If you're referring to the header drop down menu, you can disable the events functionality within the theme via the Vantage settings, and also use the build in WordPress custom menus option to set the menu to how you'd like. The theme itself doesn't have options to separate listings into cities as such, however you could look at options such as the
Multi-City AV plugin for Vantage which allows users to filter by location, or you could consider a
WordPress multisite setup and have something similar to what you see on
this site from our
customer showcase.
Yes maps will only show the listings that are posted. The Photoshop .psd files are useful for web designers who wish to redesign the layout of the theme, as they contain all of the layout/color/size information for all of the pages used within the theme. You still need knowledge of .css in order to make use of the files. Thanks.
