Freeze header in BSP page which is using Grid Layout

Hi Experts,

I have been working on a requirement where i need to freeze the header of a content. That is the header part should not scroll when the user is scrolling down the page.

Here, the standard code is using Grid Layout to display header as well as body. I mean the header is also displayed like part of body.

Col1 Col2 Col3

AAA 1 B

BBB 2 C

CCC 3 D

Here code is like

Grid Layout

Loop to display headings

Loop to display content

End of grid layout

Please through some light on how to achieve this.

I have tried with document.body.ScrollTop .. but it is not working

Thanks in advance.
