Thanks- I promise I tried but it didn't work for me- I don't have enough experience w the local variables. I'm going to review with a developer to see if we can get it working. ty!

Ah yeah I just realized that pattern doesn't pull data from documents - it actually has hardcoded data. You could use the document() function to find all of the properties that are displayed in that card, but it's a little tricky actually getting the data to show in the right format.

If you want, you could try to plug in something like this expression to replace the current definition for local!documents and it should work:

local!documents: a!forEach(
  items: rv!record['recordType!Saving.fields.{folderId}folderId'],
  expression: a!map(
    name: document(fv!item, "name"),
    description: document(fv!item, "description"),
    uploadDate: datetext(document(fv!item, "dateCreated"), "MMMM d"),
    size: document(fv!item, "size")/1000 & "KB",
    type: a!localVariables(
      local!extension: document(fv!item, "extension"),
      a!match(
        value: local!extension,
        whenTrue: contains({"xls", "xslx"}, fv!value),
        then: "excel",
        whenTrue: contains({"doc","docx"}, fv!value),
        then: "word",
        equals:  "pdf",
        then: "pdf",
        default: "image"
      )
    )
  )
)

This will loop acroos the list of documents and identifiy properties for each document.

Thanks I like the pattern- I'm not very experienced with adjusting local variables- do I replace all of them with ri!record...? I have looked at the "Adapt a Pattern" doc and I'm just clarifying the guidance there. ty

There's also a nice pattern that you can adapt with a list of documents - it's a little more complex, but I like the additional information displayed here: docs.appian.com/.../document-list-pattern.html

I suggest to use a!foreach() on that multiple field to dynamically create a list of a!richtextdisplayfield(). In that field, you add a richtextitem to display the text. These can take a link parameter which allows you to download the document using a documentdownloadlink().

Give it a try.
