Mobile menu nog showing

[CommanderK84]

I use Navwalker on several themes, all works fine.
But in a new template the mobile (dropdown) menu is not showing. It works on desktop when making the browser smaller, but not on mobile.

Demo site: bidoncolle.cc

Are you actually using the walker on this site? I can't see any Bootstrap markup being added or any bootstrap styles/scripts being loaded. The latter aren't loaded by the walker, you have to load them yourself.

If it's just disabled. What version of Bootstrap? What mobile? Can you please share the navbar markup? It's hard to tell what the problem might be without seeing the code. Have you also checked on another phone if it's a browser support issue?
