Add active class Laravel with JS .

Matching URL Segment :

<li class="{{ (request()->segment(2) == 'cities') ? 'active' : '' }}">  

So, this one will match any URL like /admin/cities, /user/cities/edit etc.

Starting with the URL

<li class="{{ (request()->is('admin/cities*')) ? 'active' : '' }}">  

/admin/cities/create or /admin/cities/1/edit.

Exact URL

<li class="{{ (request()->is('admin/cities')) ? 'active' : '' }}">  

Probably, the most simple one – you just check the exact URL and see if it matches:
