Problem in tab redirection in laravel using adminlte template

I am having same problem as mentioned here. I have form on my Add tab. and listing on my Manage tab. If I submit the form from Add tab the message should display on that tab only. It should not go to the Manage tab which is active by default.

I am trying to implement that the code of solution mentioned in the link above in my tab menus but its not working.

<ul class="nav nav-tabs mb-4" id="custom-content-below-tab" role="tablist">
                <li class="nav-item">
                    <a class="nav-link "  id="manage-tab" data-toggle="pill" href="#custom-content-below-manage" role="tab" aria-controls="custom-content-below-manage" aria-selected="true">Manage</a>
                  </li>
              <li class="nav-item">
                <a class="nav-link " id="create-tab" data-toggle="pill" href="#custom-content-below-add" role="tab" aria-controls="custom-content-below-add" aria-selected="false">Add</a>
              </li>
            </ul>
            <div class="tab-content" id="custom-content-below-tabContent">
              <div class="tab-pane fade " id="custom-content-below-add" role="tabpanel" aria-labelledby="create-tab">

                          //manage tab content 

              </div>
              <!-- /.create-tab -->
              <div class="tab-pane fade " id="custom-content-below-manage" role="tabpanel" aria-labelledby="manage-tab">

                 //add tab content

              </div>

            </div>

Actually i don't understand the code of solution from link given. what is $tabName taken for. Still I tried. But its not showing the contents and menus are not working properly.

Please guide. Thanks in advance.
