With Easy Menu you can have as many submenus as you want.
Let's take a simple Easy Menu example:
<div id="div1"></div><oem:EasyMenu id="EasyMenu1" runat="server" AttachTo="div1"> <Components> <oem:MenuItem InnerHtml="Red colors" ID="menuItem1"></oem:MenuItem> <oem:MenuItem InnerHtml="Green colors" ID="menuItem2"></oem:MenuItem> ...
</Components></oem:EasyMenu>
Let's say on each item of the menu, we want to add subitems. Let's say for "Red colors"
we want to have the items Red, Purple and Maroon. All we need to do is add a new
Easy Menu and attach it to the "Red colors" item. Here's how:
<oem:EasyMenu id="EasyMenu21" runat="server" AttachTo="menuItem1"> <Components> <oem:MenuItem InnerHtml="Change to Red" ID="menuItem211"></oem:MenuItem> <oem:MenuItem InnerHtml="Change to Purple" ID="menuItem212"></oem:MenuItem>...
and so on for every Easy Menu.
