Form Fields

DocPayload supports interactive form fields as inline tags, rendered cross-format:

• PDF: emitted as AcroForm fields, fillable in any standard PDF reader (Adobe Reader, Foxit, browser viewers).
• DOCX: emitted as Structured Document Tag (SDT) content controls, fillable in Microsoft Word and compatible editors.

The same template definition produces both — recipients on either format see the same set of editable fields.

Seven field types are supported: text input, text area, checkbox, radio button, choice (dropdown), list box, and date picker.

{ "p": "Full Name: [textfield, fullName, John Doe, 200|20]" }

Quick start

A minimal interactive form:

{
  "content": [
    { "h2": "Application" },
    { "p": "Full Name: [textfield, fullName, , 220|22]" },
    { "p": "Email: [textfield, email, , 250|22]" },
    { "p": "Department: [choicefield, dept, Engineering|Sales|Operations, 0, 180|22]" },
    { "p": "[checkbox, agree, false, 14|14] I accept the terms and conditions" },
    { "p": "Notes:[br][textarea, notes, , 400|80]" }
  ]
}

Recipients open the document in any compatible viewer — Adobe Reader, Foxit, or browser PDF viewers for PDF; Microsoft Word, LibreOffice, or Google Docs for DOCX — and type / select directly.
