All the menu structure editing takes place on the Structure tab in the DHTML Menu Add-in editor. This tab is divided into two main areas:

Menu Editor
Here you can see the working model of your menu structure. You can expand the pop-ups by clicking respective items. New items can be created by typing their captions in the empty placeholders. At the top of the menu editor there is a toolbar containing essential commands for manipulating the menu structure.

Item Properties

Here you can set the basic properties of every item - these regarding navigation, like caption, destination URL as well as those responsible for visual aspects such as caption font, color and item icons.
