The Oracle Apex shuttle item is a neat way to select a number of values. It is however not so user friendly when the list of choices is very long. In this case it is useful to be able to limit the list of choices.
When you implement the limitation in the LOV-query of the item, the limitation will also be applied to the selected values. Usually this is not the desired behavior.
This behavior is avoided when the restricting of the left shuttle pane using JavaScript. I have created a Dynamic Action plug-in to do this. The choices in the left shuttle pane are evaluated case insensitive against the content of the search item. If the search item contains more than one string ( separated by spaces) all the strings should occur in the shuttle value. The search string ‘INVOICE 2013’ returns only values that contain ‘INVOICE’ (independent of case) and ‘2013’.

The plugin attributes are the shuttle item and the select item. The plugin needs to know the select item to disable submit when enter is pressed.

You can see the plug-in in action on:

As usually you can find the plugin on
