You can use a button to create one or more child instances. If you know you will only be creating a single child instance for any specific form type, then you should use the Show Form button object. The Show Form button can behave in different ways as defined in its properties on the Properties bar.
See the Show Form Button Properties topic for a more detailed explanation of the properties of this button object.
