How do I access the details from a nested json response using ng-repeat?

I have a nested json response and I am using a custom directive since my response changes dynamically. I am displaying the response in panels. But i don’t know how to access the contents presented in sub arrays i.e sub scenarios and sub list.

CUSTOM DIRECTIVE:

<div class="panel success panel-heading panel-height " ng-repeat="item in items">

        <h3 class="panel-title">
            <p class="font">
                <span class="pull-left"><i class="fa fa-check-circle"></i></span> 
                <span class="pull-right">ID: {{item.Id}}</span>
            </p>
        </h3>
        <hr COLOR="black" WIDTH="100%" >
        <br>
        <p class="font">DESCRIPTION: {{item.Scenario_desc}}</p>
        <br>
        <p class="font">STATUS: {{item.Status}}</p>
        <br>
        <ul>
          <li ng-repeat= "sub in item.sub_list"></li>
          <ul>
            <li ng-repeat= "subb in sub.Scenario_sub">
              {{subb. sub_msg}}
            </li>
          </ul>
        </ul>

     </div>

HTML FILE:

<div class="row" ng-if="showresult" >
    <br>
    <br>
     <!-- <div class="row"> 
             <div class="col-lg-3 col-md-6">  -->

                <div ng-repeat="list in itemsList">
                    <show-hide items="list"></show-hide>
                </div>

            </div>
        </div>

JS FILE:

$scope.itemsList = [[
            {
              Id: '2343',
              Desc: 'Not Found',
              Status:'Negative'

            },
            {
              Id: '124213',
              Desc: 'Found',
              Status:'Positive'

            },
            {
                  Id: '3',
                  Desc: 'Found',
                  Status:'Positive',
                  sub_list: [{
                    Scenario_sub: {
                      sub_id:'234235',
                      sub_msg: 'Not available currently',
                      sub_status: '20A',
                    },                        
                    Scenario_sub: {
                      sub_id:'12334',
                      sub_msg: 'available currently',
                      sub_status: '10A',
                    } 
                  }]
                }]]
