How To Create Dropdown Inside Dropdown Using Bootstrap

I want to create a drop-down, But I am not sure it is a drop-down or something else coz I am new to HTML environment. What I want to create is When I clicked on the Indian Spices,

Solution 1:

I think this is what you were looking for. You can do the rest bit of the designing yourself. Check the snippet.

$(document).ready(function () {
  $('#head__top').on('click', function(){
    if($('#innerCollapse').is(':visible')) {
      $('#innerCollapse').hide();
    }
  });
  $('#head__sub').on('click', function() {
     $('#innerCollapse').fadeToggle(300);
  });
});

<div class="col-sm-12">
  <h4 id="head__top">
    <a class="font-weight-normal badge badge-light bg-white" data-toggle="collapse" href="#collapseExample" role="button" aria-expanded="false" aria-controls="collapseExample">Indian Spices</a>
    <span class="col-sm-3"></span>
    <span class="col-sm-3"></span>
    <i class="fa fa-angle-down text-fade" data-toggle="collapse" href="#collapseExample" role="button" aria-expanded="false" aria-controls="collapseExample" style="font-size:18px"></i>
  </h4>
  <div class="collapse" id="collapseExample">
    <h6 id="head__sub">
    <a class="dropdown-item" role="button" aria-expanded="false"
		 aria-controls="innerCollapse">Pepper
    <span class="col-sm-3"></span>
    <span class="col-sm-3"></span>

    <i class="fa fa-angle-down" aria-hidden="true" data-toggle="collapse" href="#innerCollapse" role="button" aria-expanded="false"
		 aria-controls="innerCollapse" style="font-size:18px"></i></a>
     </h6>

  </div>

  <div class="collapse col-sm-3" id="innerCollapse">
    <h6>
      <a class="dropdown-item">Black Pepper</a>
      <a class="dropdown-item">White Pepper</a>
    </h6>
