Vue File Manager - Toolbar and Context Menu

The FileManager component provides the following UI customization properties:

  • The toolbar property specifies the toolbar's visibility and available commands.
  • The contextMenu property 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.
