Menu items not showing up properly as a mega menu

Question

I need to make a mega menu similar to one as show in image below

So far i have been able to make it work to some extent example on jsFiddle HERE.

So far i have some design issue and one functionality issue.

When i try to hide the default text for each dropdown menu //$(this).find(".nav-info").hide(); then Menu 4 & 5 doesnt show up on right side.

I am actually trying to create a menu similar to one as on this website. One this website they also show a default text for parent menu which i dont need actually.

I modified script to show the first li of submenu it works find for Parent menu ONE, TWO but creates alighnment problem for MENU FOUR and FIVE.

I would appreciate if some can help me fix this issue...

Answer 1

Add the following in the head of the document,

    <!--[if lt IE 9]>
        <script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/html5shiv/3.6.2/html5shiv.js"></script>
        <script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/selectivizr/1.0.2/selectivizr-min.js"></script>       
    <![endif]-->

And use the method suggested by Rachel Reveley.

li:hover ul {display: block;}

The code adds support for HTML 5 and CSS3 on older browsers. And it seems to be working perfect for me.

Answer 2

Unless you are supporting IE6 then you don't need JavaScript to make a drop down menu work.

If you change your structure to something more like this

<ul>
    <li><a href="">Click me</a>
        <ul>
            <li>This is showed when Click Me! is clicked.</li>
        </ul>
    </li>
</ul>

you can simply do this with your CSS

li:hover ul {display: block;}
