Ajax-based range slider. Take 3. Front-end games.
SimpleRangeInput widget for faceted ranges invented with some jquery functions. It concats two text inputs and redirects page to constructed url.
'dynamic' queries will be marked as selected anyway. 'deselect_url'  used for the range form 'action'. Also there are no proper form validation at all as well as ajax.
It was a bit tricky to include additional javascripts for partial templates.
