Trying to get a side nav sticky beneath top sticky menu plus full height

Hey everyone, happy Monday!

I’ve been trying to get a sticky sidebar as we explore rebuilding our main app in Wappler - it’s naturally easy to assign this to a header or navbar element, when I assign sticky to the header nav bar, and then the left side nav - there is no clear way to have an offset, or set this not to stick to the very top of the page (and then creates an overlay on top of the top nav menu).

I’e tried custom css with no luck. Has anyone achieved this and can point me in the right direction?
