Chris Ligon commented on RF-7921:
---------------------------------

I had a drop down menu in a rich:dataTable and it worked fine (no offset).  
But, when I put the rich:dataTable inside of a rich:tab this offset issue 
presented itself. 

Mano, could you explain a little bit about what this piece of code is doing?  
Why are you doing the layer.replace part?  It seems that maybe you are escaping 
the :, but why is that?

This workaround works to some extent.  The problem is that for another dropdown 
menu (with sub-menus) outside of the rich:dataTable this script causes errors.  
Basically, the menu does not drop down, it's not visible at all.  And, after 
removing the mouse from over the menu item, I see just below the menu item, 
"/:/g/:/g".

Is there a way to limit the scope of this script so that it just works on the 
dropdown menus that need it?

> The popup list of the drop down menu is wrongly positioned when one scrolls 
> the page. It is shown too far below it's anchor point (i.e. it is not 
> directly connected to it's anchor point) - the offset changes on scrolling 
> (i.e. the more one scrools down, the farer below it is shown)
