Some months ago I published an Oracle Apex plugin to restrict the left side shuttle choices. You can read the original post here.
On the demo page the On Change event was used to refresh the left side list. My friend Alex Nuijten made the remark this was not very intuitive. The user needs to navigate out of the selection item to see the change.
So I changed the demo page to provide instant feedback. The selection is now refreshed after each keystroke. As this process is completely executed on the client the response is very fast. Only for very long list the user might notice a slight delay.
No changes to the plugin were needed. It can still be downloaded at apex.world

Here is how is was done:

Selection item
Name : P400_SELECTION
Type: Text Field

Dynamic Action
Name: Select on keystroke
Event: Key Release
Selection Type : Item
Item(s): P400_SELECTION

True Action
Name: Perform Selection
Action: Restrict Shuttle Values [plug-in]
Search Item: P400_SELECTION
Selection Type: Item(s)
Item(s): P400_SHUTTLE
Fire on initialization: No

Happy Apexing
