When gifts with tributes are processed, a new tribute is added with every gift.
When creating the donation form, there are several tribute options. By default, a tribute description is enabled on the form and is required when a tribute name is entered. When processing, this information is automatically selected in the tribute dropbox. If undesired, click the dropbox and select from the list of already created tributes for the constituent. Otherwise a new tribute will be added when the gift is processed.
It is possible to remove the tribute description from the donation form. To do this, edit the part and mark Hide tribute description field.
