Scroll, then fixed position headers

I was wondering if there is any way someone has found to fix the headers of the chart so that once it reaches the top of the screen, the headers stay in view. Similar to this example

Ideally both the headers for the gird data, and the dates for the task view would remain as the user vertically scrolls. Any thoughts on how to do this effectively (without hacking together some custom js)?

the gantt headers are already fixed against inner scrolls of a chart.
E.g. when you scroll it down - header remains on a place … weaks.html

Did you mean something else?

Ah that makes sense. We display the whole chart, so it doesn’t have a vertical scroll. So we just needed to modify some of our code to get it to work. Thanks for the quick reply!
