Editing/Customizing few things in working Wordpress site

Hi, I have a web site up and working ([login to view URL]) but have to customize it a bit. The original developers don't have time right now but I'd like to finish the web page. There are 2 things to fix and I think it shouldn't be complicated for someone skilled: 1) On my page there are 2 search engines: The one on the "main page" and the other one on "Advanced search" page.(both have Goolge geolocation as search engine) Under "advanced search", when I enter (for example) the city of "Barban, Croatia" it looks whether there is a property (house for rent) in that city, and if not found it gives a predefined radius and shows all the other listed houses for rent within that radius (circle). (see picture: [login to view URL] ) . And that's fine. The radius is set in Admin options of Wordpress. But on the MAIN PAGE's Search, if I choose "Barban, Croatia" ( [login to view URL] ) and there is no house listed in that city, as a result it gives just the map of the world ( [login to view URL] ). And that's NOT fine because the system only looks for the cities added in Worpress list of cities. So basically, I would like to change the "MAIN PAGE SEARCH's" function from "search_location" to "geolocation-search", like on Advanced search page. 2) Under my Admin WP account, I can set all the "features and amenities" located in a House for rent. ( [login to view URL] ) All that is written here is later shown as an option which the Subscriber (front end user) can opt for during the process of inserting a new House ( [login to view URL] ) . But when having a look at the page of that property, in the end I get ALL the features bundled in one place ( [login to view URL] ) and it looks not nice and confusing for the end user. No one knows where the KITCHEN features begin and where is the end. So I tried sifferent ways to make SEGMENTS of that list, like here ( [login to view URL] ) where I have tried to add the "---" lines to divida a bit the KITCHEN form POPULAR AMENITIES. The "----" lines are not show on the WEB page itself. What I'm trying to accomplish is: 1) to have a <br> break in the options ( [login to view URL] ) so the new segment/group beginns in a new line and not to be like here ( [login to view URL] ). I've tried to be clear as much I was able, so if something is not understood please contact me.. Thank you!
