How to customize existing toolbar in DocumentEditorContainer

Document Editor Container allows you to customize(add, show, hide, enable, and disable) existing items in a toolbar.

• Add - New items can defined by CustomToolbarItemModel and with existing items in toolbarItems property. Newly added item click action can be defined in toolbarclick.

• Show, Hide - Existing items can be shown or hidden using the toolbarItems property. Pre-defined toolbar items are available with ToolbarItem.
• Enable, Disable - Toolbar items can be enabled or disable using enableItems
