I'd like to have a drop down box instead of a radio button for the
"search mode" choices.
Is it possible to change the html code in order to have this
functionnality ?!
Or maybe change "www.ageofconan-fr.com" by "Age of Conan" in the radio
text ?!
My understanding is that Google doesn't want people editing any bit of
the AdSense for Search code. So you are stuck with what they offer in
terms of formatting. See the "Code Modification" section on Google's
Program Policies https://www.google.com/adsense/policies
