What CSS command causes a menu to expand?

[Romuba]

I have followed the steps as closely as I can from the very good documentation provided but my menus don't open. In the udm-custom.js file I have set the orientation to "expand" but this gets changed when I use the Generator to create the CSS.

Am I missing something? What command in CSS causes the menu to flyout?

I believe you want to have the orientation set to "horizontal" or "vertical"

If you're using the CSS generator, and looking for the CSS that will open the menu, for Firefox and other compliant browsers, you'll be looking for the ":hover" pseudoclass
