Having multiple sub menus with the same number of columns is leading to duplicate ids in the html.
Create a mega menu where multiple sub items have the same number of columns. In our project, we have several menus with 4 columns which was causing all of them to have the same id "tb-megamenu-column-5".
Sanitize the generated id with Html::getUniqueId, or use another criteria to generate the id of the columns, not the number of cols.
