Live Preview
Allows you to see how the selected item will appear in your browser.
The Live Preview is updated at the same time you make changes to your items. That way, you always know how your menus will appear without having to go through the process of compiling your project or even previewing.
When a group is selected, the Live Preview shows how the background of the menu will appear. If the
toolbar option is selected, the preview will show how the actual toolbar hotspot will appear.
When a command is selected, the Live Preview shows how the selected command will appear against its parent group.
The Scope Selector
This advanced control will let you select which item or items
should receive the styles on the dialog.
By default, only the selected item will receive the style
changes, however you can choose from a variety of options to apply
the same style changes to a set of menu items all at once.
