You are able to link to a specific toggle on your page. One possible use for this is to link one of your icons at the top of your page to a toggle of related resources.
To get this toggle-specific link:
Navigate to the main page for your course (meaning you are not viewing a specific activity, the participants list, question bank, etc)
Add #section-___ to the end of the URL. If you are wanting the link to open section 2, you will add #section-2 to the end of the URL as shown in the image below
