Hi!
1. See 4.
2. Well, I don’t have a snippet, because it highly depends on your website structure and the actual code. I’ve crated a quick snippet that might help you: https://jsfiddle.net/0zoqgovc/
3. If you want each group next to each other like this it’s possible with some custom css:
[html]div.ajaxsearchpro[id*=’ajaxsearchprosettings’].searchsettings {
width: auto !important;
}[/html]
You can add this css on the plugin options Theme Options -> Custom CSS panel: http://i.imgur.com/xGGX9Ia.png
4. Will see what I can do, but I cannot promise this – it’s much more complicated than it seems unfortunately.
5. The code is still there, I can see it in the theme code viewer, proof: http://i.imgur.com/Yf4yDaX.png
Once you remove it correctly, it will start working again.
