A question about row selection

Suite and Optimus Suite 5
#1

If the multi-select is enabled,

myGrid.enableMultiselect(true);

could I reserve the rows of previously selected when I click a row by left mouse button?
That means, could I select multi-rows without press the ctrl key in the keyboard.

It is better to change another admin in the product discussions of dhtmlxGrid/TreeGrid, I think.
Who agrees with me?

#3

Unfortunately such feature is not supported.
