How to display files in a grid with details?

but my problem is that I can't create new columns with more information

Can you please elaborate.

When I write a new a!gridLayoutHeaderCell and I map a!richTextDisplayField inside the content of my a!gridRowLayout I recieve this error:

load(
            local!data: {
              {
                id: 1,
                folderId: 4768/* Folder ids*/

              },
              {
                id: 2,
                folderId: 4947/* Folder ids*/

              }
            },
            a!gridLayout(
              label: "Documents",
              labelPosition: "ABOVE",
              headerCells: {
                a!gridLayoutHeaderCell(
                  label: "Name"
                ),
                a!gridLayoutHeaderCell(
                  label: "Description"
                )
              },

I don't think you would need another forEach in your line 92 if I am right. because you are already doing it for the gridRowLayout. But are you trying to show multiple details in a single row?
