To configure a form to save data to custom address fields:
- Click Forms in the top navigation bar.
- Create a new form or select an existing form.
- Click Edit Form in the right-hand side menu.
- Drag in a Street Address widget onto the form from the form fields palette.
- Within the Export Key setting, manually enter the export key to link the address widget with the new custom fields. For this example, the export key would be 'sys:field_emergency_address'. For application-scoped fields, the export key for this example would be 'sys:app_emergency_address'.
