Toolbar and Context Menu
The File Manager widget provides the following UI customization options:
- The toolbar option specifies the toolbar's visibility and available commands.
- The contextMenu option specifies the context menu's availability and its commands.
The toolbar and context menu support context-invariant and context-sensitive items that can be visible or hidden depending on user action.
Feel free to share demo-related thoughts here.
