Dedecms Dream navigation Bar Two-level menu implementation method

Dede navigation drop-down menu, one-level column add level Two drop-down menu

Using dedecms5.6--5.7

Paste this code into the templets\default\head.htm file.
<!--//Level two sub-category drop-down menu, consider SEO reasons placed at the bottom--
<script type= ' text/javascript ' src= ' {dede:global.cfg_cmsurl/}/images/js/dropdown.js ' ></script>
{dede:channelartlist typeid= ' top ' cacheid= ' channelsonlist '}<ul id= ' Dropmenu{dede:field.typeid/} ' class= ' Dropmenu ">
{dede:channel type= ' son ' noself= ' yes '} <li><a href= "[field:typelink/]" >[field:typename/]</a>< /li>
{/dede:channel}
</ul>
{/dede:channelartlist}
<script type= "Text/javascript" >cssdropdown.startchrome ("Navmenu") </script>

After re-generation and look at the effect, you will find that the navigation bar has appeared in the drop-down menu, but the background is transparent, because there is no background image.
You need to put the DedeCMS5.5 program folder \dede\img in the mmenubg.gif (green background image for the green theme template) or DedeCMS5.5 program folder \templets\images mmenubg.gif ( Blue background picture, for blue theme template) copy to DedeCMS5.6.7 program folder/templets/default/images below, now you look at the effect, hehe, the navigation bar is not already appear familiar drop-down menu.

Here's the whole code:

<!--//bottom template-->
<div class= "Footer w960 Center mt1 Clear"
