<h2>How to use Mega menu component multiple times</h2>

<div class='multi-mega-menu mb-4'></div>
<p>
Mega Menu can be positioned in multiple places while initiating the library. Also, multiple Menus
can have different configurations as well. Below two ways, Menu can be called several times.
</p>
<ul>
<li>
<strong>Using multiple ID.</strong>
<p class="mt-3">
Call wrapper class multiple times for each distinctive ID.
</p>
<pre>
<code>
var megaMenuOption1 = {...},
megaMenuOption2 = {...};
window.addEventListener('load', function () {
window.A11yWrapper('#mega_menu_container1').megamenu(megaMenuOption1);
window.A11yWrapper('#mega_menu_container2').megamenu(megaMenuOption2);
});
</code>
</pre>
</li>
<li>
<strong>Using same class for multiple elements.</strong>
<p class="mt-3">
In below example, configuration object will be assigned sequentially. First object
will be assigned to the first Mega Menu and second object will be assigned to the second
Mega Menu.
If only one configuration object is passed then both Mega Menus will be built upon that
single configuration object.
</p>
<pre>
<code>
var megaMenuOption1 = {...},
megaMenuOption2 = {...};
window.addEventListener('load', function () {
window.A11yWrapper('.mega-menu-container').megamenu(megaMenuOption1, megaMenuOption2);
