Hi, which kind of content can I add to the course sidebar? I see that I can use the shortcode [section]text[/section] in order to add some text. Can I add something more between this shortcode? for example, some testimonial shortcode (although I’ve tried it and it not looks so good), some contact form sortcode, etc… Or what do you recommend to add here? What is the main purpose of this section. Maybe just some information text?
