The following documentation goes through the process of editing Custom Widgets. This applies to Custom Widgets and not System Widgets as they are customized by going into the clicking the Customize icon rather than the Edit icon. To learn about customizing widgets please visit the Customizing Widgets tutorial.
Enter the course you would like and click on Edit Course button on the navigation bar.
From the Custom Widgets tab, click the Edit icon for your widget.
Use the three tabs and their options to edit your widget and click Save after any changes made.
