I created a section (page) on the website that has sidebar + content. In the left sidebar is a list of pages (links). However, I want each page title to highlight as I scroll down from one topic to the next. How can I do this?
Digitalocean is doing this. They have a menu on the lefthand side and when you click on a topic, the link highlights, and it scrolls down the page to that section. Check it out here. Thanks
