Another solution for this situation is to use the "tree" twig tag: https://github.com/jordanlev/twig-tree-tag -- it's less hacky, works in Twig 1 and 2, and IMO keeps the markup more straightforward (less ceremony around the mechanics of the loop and/or the macro). Only potential problem is that it requires PHP 5.4 or higher (but if you're using Twig v2 then that's no problem because you're already on PHP 5.5 or higher for that).
@ureimers your example gives exception:
Impossible to invoke a method ("recursiveCategory") on a string variable ("...html.twig").
Hi!
How to be with categories duplicates.
I mean if category has been rendered as a child, but it also will be rendered as a root category? So on page will be the two same categories rendered as a child category and as a root category.
Kind regards
thanks!
