The Gantt control allows you to perform quick actions by using context menu. When right-clicking the context menu, the context menu options are shown. To enable this feature, set the enableContextMenu to true. The default context menu options are enabled using the editSettings property. The context menu options can be customized using the contextMenuItems property.

To use the context menu, inject the ContextMenu module into the Gantt control.

The default items are listed in the following table.

Custom context menu items

The custom context menu items can be added by defining the contextMenuItems as a collection of contextMenuItemModel. Actions for the customized items can be defined in the contextMenuClick event and the visibility of customized items can be defined in the contextMenuOpen event.

To create custom context menu items for header area, define the target property as .e-gridheader.

The following sample shows context menu item for parent rows to expand or collapse child rows in the content area and a context menu item to hide columns in the header area.

You can show an specific item in context menu for header/content area in the Gantt control by defining the target property.

Touch interaction

To perform long press action on a row, context menu is opened, and then tap a menu item to trigger its action.
