multiple select in Tree without shift or ctrl key

[jzssga]

Hi,


I am trying to allow multiple selection in a Tree without the use of shift or
ctrl key. So basically, when the user clicks a new item, it will retain the
previous selections. I tried to set tree.selectIndices manually, but it always
clears the selections first and then redraw the new selections. Is there
another way to do it so that the current selections are not cleared?

thanks

Jay
