How to create a range slider

One final (final) question, which isn’t a big deal really - and if it’s outside of your support scope, no worries - but what would the most logical way to go about implementing a range slider be? In this case it would be prices, from say $0.00 to the highest price currently available?

That’s not really Kirby related. You might have a look at this JavaScript solution or this polyfill for the HTML input type range.

Or do you mean how to get the values?
