Search filters

Hi, have a couple of issues would be great if you can suggest:

I have inserted an ‘open’ search filter into this CPT page:
https://yopune.com/compt_coaching/

This looks pretty ugly, so need any suggestions on that?
1. Is htere a way to open the fields ie categories, search by distance, business listings, Locality- but not open the options, those are opened only when user clicks on those?

2. In locality field, I am using this for multiple cities (currently two only- Pune & Bengaluru, with only very few options there for testing – it will become a long list once i put all areas…is there a way to show only the areas/localities in the selected location (city) ie have conditional options listed – i am not using neighbourhoods as that had its own issues.

3. In ‘search by distance’ i have selected only the ‘nearest’ option in the CPT setting, so this selection dropdown itself is not required, how can i remove that?

5. Can the “search” button be made smaller instead of stretching across the page?

Thanks very much!
