This is an extension for the Contao Open Source CMS. If you are not a software developer, please download or install from the Contao Extension Repository.
Using this extension, you can add an image gallery (identical to the content element) to each calendar event.
In Contao 3, this extension is no longer working! Every event can have unlimited content elements by default, including galleries.
After installation, you will see an additional section in every event, where you can add your images. You must also choose the new template event_full_gallery in your event reader frontend module. If you want to show the gallery in other event templates, simply apply the differences.
The Contao Core extension "calendar" must obviously be enabled. There are no other external dependencies.
