I've created several custom fields (specifically the Field Type "Select" that offer the user predefined options) for my listings. I want to use them as a filter at the site's homepage. For example, I'd like to see at the homepage four filters using exactly the same predefined options that the listings have considering the four new "Select" custom field I've added. Is that possible? If not, how much development would that demand? Thanks in advance for your answer.
Unfortunately there isn't a way to do that with our theme unless you custom code something up. Sorry. If this isn't something you're able to do then you would need to hire a developer for this.
