File Set Selector Attribute for Express Entries in 9.X

Developing with Concrete
1

I am using Express to build and manage data entries for much of the content for a project I’m working on. I would like to be able to add a File Set selector as a Data Object attribute. Currently, it looks like this would need to be set up as a custom attribute type. How would I go about doing that?

Additionally, I think it could be useful to have a file folder selector available as an attribute as well.

Unless I’m misunderstanding, go to Dashboard > Express, select your data object, go to Attributes and Add Attribute choosing Image/File as the type.

Also in Dashboard > System & Settings > Attributes > Types you can select which site object types have Image/File enabled.

Is this what you meant?
