Hi Danyz, in answer to your questions:
1. Yes our themes are customizable. They are not encrypted, so you are free to make changes as you wish. You may find some of the documentation on our
AppThemes developer center useful to see how you can make customizations. We recommend the use of child themes so that you don't lose all of your modifications in the process of an update.
2. No, there is no limit to the number of categories you can have, but you may wish to note specifically with ClassiPress there is no built in importer which means importing these in bulk may involve a plugin and possibly some additional knowledge of mysql admin in order to do this in bulk. Otherwise, it's a manual process of adding them. In Vantage there is a .csv importer built into the theme for importing listings.
3. As above, applicable to ClassiPress
4. What you see in the category view is as you see on the
Vantage demo, so again any change to this would require customization on your part. You can however create custom listing forms from within the
Vantage admin to determine which fields you wish to add for the form for that specific category.
5. This would require some customization of the default theme, as the existing search from the main page is for the type and location only. There is a "Refine Search" field which appears in the sidebar when you search a location (as you can see
here on the Vantage demo), so you could potentially work with that.
I hope this information helps. Thanks.
