I'm new to Zimbra and working on a new custom skin. Things are going very well, but I know that in the near future I'll have to extend some of the current functionality within this suite. Just a small addition is to add hover state to menu items in the Tree. For instance...adding a background color upon hovering over Inbox, Sent, etc. by adding a classname like ZHover.
The other method might be to add some sort of listener to a core js file. I'm just not sure how involved this might be or even if I understand which js file would be the correct one to modify. It looks like there is a js\ajax\dwt\widgets\DwtTree.js file but not sure if that's the one I want to modify.
I apologize if this has been answered, but I couldn't find a response in my search. Any help on direction is greatly appreciated.
