myGrid.groupBy is not a defined function

Hi, seems like there’s no way to make the “groupBy” feature to work.
I even try to copy the sample ( … group.html ) on a local page, but everything works except the grouping.
I found out the there’s no occurrence of “groupBy” function into standard version grid component (and not even in the suite), but at the same time i didn’t read that it is only for “pro” users.
What did i miss?

Unfortunately the groupBy method is available in PRO version of the dhtmlxgrid only.
Here you can find the comparison table of the dhtmlxGrid editions: … ions.shtml

Sorry u are right, i was confused cause i was referring to this page
Thank u!
