Building an interactive event calendar in Drupal 10 using the FullCalendar View module

Managing events on a website often starts simple, but soon you realize a basic list doesn’t cut it. Users want to see what’s coming up, not read through endless entries. A well-designed calendar makes that possible.

The FullCalendar View module brings that experience to Drupal 10. It turns your date-based content like events, bookings, training sessions, and editorial schedules into an interactive, polished calendar powered by Views.

In this blog, I’ll walk you through how to set up the FullCalendar View module in Drupal 10, configure a calendar using Views, and customize its behavior.

What is FullCalendar View?

FullCalendar is a popular JavaScript library that provides:

• Month, Week, Day, and List navigation
• Drag-and-drop interactions
• Clickable events
• Fully responsive UI
• Customizable colors and themes

The FullCalendar View module integrates this JavaScript library with Drupal Views, allowing you to visually render event-based content without custom coding.

Creating the Event content type

Before building your calendar, you need a content type that stores your event information.

Create a new content type

Navigate to:
Structure → Content types → Add content type

Name it “Event” (or anything relevant). Add a description if it helps your editors.

Front-End customization

Front-end customization allows you to adjust the appearance and behavior of the calendar to match your site’s design and functionality needs. You can modify styles to control colors, spacing, and layout. Template overrides can be used to change the HTML structure generated by the calendar. JavaScript customization enables you to enhance interactions such as clicks, hovers, or other event-driven behaviors. All these adjustments help create a calendar that aligns visually with your theme and provides a smooth user experience.
