Combine "always show all" and ability to add own option

I expected select fields with a fallback for the user to add their own option to be able to function like Google Forms:

This basically combines two options present in OpnForms now, but that cannot be activated at the same time: “Allow respondent to create new options” + “

Always show all select options”. I think this is more intuitive than a drop-down or a separate field visible when “other” is selected.
