Drop down tab

JayKappy — Wed, 01 Dec 2010 13:25:07 GMT

I have a tab in my project that would to open via a click. I am now trying to get this to drop down (open) with a MouseEnter. I can get this to work, sort of.....
With the code below I can get the tab to open as normal but if I move the mouse off the original tab it closes. I want the user to be able to move the mouse off the tab and utilize the new size of the tab as it expands....I need this because I have specific buttons in the tab after it expands...
That make any sense?

I am looking for a way to open the tab (that is working) and have the user be able to move ANYWHERE in the newly opened tab to be abel to select things in the tab....
Then once they leave the newly defined tab it will close...

Right now it works like that BUT only for the original tab size...not the expanded tab

Thanks....any help would be appreciated.....
