To view all items in the recycle bin, click View recycle bin at the bottom left of the table.
This shows you all deleted items of the selected category. The cells in the table are disabled, as deleted items cannot be edited.
To restore one item, click Restore at the right of the row. To restore multiple items, select them with the checkboxes and click Restore in the toolbar. They are moved back to the 'normal' data overview.
