CMS Populated Mega Menu with Sub Levels

Hello,
I’m seeking a method to create a CMS-populated mega menu with sub levels.
The issue is not creating the actual menu with Collections nested inside Collections but instead not reaching the 20-collection list limit on an individual page.

I would appreciate any suggestions.

A few options, all of which involve custom code to overcome that limit.

OPTION 1 - BUILD LOCALLY
You use 1 or 2 collection lists max to get all of the data, and then script to assemble your hierarchy

OPTION 2 - BUILD SPECIALLY, AND FETCH IT
Have a special page that uses 20 collection lists to build the menu.
Your script then gets that HTML using fetch, and embed it in the current page.

OPTION 3 - REVERSE PROXY
Build it on a special page, but the reverse proxy will do the fetch and aggregation.
Advantage here is performance.

Thank you Michael, appreciate your input. Sorry to hear that this cant be solved natively in Webflow.
