How can I add a full width html block to my mega menu?

Hi all,

Relatively new here and struggling with something that’s probably quite straight forward…
I’m trying to add a full width html block to Warehouses Mega Menu

I’m trying to amend the existing block to include something new in its settings and so far I have :

  • amended the schema

  • added a reference to the ID in the related mega menu snippet

How do I actually get the content to render out? I see the text editor appear in the settings but obviously does nothing and the mega menu doesn’t have its own template?
Its a bit odd as the template doesnt seem to make any reference to the snippet at all but obviously works as its part of the theme
