I'm using TB Megamenu on a D8 site. With a bit of tweaking all working fine.. However, when I try to have a third level of links I can't get this to show expanded. In the menu itself the level 2 item and all level 3 items have 'show as expanded' ticked on, to no avail.
In the TB toolbox it shows correct, I can have the level2 item function as header (group set to 'yes') and have the feel 3 links in one or more columns under level 2. But on the site I get a toggle arrow, and no leave three links. And clicking level 2 does not show the level 3 items underneath (I think they're rendered on the right, outside my 100% width submenu).
level 1 link | level 1 link | etc
level 2 nolink (group yes) | normal level 2 items
level 3 items always expanded as group | level 3 items
(when looking at mobile the level 3 does appear under there level 2, but again not expanded, only unfolding when clicking the level 2 item..)
I have a suspicion I could change the one of the twigs (tb-megamenu-submenu.html.twig? tb-megamenu-subnav.html.twig?) but don't know how..
All help massively appreciated!
