I'm using the Contact Form 7 Calendar "plugin plugin", but I can't figure out how to make the date field required. The syntax is
[datetimepicker your-label], and in the parent plugin (Contact Form 7), you would just put an asterisk in, like
[datetimepicker* your-label] but this doesn't work with the calendar widget... Of course, I could always style it in CSS to appear as if its required, but I kinda need the validation there. I've looked in the plugin's documentation, but this isn't covered, and the author is not responding on the WP Support Forums.
