Query Loop on Form Field (Drop Down/Select)

Subject: Form Fields (Select/Drop Down) that list my “Services”, which are entered as a Custom Post Type (Services).

Example: Services (service one, service two…)

Form: Select (Drop Down) Field > Query List of “Services”… so we do not have to manually enter the services.

I am not sure if I’m overlooking something… seems like this should be integrated already.
