Adapting a HTML/CSS dropdown menu to multi-level
- by Adam Nygate
Ive been trying to make the original dropdown into multi level for a site im working on. All of my attempts have failed (. For some reason i can only do "margin-right" to align the elements, and this causes some problems. I think it has something to do with the position attribute.
Here is my HTML:
<ol id="nav">
<li><a href="index.php">Home</a></li>
<li class="dropdown_alignedLeft">
<a href="">Products</a>
<ul><li class="dropdown_alignedRight">
<a href="">iPoP</a>
<ul style="margin-right:-400px; top:0px;-webkit-border-top-right-radius: 5px;border-top-right-radius: 5px;-moz-border-radius-topright: 5px;"><li><a href="customers.php?category=ipop">iPoP - Network Solutions for Vessels</a></li></ul><li class="dropdown_alignedRight">
<a href="">Cameras</a>
<ul style="margin-right:-400px; top:0px;-webkit-border-top-right-radius: 5px;border-top-right-radius: 5px;-moz-border-radius-topright: 5px;"><li><a href="customers.php?category=icam">iCam 501 Ultra - Intrinsically Safe Digital Camera with Flash</a></li></ul><li class="dropdown_alignedRight">
<a href="">BNWAS</a>
<ul style="margin-right:-400px; top:0px;-webkit-border-top-right-radius: 5px;border-top-right-radius: 5px;-moz-border-radius-topright: 5px;"><li><a href="customers.php?category=bnwas">BNWAS - Bridge Navigation Watch Alarm System</a></li></ul><li class="dropdown_alignedRight">
<a href="">Lighting</a>
<ul style="margin-right:-400px; top:0px;-webkit-border-top-right-radius: 5px;border-top-right-radius: 5px;-moz-border-radius-topright: 5px;"><li><a href="customers.php?category=peli">Peli 2690 - Intrinsically Safe LED Head Lamp</a></li></ul><li class="dropdown_alignedRight">
<a href="">Communication</a>
<ul style="margin-right:-400px; top:0px;-webkit-border-top-right-radius: 5px;border-top-right-radius: 5px;-moz-border-radius-topright: 5px;"><li><a href="customers.php?category=handy">Ex-Handy 06 - Intrinsically Safe Cell Phone</a></li></ul>
</ul>
<li class="dropdown_alignedLeft">
<a href="">Customers</a>
<ul>
<li><a href="customers.php?category=maritime">Maritime</a></li>
<li><a href="customers.php?category=non">Non-Maritime</a></li>
<li class="dropdown_lastItem"><a href="customers.php?category=organizations">Regulatory Organizations</a></li>
</ul>
<li><a href="order.php">Product Enquiry</a></li>
<li><a href="contact.php">Contact Us</a></li>
<li class="dropdown_alignedLeft">
<a href="">Company</a>
<ul>
<!-- <li><a href="">About Us</a></li> -->
<li><a href="newsandpr.php?category=News">News</a></li>
<li class="dropdown_lastItem"><a href="newsandpr.php?category=Press Release">Press Releases</a></li>
</ul>
</ol>
