did you try using a stylemap in your code?
Something like this:
var styleMap_Gebiet = new OpenLayers.StyleMap({
'default':{
label : "${text}",
...
´
},
'select':{
label : "${text}",
}
});
Look at my code here:
http://www.dankoweit.de/Wetterdienste/hp_wetterdienste_auswahlkarte.html
This is a map which uses polygons to draw the selectable areas. Look at
lines 968ff in the source code http://www.dankoweit.de/Skripte/metarkarte.js
This File generates the following map for a special region:

I have done this. It is not very difficult but tricky :)
Here too look at the code between line 426 and 668.
