How to create a 2 Tier Vbmenu on Navbar?

[joyceleong]

I have tried, putting a nested popup within the popup, but it doesn't seems to work well.

I did some changes on the style positioning:

<div id="mymenu_menu" class="vbmenu_popup" style="position: absolute; z-index: 250; clip: rect(auto, auto, auto, auto); left: 122px; top: 202px;">

Image as per attached.
sc_ff (1st image) - outcome under firefox (after I click on Communities both popup shows at the same time)
sc_ie (2nd image)- outcome from IE and safari (the popup wasn't able to display the whole div table, as you can see that it got trimmed off).

Has anyone tried it? Or able to just provide a little example?

Thanks.
