Laravel-为什么我的代码没有显示所有折叠？

Question

此代码需要显示每个“子类别”的所有“子类别” 但是查看结果仅是第一个子类别。 我想念哪里？

查看1：

@foreach($treeView as $category)
 <div  class="collapse multi-collapse collapse in " id="8"  >         
   <div class="col-md-2"> {{ $category->account_name}}</div>
      <div class=" float-right"><button class="btn btn-success" data-toggle="collapse" data-target="#{{ $category->id}}8" aria-expanded="false" aria-controls="{{ $category->id}}8" @click="getSubaccount(); getNumberrawaccount();">
           <span class="glyphicon glyphicon-eye-open"></span></button></div>

  <br>                     
<div class="list-group">
@if(count($category->subcategories))
@include('tree2',['subcategories'=>$category->subcategories])
@endif
   </div>
@endforeach

查看2：tree2

<div class='list-group'>
     <br>
      @foreach($subcategories as $subcategory)
    <div class="list-group col-md-12">
     <div  class="collapse multi-collapse" id="{{ $category->id}}8" >
             <div class="col-md-4"> {{ $subcategory->subaccount_name }}</div>
             <div class=" float-right"><button class="btn btn-success" data-toggle="collapse" data-target="#{{ $subcategory->id}}" aria-expanded="false" aria-controls="collapseExample2">
              <span class="glyphicon glyphicon-eye-open"></span></button></div>
    </div>
        </div>
  @endforeach
  </div>

谢谢
