I built a range slider with the help of noUiSlider and i´m wondering if this could be setup like a checkbox with "Filter"-Variation in Searchform View. Here is explained that a special event is fired when a new value is set. Is there a way to make a search when this event is triggered?
If you build the slider so that it is a field, then you can include it in the Search Form. You can use the developer to create the layout, then add the logic that you want.
