You can refer the data-page in the drop-down source. In the below example, I am populating the cities using the data-page: D_CityList in the drop-down. In your use-case you can create a data-page with the list type (D_GenderValues) which returns the values like (Male, Female) and refer in the gender dropdown and the salutation like MR and MRs on referering the data-page in the Title property.
In my use-case, I have configured the property for display as cityName and property for value as cityID. Property for display is the value that is displayed on drop-down. Property for value is the one which actually stored in the data-base.
