How can I define site wide collections of types, and refer to the them in blueprints for a page type?
For example, I want to create a single list of a custom type called 'Technology'. A 'Technology' object has two properties: a CSS class and a title. I'd like to create a list of these classes in a single place, then use that list as a source for a multiselect field in a page template - ie I want to several technologies and iterate through the selected ones in a Twig template.
Is this possible? If so how would I go about it?
