Component Question - listBox

[vosgien]

Hi,
I've looked at the new components section and the tutes concerning customizing components, but I cannot fathom what I want to achieve, so I'll explain in the hope that some kindly soul can help me.

I am using a list box to load in a list of vars from a text file for a multiple choice quiz.
When an item is clicked on it is highlighted - so far so good. When a second or subsequent item is clicked it is hiighlighted, and the previous highlight disappears.That is the default action.

How can I adjust the component (or what code can I use)so that each item clicked stays highlighted ?

Cheers

hey, sorry guys I have just realised that this should be posted in the Components forum, I will not repeat(never had a cross post yet) it but hope that a moderator will move it. OK
