The Bootstrap Toolbar control provides visual interface for creating simple hierarchical toolbars on pages of your web applications. The toolbar control displays a set of buttons arranged in groups.
All root-level toolbar items are instances of the BootstrapToolbarItem class. A collection of these items is accessible through the BootstrapToolbar.Items property. The MenuItem.BeginGroup property specifies whether a menu item starts a new menu group.
Each toolbar item can have multiple child items, which are specified as elements of the parent item’s Items collection. Note that all root-level toolbar items are BootstrapToolbarItem objects, while items of subsequent hierarchy levels are BootstrapToolbarMenuItem objects.
A root-level menu item that has child items is rendered as a drop-down button displaying a hierarchical popup menu when clicked.
