React Gantt - Context Menu
Our feature-complete Gantt component allows you to create and customize its context menu as needed. Use the contextMenu property and contextMenuPreparing event to access and manage context menu items.
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.
