HTML field tags

HTML is a universal tool for building dynamic PDF forms with ease. Using custom tags like <text-field>, <signature-field>, and other 9 field types. These tags, coupled with the style attribute, enable developers to precisely define the width and height of form fields. For instance, utilizing HTML tags within your HTML structure grants you granular control over each element's positioning and dimensions. This level of customization ensures that the final form aligns perfectly with your design requirements.

HTML field tags can contain the following attributes:

  • name: Name of the field in the template.
  • role: signer role name. Specify different names in case the document contains multiple signing parties with their own set of fields.
  • default: default field value to be used in the template.
  • required: set false to make the field optional and skipable. true by default.
  • readonly: set true to make it impossible for the signer to edit the pre-filled field value. false by default.
  • option: option value for multi-select and radio field types. Fields with the same name are grouped into radio and multi-select groups with passed option values.
  • condition: `FieldName:value` to show the field only if the condition is met for the value in other field. Pass only `FieldName` to set a condition for a non-empty field.
  • options: comma separated list of options for select field type.
  • pattern: HTML field validation pattern string based on https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/pattern specification.
  • format: date field format, MM/DD/YYYY is used by default.
  • font: font name to be used in the field. Can accept "Times", "Helvetica" or "Courier" PDF default fonts to be used for the field font.
  • font-size: font size of the text value. This attribute is optional, default font size will be calculated based on the field height by default.
  • color: "blue" or "red" color of the text value or signature. This attribute is optional, default "black" color is used when not specified.

Creating HTML layout

To begin crafting PDF document templates, start by creating a structured HTML, incorporating these custom field tags. Use Chrome print preview feature to get a real-time visualization of the document appearance as a PDF.

Custom CSS, whether embedded inline or linked externally, can be used to refine the visual design of the document. 

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
