In static content, you can add ul li (in html structure to build content)

This is just an example:

" l class="dropdown-mega-menu">

<li>
<ul class="dropdown-submenu-ct">
<li class="level1"><a href="{{store url="../en_rtl/blog"}}">Blog Grid</a></li>
<li class="level1"><a href="{{store url="../fr_rtl/blog"}}">Blog List</a></li>
<li class="level1"><a href="{{store url="../fr_rtl/blog"}}beauty">Blog Categories</a></li>
<li class="level1"><a href="{{store url="../fr_rtl/blog"}}tag/News">Blog With Tag</a></li>
<li class="level1 dropdown-submenu"><a href="{{store url="../fr_rtl/blog"}}blog13">Blog Detail<span class="toggle-menu"><span class="icon-toggle"></span></span></a> <span class="toggle-menu"><span class="icon-toggle"></span></span>
<ul class="dropdown-menu-ct">
<li class="level2"><a href="{{store url="../fr_rtl/blog"}}gucci-garden-opens-in-florence">Blog Detail Video</a></li>
<li class="level2"><a href="{{store url="../fr_rtl/blog"}}the-best-street-style-from-berlin-fashion-week-fall-2018">Blog Detail Image</a></li>
