A big thank you for the work done by the community.
I'm using the Owncloud solution for many years and of course I switched to NextCloud.
Through my intermediary, my clients and my students are exploiting this solution.
I was asked to sort the events according to a list of categories.
This feature exists under Lightning.
This is made possible by the "CATEGORIES" field existing in "VCALENDAR".
Is it possible to implement this feature in the Web interface of the NextCloud Calendar application?
