                        <ul class="sub-menu children dropdown-menu">
                            <li><i class="menu-icon fa fa-sign-in"></i><a href="page-login.html">Login</a></li>

                            <li><i class="menu-icon fa fa-paper-plane"></i><a href="pages-forget.html">Forget Pass</a></li>
                        </ul>
                    </li>
                </ul>

It is pretty standard. Now I want to add second level of dropdown i.e below Buttons I want to have it's items as Button 1, Button 2, Button 3

so I try to put this HTML there:

<li class="menu-item-has-children dropdown">
            <a href="#" class="active" class="dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
              <i class="fa fa-puzzle-piece fa-2x"></i> Buttons</a>
            <ul class="sub-menu children dropdown-menu">
              <li>
                <a>Button 1</a>
              </li>
<li>
                <a>Button 2</a>
              </li>
<li>
                <a>Button 3</a>
              </li>
            </ul>
          </li>

Button when I click on Buttons to open up it's dropdown it instead closes the parent. What am I doing wrong?

Any help is appreciated.

The only way to solve this issue is to add javascript.

Add this to your js file:

$('.menu-item-has-children .menu-item-has-children a').on("click", function(e){
    $(this).next('ul').toggle();
    e.stopPropagation();
    e.preventDefault();
});

As you have not update any fiddle yet. Watching to your code what I have found wrong is with the class attribute which you have mentioned multiple times

<a href="#" class="active" class="dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
          <i class="fa fa-puzzle-piece fa-2x"></i> Buttons</a>

on above code you are using two classes remove class="active" and then try Hope it will help
