input.enum()

Adds a dropdown setting whose choices are the members of an enum you declare. It returns the chosen member, so the script can compare it with the members directly. Each member's title, the text after `=` in the enum declaration, is what the reader sees in the dropdown. `options` can limit the dropdown to some of the members.

                input.enum(const  defval, const string title, const  options, const string tooltip, const string inline, const string group, const bool confirm) → input enum
