Hi there Eric,
Thanks for getting in touch with us! I can help you here…
Basically the state of the filter bar depends on the default setting, but if the user collapses or opens the filters that last stat is stored in a cookie and will be respected while the user navigates the calendar. I guess the options here are to change the cookie or trigger the show/collapse button via JavaScript on page load event.
Do you think that might work for you? If that’s the case I can help you with a basic example of this.
Best,
Nico
