How can I increase the font size of a RadMenuItem when it's displayed as a child item (in a popup)? Simply setting the FontSize property doesn't seem to do it.
As you can see, the RadMenuItem "Item 2.1" has a different FontSize and all its children are inheriting the same value. If you have something else in mind please send us more information (perhaps if you are using a different theme?) and if possible a sample project.
