Can you freeze the first row (the header) of a DataTable group?

Suppose that a group in a DataTable has more than 100 items. Is it possible to freeze the top row (the row with the folder icon and the name of the group) while scrolling through the items in the group?

Unfortunately, the current implementation of “frozen rows” feature cannot support such scenario.

I see. Is there anyway I can submit this as a suggested feature?

A solution that we assume is quite complex, so we do not plan to implement it in the foreseeable future. If it’s critical, you can contact sales@webix.com to estimate/request the needed feature.
