[OpenLayers-Users] Layerswitcher with radio-buttons (Group all layers of type x)

[Michael Prieß]

Hi,

i have one base map and a few overlays of type X. Now i like to choose
between all typ X layers with the layerswitcher and only one overlay
of typ X should
be visible equalent like the baselayer. Is there maybe a fork of the
layerswitcher with this logic inside?

The code in HTML should look like the following:

    <select name="top5" size="3">
      <option>Layer1</option>
      <option>Layer2</option>
      <option>Layer3</option>
      <option>Layer4</option>
      <option>Layer5</option>
    </select>

Regards,

Michael
