title: Dropdown component on header toolbar of fullcalendar in react js without jquery
body: <p>I am using fullcalendar in react js and want to display dropdown in it's header toolbar. I have a separate component for dropdown and want to integrate it in the header. Is there any way to do that without using jquery I checked their documentation but there is nothing like that. We can create only custom buttons and can't even pass any tags in those buttons. There have just limited options .</p>
