I am using the MVC Menu component, and I am using is in a slide out div. So hit a menu button, a div slides out from the side of the screen, showing menu choices. However, the menu itself (with a Vertical Orientation) fills up the entire div, and submenu items are not showing up because I assume they're being cut off by the div. I have tried setting an HtmlAttriibutes on the main menu itself, with a style of z-index: 1000 to ensure it's the top most, but that doesn't work. I've also tried using PopupCollisions to false, but I guess that's for something else entirely.
So my question is, if a menu is part of a popup or slide out div, how to ensure sub menu items get displayed, and secondly, where do I put in the URLs for these menu items? All the demos only show the menus, but not what should happen when a menu is clicked?
