How to correctly specify where() when outputting in foreach?

Question

Laravel

Such situation. I display categories of clients. Accordingly, in the categories themselves, you need to display the clients corresponding to them.
From the controller I transfer these same clients, but how to display under each category of clients related to it?
Tried like this. Categories displays, but there are no customers.

@foreach($categories as $category)
          <div class="slider-title clients-row">{{ $category['title'] }} <span class="plus">+</span></div>
          <div class="slider-content">
            <ul>
              @foreach($clients->where('category', $category['id']) as $client)
              <li><span>{{ $client['title'] }}</span></li>
              @endforeach
            </ul>
          </div>
          @endforeach

Answer 1

Make the Category model link to the Client model with the hasMany() method

@foreach($categories as $category)
          <div class="slider-title clients-row">{{ $category['title'] }} <span class="plus">+</span></div>
          <div class="slider-content">
            <ul>
              @foreach($category->clients as $client)
              <li><span>{{ $client['title'] }}</span></li>
              @endforeach
            </ul>
          </div>
          @endforeach
