Hi Íñigo!
Thanks for coming back to us! 🙂
Let me try to help you with that.
When you say “highlighted”, are you referring to the text excerpt that gets shown for each event? If so, and you want to customize this, the you’d probably want to take a look at this article > https://theeventscalendar.com/the-trouble-with-excerpts/
Does it help? Let me know about it and if you have any other questions.
Also, I noticed you are from Spain, so feel free to reach out to me in spanish if that helps you better explain yourself.
Best,
Victor
