Configure the Rich Text and Title Fields

This article explains how to configure the Rich Text and Title fields, the differences between them, and how they differ from the Key Text field.

What are the Rich Text and Title fields?

The Rich Text and Title fields are both customizable text fields. The only difference is that the Title field, as its name says, only allows heading elements as formatting options.

Both fields return an array in the API response. The arrays contain nested elements that specify their content and formatting and can be parsed with the utilities in Prismic's various development kits.

To learn how to render Rich Text and Titles, see the documentation for your framework or technology.

Rich Text vs. Key Text

The Key Text field has no formatting options. It returns a simple string in the API response. This makes the Rich Text field much more complex and configurable.

Elements and styles

These are all the elements and styles available for the Rich Text field. Note that for the Title field, only the heading elements and custom labels are available.

Heading elements (h1, h2, h3, h4, h5, h6)
Normal text paragraph
Strong or bold text
Emphasized or italic text
Preformatted text
Inline hyperlink to the web, to a document, or a media item
Image
Embed to a service URL supporting oEmbed
Unordered list
Ordered list
Right-to-left text
Custom labels

Custom labels

For special formatting in your Rich Text or Title fields, you can add custom formatting by using labels. For example, the prismic-dom kit for developing Prismic apps with JavaScript will, by default, render a custom label as a <span> with a class of the label's name.

This is an advanced configuration that can only be set up in the JSON editor.

Here is an example of a Rich Text field with the label options “right-align” and "center-align":

Copy

 "example_rich_text": {
   "type": "StructuredText",
   "config": {
     "single": "paragraph",
     "label": "Rich Content",
     "placeholder": "Rich Content",
     "labels": ["right-align", "center-align"]
   }
}

Rich Text field configuration

The Rich Text field allows content writers to edit rich content with standard formatting options, such as bold, italics, headings, and lists.

The visual builder

You'll see all these available options when configuring a Rich Text field, as well as the Field name, API ID, and Field placeholder.

JSON model

The following table displays the JSON configuration options available in the JSON editor.

If the 'Allow multiple paragraphs' option is unchecked in the visual builder, then "multi" will change to "single" in the JSON editor.

If neither "multi" nor "single" are specified in the config object, then the field will allow multiple paragraphs and include all the available formatting options.

    "single": "paragraph, strong, em",
    "label": "Quote",
    "placeholder": "Enter a quote..."
  }
}

API response example

Here is an API response example of a Rich Text field with the API ID of example_rich_text:

Copy

"example_rich_text": [
  {
    "type":"paragraph",
    "text":"Lorem ipsum dolor sit amet, consectetur adipiscing elit.",
    "spans":["..."]
  }
