Pivot Frozen Rows

Hi,
I’m working with the webix pivot product and i would like to know how can i frozen the first row of the pivot table.
I know I can do it with datatable, but looking for that pivot functionality on internet I didn’t find anything.

Thank you.
Claudio.

Edit:
Sorry, I have to change my request.
I need to freeze a specific row with a specific Id as i can do with datatable with the freezeRow function.

Thank You.
Claudio

Hello,

Unfortunately, Pivot and treetable (its inner grid) have no such feature, as they work with hierarchical data structures.
The topSplit and freezeRow features are supported only in the ui.datatable (data widget with a plain one-level data structure).
