I am trying to make my own theme for drupal 8. but I am struggling with the menu. my menu looks something like this
- child 1.1
- child 1.2
- child 2.1
- child 2.2
but only the parents are visible.
I used the menu.html.twig file from the classy theme.
edit: I tried my theme on other site and there the children are displayed. so guess the problems was not because of theme. so i activated the stark theme, but also there I can't see my full menu tree. and the checkboxes show as expanded are checked
