Thank you for your quick response.
I’d like to change the value from outside the component. That works fine with all other input types in f7-react, if your state is managed by mobx / mobx-react. However, mobx / react does not seem to trigger the update cycle for the change in value of the datepicker. That is why I want to update the value manually. But, I can’t seem to get the calendar instance.
I tried overriding the input value using Dom7, but that does not change the highlighted value in the calendar popover / modal sheet when I open the calendar again.
