Has anyone successfully replaced the date range option with a slider like :https://ghusse.github.io/jQRangeSlider/ ?
Any tips on how to do this? The current method of selecting a start date using a calendar and an end date using a calendar is very old fashioned - it would be great to be able to use a range slider.
No, we have no such feature request yet. But, it can be easily done with custom template.
Current calendar is standard and classic way to choose a date. Your way is more modern, but it can be not clear or uncomfortable for some people.
Also, on server side, you can use search results url as some menu item link, you can modify any menu item link through database _menu table and call search results directly.
