FileMaker Pro, beyond your normal join table, offers a unique method of storing collections, or groups, of items. You can do this with what is called a multi-key field. This isn’t to be confused with a compound-key, which is a primary key composed of multiple different values.
Using a multi-key field we can store a collection of custom functions within our Custom Function database. This makes it possible to start the process of collecting groups of functions together and then adding a feature so we can copy them as a group.
Of course, the trick to adding any complex functionality is to make it easy for the user while staying maintainable for us as the developers. This will be done within a standard FileMaker Popover layout object.
This video walks through the process and parts of adding a grouping or collections based feature. While we’re adding it within the context of custom functions, this is a feature you’ll find using over and over again no matter what the database is about.
