[Mapserver-users] Q: Dynamic Legends

[Van Ulden, Joost]

The dynamic HTML legend will allow you to hide the classnames but still show
the layer title for inactive layers.  Not sure if this is exactly what you
need but it may be a start.  Here is a sample:

[leg_layer_html order_metadata=WMS_ORDER visibility_flag=15 opt_flag=15]
<TR> 
<TD>[if name=layer_status oper=neq value=2]<INPUT type=checkbox name="layer"
value="[leg_layer_name]"
onClick="mapForm.INPUT_COORD.value='';mapForm.zoomdir.value='0';mapForm.mode
.value='browse';mapForm.target='_self';mapForm.submit()" [if
name=layer_status oper=eq value=1]CHECKED[/if]>[/if][metadata
name=WMS_TITLE] 
</TD>
</TR>
[/leg_layer_html]
[leg_class_html visibility_flag=15]
[/leg_class_html]

Hope this helps!
