How to Add Sidebar Widgets
1. What are Sidebar Widgets

Sidebar Widgets enable you to add extra components/sections to the right of the online payment/donation form. You can select the items you wish to show and the order you wish to show them.
2. Navigate to the Merchant Facility tab
The Merchant Facility tab can be found within the Payments2Us menu (Top right picklist in Salesforce - Select Payments2Us), or it can be found under the "More" at the end of the tabs. (In Salesforce Classic - It can be under the "+" at the end of the tabs)
Once you have clicked on the Merchant Facility Tab, select the appropriate List view (Example- “All Merchant Facilities”) and click into Merchant Facility you wish to update.
