Hello,
Sometimes, filters can take too much place on screen, especially on laptop. Therefore, it can be useful to fold the filter object. As of today, we use the QS Side Menu Extension (https://developer.qlik.com/garden/59a7cf3c074edfb580b4b968 ) but I believe it should just be an option for classic, supported, filter object.
Best regards,
