I've been experimenting with block-based mega menus powered by a single custom block and the Interactivity API. Still a bit rough under the hood, but a successful proof-of-concept.

I am in the middle of writing a detailed tutorial for the WordPress Developer Blog, but wanted to share a quick overview here:

The link is in the article, but the code for this block is available here:

You beat me to it Nick! I was just going to get started on an interactivity api driven mega menu block next week.

Please do, would love to compare and contrast approaches!

Super cool, Nick! I’ve played with a few POCs for this but have also been waiting for some changes in 6.5. It would be cool if you could launch that contextual pattern modal so users can visually choose which mega menu to apply (though I do t think it’s extensible like that).

Yeah, there is definitely some UX/UI work to do on the block in the Editor, especially if you were to make this functionality available to users who are not that familiar with the Site Editor.

Nick this is great! We keep coming up with use cases for megamenus but have been unable to build with FSE yet. Really looking forward to seeing the detailed write-up! cc @michaelbragg

This is absolutely fascinating! I attempted to replicate this functionality before, but encountered challenges. It seems like it's time to delve back into it once more.

This stuff gets me fired up! Great work as always Nick!

There are a lot of new toys coming in 6.5 💪
