Describe the feature

I'd like a string field in a form struct to be rendered as a Chooser.

I've had a quick dig through the code and it doesn't seem possible as things stand. Essentially this equates to a larger feature request, that form field widgets can be specified via struct tags where appropriate (and in this case, enum values provided).

Code below is indicitive of what I'd like to be possible.

Relevant code

type MyStruct struct {
	SomeField string `widget:"chooser" values:"foo,bar,baz"`
}

form := core.NewForm(someFrame)
form.SetStruct(&MyStruct{}) // SomeField is rendered as a Chooser with available values of foo, bar, baz
