I have build a custom Bootstrap 4 theme for my site. The site has a taxonomy base menu from all Drupal Commerce product categories (with parents, childs, parents (level 2 and 3) and it's childs (level 2 and 3).
So the parents are the Main buttons/links. If you hover those, you will see the Mega menu divided into columns (parents level 2 with childs level 2). And parents level 3 with childs level 3 in the same column as there parent level 2 like this example:

Can I use this module to build this multi column mega menu?

volegerThere are no custom content needs to be displayed. Looks like https://www.drupal.org/project/taxonomy_menu suits better for this case. The module provides MenuItemInterface derivatives based on the taxonomy term entities.
