Tab Panel

Tab Drag & Drop

This demo illustrates how you can allow end-users to reorder, add, and remove tabs within the DevExtreme TabPanel component.

Reorder tabs

Wrap the TabPanel into the Sortable component and set the following properties as needed:

  • filter
    Specify a CSS selector to indicate draggable items. This demo sets filter to .dx-tab.

  • itemOrientation
    Set this property to "horizontal". When a user drags a tab, remaining items move left and right to designate the drop target.

  • onReorder
    Implement this handler to synchronize the dataSource with reordered tabs.

  • moveItemOnDrop Set this property to true to update markup after a tab is dropped.

Add or remove tabs

This demo adds and removes tabs in the following two functions:

  • addButtonHandler - a click handler for the "Add Tab" button.
  • closeButtonHandler - a click handler for a tab's Close icon. The demo uses the itemTitleTemplate property to display this icon.

Both handlers modify the TabPanel's dataSource.
