R: Re: [OpenLayers-Users] Hide Overlay Laben in OpenLayers.Control.LayerSwitcher

Yes, you are right... 
This is the procedure that i used:

1- I modified the file ../lib/OpenLayers/Control/LayerSwitcher.js in this way:

       - I comment all the line  that contain dataLbl :

                            /** 
                             * Property: dataLbl
                             * {DOMElement} 
                             */
                             //dataLbl: null,
                              ........

                             //this.dataLbl.style.display = (containsOverlays) 
? "" : "none";    
                             ......

                             //this.dataLbl = document.createElement("div");
                             //this.dataLbl.innerHTML = OpenLayers.i18n
("Layers");
                             //OpenLayers.Element.addClass(this.dataLbl, 
"dataLbl");

                             .....

                             if (this.ascending) {
                                                            this.layersDiv.
appendChild(this.baseLbl);
                                                            this.layersDiv.
appendChild(this.baseLayersDiv);
                                                           //this.layersDiv.
appendChild(this.dataLbl);
                                                           this.layersDiv.
appendChild(this.dataLayersDiv);
                               } else {
                                                           //this.layersDiv.
appendChild(this.dataLbl);
                                                          this.layersDiv.
appendChild(this.dataLayersDiv);
                                                          this.layersDiv.
appendChild(this.baseLbl);
                                                          this.layersDiv.
appendChild(this.baseLayersDiv);
                              }

    after all i recompiled OpenLayers.js file  in this way :

 ../OpenLayers-2.11/build# ./build.py full.cfg OpenLayers.js

That's all ... There is anoter way to do that directly into the html file 
after:

 map.addControl( new OpenLayers.Control.LayerSwitcher({ ....

just add this line:

document.getElementsByClassName("dataLbl")[0].innerHTML =""

That's all.
