...if you want to add a Drupal block to your TB mega menu, you have to first add the block to the block ui before it will be available in the TB UI. We typically suggest that you create a hidden region in your theme. Meaning you add a region to your theme's info yaml but not add the region to any templates.

This from #3 💬 I cant see any mega menu block! Closed: works as designed worked great for me and was the solution I needed after quite a bit of frustration trying to get my views blocks to show up in the TB Megamenu UI. Thanks!
