that we can display a hierarchy of WMS layers. Not very difficult, I‘m
using a treeview component which allows me to specify the parent of each
node. One thing to keep in mind is that you must keep the layers indexed
properly, otherwise the GetMap request (when working with OpenLayer.WMS) orders
the layers wrong on the request and some layers are hidden undereath others. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>We have discussed sub-layers on the WMC/OWS-Context and Mapbuilder
lists.<br>
<br>
I think the current idea is to set up a "group" flag for a layer so
that <br>
multiple layers can be grouped in a legend in a hierarchical manner.<br>
<br>
Could you please expand on your idea of the "Customizable Layer".<br>
