Some of these options are available in the premium version of the plugin.
Make your filter collapsible to toggle its opened / closed state by a click on the title bar.
Initialize in a collapsed state checkbox will put your collapsible filter into an initially collapsed state when the page loads.
Premium version adds the option of displaying your filter as dropdown – with checkboxes, custom icons, color boxes and all the rest of the styling options still available inside of the select box.
Use current active filter as dropdown title option is available for dropdowns with Single item selection filter type. It will set the dropdown title to the selected value whenever the filter is activated, to imitate the behavior of a classical select box.
