React Event calendar Event Search Popup

Use the available real estate in the calendar header to add event search. With the templating capabilities of the header you can easily add a search box and use a separate agenda instance to show the search results. This example is relying on a single API endpoint for getting the data onto the primary calendar view and also for getting the filtered data based on the search terms.

Events can be filtered in real time so using an agenda view for the search results is an easy choice. It provides all the necessary styling and advanced features that you might need to customize the experience.

Alternatively, search can be implemented in a sidebar next to the event calendar using a similar search box with an inline agenda instead of a dropdown.

Search events in real time from the event calendar header — results appear in an agenda-style popup as you type, grouped by date.
