Keep designation available but remove prominent form placement

Open Online Giving → Campaigns or Online Giving → Forms, select the campaign or form, then go to Giving Experience → Form Settings & Display → Designation Configuration.

In the form’s Designations controls, turn off Feature Above Dropdown for the designation you want to keep available in the dropdown. Pinning is separate: it fixes a designation at the top of the dropdown, so unpin it as needed. Use the offered ordering controls to rearrange featured items and preview the form. Do not delete or disable the designation merely to remove prominent placement; synced groups can restrict local changes.
