Paged grid

system:grid

Builds only the cells of the current page, and computes the page capacity from the column count and the maximum rows.

Nodes are written into the body or children of a resource pack card template. Besides their own fields, all nodes share id, style, when, unless and repeat; see Common node fields.

      "text": "{{entries.*.name}}"
    }
