I am using a front end framework that uses a flex layout. I started creating an admin page where I have sidebar, header, main sections. I want the sidebar and the header + main section to work independently. So if the sidebar has more data than the site of the browser window, it should use a scrollbar - but always try to fill up the whole space, so should have a height: 100%. The header + main sections should have a scrollbar, but the header should not be sticky - it should stay at the top even if the main section has lots of content.
I actually managed to accomplish this by adding overflow: initial to the main section - instead of overflow: auto. So the scrollbar is now appearing on the side of the whole container, not just on the side of the main section. However, by doing this, the sidebar doesn't get 100% height - if the main section has more content.
How can we fix this by not changing too much on the flex layout? I know for example, by making the sidebar fixed, it will kinda fix the problem, but isn't there a better, more elegant way of doing it?
