Document preview

A form element to select files.

Configurable properties

• Title: Title displayed on top of the file picker. Can either be an expression, plain text, or templating syntax.
• Document reference: Data used to render the documents. This can only be an expression. The resulting value must have the following structure:

[
  {
    "documentId": "u123",
    "endpoint": "https://api.example.com/documents/u123",
    "metadata": {
      "fileName": "Document.pdf",
      "contentType": "application/pdf"
    }
  }
]

note

When previewing documents that were uploaded via Filepicker in Tasklist, document references are handled automatically:

• Modifying the document’s metadata after upload may prevent the preview from working correctly.
• To use Camunda's document service without Filepicker, you must include the contentHash, endpoint, and documentId values.

• Hide if: Expression to hide the file picker.
• Max height of preview container: A number which will define the maximum height of each document preview. Any document with a bigger height will display a scroll bar.

Refer to document handling for additional details and limitations.
