harui suggested in a message I've found
but seems that that's not necessary.

Something like:
package
{
import flash.events.Event;
import mx.controls.ComboBox;
public class ComboBoxNoClose extends ComboBox
{
public function ComboBoxNoClose()
{
super();
}
public override function close(trigger:Event = null):void
{
if (trigger != null)
super.close();
}
}
}

Does anyone know how to modify the ComboBox so that it stays open after
selecting an item?
I need such a ComboBox for a client that opens/closes only if the user
clicks on the 'header area' of the ComboBox or that closes only if
clicked
outside the ComboBox.
The use case for this is that the ComboBox will have custom item
renderers
that contain (for example) a CheckBox and a Label and the user should be
able to make several selections without the ComboBox closing inbetween.
I've made this before by wrapping all the stuff into a Panel and
changing
the Panels height on close so that only the header is visible but that
method is rather suboptimal, especially for skinning.
Would be great if somebody has a workaround for this!
Thanks in advance!
Sascha
