React Instant Search Availability Dates

Hello, so I’m currently stuck on a problem. What I am trying to do is to implement an Available now filter with a checkbox. All my records currently have a starting date and what I am trying to do is to group all the dates and check if the dates are more than today’s date. So it would be a check box that shows all the current condos where the dates is available. But I could not find a solution for that. Is there something I can do ? I currently use a CustomRefinementList and I do get all the dates but it gets all the dates displayed. My problem is, that, I want to have one checkbox ex: Available Now , and if the user click on it it will return all the condos that the dates are greater than today ?

Thank you for your help :slight_smile:
