DVStudioSegmented<T> class

A set of mutually exclusive options drawn as one control: device width, text alignment, a layout's direction.

For a choice with a handful of values this is the right control, and a free-text field listing the values underneath it — which is what the inspector offered — is the wrong one: it accepts typos and shows nothing.
