You can nest other RadControls within RadMenuStrip. This feature gives you enormous flexibility in building functionality into applications and allows you to create complex custom user interfaces featuring text boxes, combo boxes, or other custom elements within the menu area.

This example demonstrates RadMenuStrip with a menu item which contains RadComboBox. The combobox is actually a RadComboBoxElement which enables it to inherit its properties from the parent menu item. RadMenuComboItem has a ComboBoxElement property which exposes the combobox instance. As the combobox element takes all available space its width could be changed by setting the ComboBoxElement.MinSize property.
