Collection List by Category

Design help CMS

I have to create a sidebar like in this page: Web design lessons | Webflow University
I have the “Lesson” Collection with those fields:

  • title: “Intro to HTML”
  • category: “Getting starte”

How Can I show all titles groupping by their category?
The category name should be a H3 and titles nested inside.

Here is my public share link: LINK
