The plugins SDK config parameters documentation discusses the various field types available:
type(required): The type of field to offer when editing this parameter (can beboolean,date,date_time,float,integer,string,text,jsonorcolor)
But is it possible to create a dropdown selector (choose from a list of predefined strings, such as ‘Light Mode’ and ‘Dark Mode’) or a multi-select field like is used for the Markdown editor?
In short, I was hoping to be able to specify type string but allow one or more selections from a predefined list.
