Check out the Introduction to Dashboards article to understand the basics of working with widgets.
The Section Heading widget is one of the simplest - yet powerful features of dashboards. They allow you to organize your dashboards into sections. Drag and drop widgets based on logical order and make it easy on your team members to find what they're looking for.
Remember: Ugly dashboards are soooo 2010. Take the time to make yours look great!
To get started, add the widget and click + Add Widget. Select Section Heading, add a name, and drag and drop anywhere on your dashboard. That's it!
