This page has been loaded into the "body" frame. The submenus still work because the base Milonic .js files (milonic_src.js and mmenudom.js/mmenuns4.js) have been loaded into the page, along with menu_data_body.js, which contains the javascript code for the submenus. The code used to load the .js files into this pages is as follows:
<script type="text/javascript" src="milonic_src.js"></script>
<script type="text/javascript">
if(ns4)_d.write("<scr"+"ipt type=text/javascript src=mmenuns4.js><\/scr"+"ipt>");
else _d.write("<scr"+"ipt type=text/javascript src=mmenudom.js><\/scr"+"ipt>");
</script>
<script type="text/javascript" src="menu_data_body.js"></script>
Directory Paths. When loading the .js file, your would of course adjust the paths shown in the <script> tags above, to relect your own site's directory structure.
