Function: multi-level navigation. / Plugin for version 2!

[frontlineco]

As I said before, I am not very good at coding but I noticed something in my code that might be a problem, you would know best. I am using a drop-down menu script to create the menu via CSS and I have it coded as follows:

Code:

<td><ul id="nav-one" class="dropmenu">
<?php menu_master(); ?>
</ul>

But once the page is online and the plugin generates the code it adds its own class:

Code:

<td><ul id="nav-one" class="dropmenu">
<ul class="menu"><li><a href="http://www.redemptionoutreachcenter.com/gscms/">Home</a> etc........

Would the two conflicting classes cause nothing to be showing up? If so, is there a way to solve this problem? Thank you so much for helping out.
