TreeList

Multiple Row Selection

Documentation

In this demo, the TreeList widget uses the multiple selection mode. To select a row, click the check box located in this row. Note that selection is non-recursive by default, that is, only the clicked row is selected, but not its nested rows. To make it recursive, click the «Recursive Selection» check box under the TreeList. You can also select all rows at once by clicking the check box in the column header.
