Mega Menu

Hello,

Is there a recommended / working module for Backdrop CMS to implement a "Mega Menu"?

Specifically, I want a block to open when clicking or hovering over a menu item, where I can display multiple links, images, search forms, views content, etc.

For example, in Drupal I have often used:
https://www.drupal.org/project/tb_megamenu
https://www.drupal.org/project/om_maximenu

For Backdrop CMS, the only thing I've found in this direction is:
https://backdropcms.org/project/menu_attach_block
Unfortunately, I can't get it to work (no matter what I try, a block never appears in my menu...).
