React 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.
To give you the ability to edit code on the fly, the demo uses SystemJS. For this reason, launching the demo takes some time. We strongly recommend that you do not use this approach in real projects.
