I need freeze header of treetable
not clear what you mean. header is always frozen.
if you need to freeze top row, then your snippet is almost right.

By frozen I mean always stay on top, not hiding when scrolling down

  1. set autoheight = false
  2. set scroll = “y”

I know about it, but I mean something else. In primeface datatable has the “stickyheader” attribute, and I need something like it in webix treetable
