RichText Reference Edit

RichText is a component that allows developers to render a contenteditable input, providing users with the option to format block content to make it bold, italics, linked, or use other formatting.

The RichText component is extremely powerful because it provides built-in functionality you won’t find in other components:

  • Consistent Styling in the Admin and Frontend: The editable container can be set to any block-level element, such as a div, h2 or p tag. This allows the styles you apply in style.css to more easily apply on the frontend and admin, without having to rewrite them in editor.css.
  • Cohesive Placeholder Text: Before the user writes their content, it’s easy to include placeholder text that’s already styled to match the rest of the block editor.
  • Control Over Formatting Options: It’s possible to dictate exactly which formatting options you want to allow for the RichText field. For example, you can dictate whether to allow the user to make text bold, italics or both.

Unlike other components that exist in the Component Reference section, RichText lives separately because it only makes sense within the block editor, and not within other areas of WordPress.

Core Blocks Using the RichText Component Core Blocks Using the RichText Component

There are a number of core blocks using the RichText component. The JavaScript edit function linked below for each block can be used as a best practice reference while creating your own blocks.

  • Button: RichText is used to enter the button’s text.
  • Heading: RichText is used to enter the heading’s text.
  • Quote: RichText is used in two places, for both the quotation and citation text.
  • Search: RichText is used in two places, for both the label above the search field and the submit button text.

Example Example

import { registerBlockType } from '@wordpress/blocks';
import { useBlockProps, RichText } from '@wordpress/block-editor';

registerBlockType( /* ... */, {
    // ...

    attributes: {
        content: {
            type: 'string',
            source: 'html',
            selector: 'h2',
        },
    },

    edit( { attributes, setAttributes } ) {
        const blockProps = useBlockProps();

        return (
            <RichText
                { ...blockProps }
                tagName="h2" // The tag here is the element output and editable in the admin
                value={ attributes.content } // Any existing content, either from the database or an attribute default
                allowedFormats={ [ 'core/bold', 'core/italic' ] } // Allow the content to be made bold or italic, but do not allow other formatting options
                onChange={ ( content ) => setAttributes( { content } ) } // Store updated content as a block attribute
                placeholder={ __( 'Heading...' ) } // Display this text before any content has been added by the user
            />
        );
    },

    save( { attributes } ) {
        const blockProps = useBlockProps.save();

        return <RichText.Content { ...blockProps } tagName="h2" value={ attributes.content } />; // Saves <h2>Content added in the editor...</h2> to the database for frontend display
    }
} );
wp.blocks.registerBlockType( /* ... */, {
    // ...

    attributes: {
        content: {
            type: 'string',
            source: 'html',
            selector: 'h2',
        },
    },

    edit: function( props ) {
        var blockProps = wp.blockEditor.useBlockProps();

        return wp.element.createElement( wp.blockEditor.RichText, Object.assign( blockProps, {
            tagName: 'h2',  // The tag here is the element output and editable in the admin
            value: props.attributes.content, // Any existing content, either from the database or an attribute default
            allowedFormats: [ 'core/bold', 'core/italic' ], // Allow the content to be made bold or italic, but do not allow other formatting options
            onChange: function( content ) {
                props.setAttributes( { content: content } ); // Store updated content as a block attribute
            },
            placeholder: __( 'Heading...' ), // Display this text before any content has been added by the user
        } ) );
    },

    save: function( props ) {
        var blockProps = wp.blockEditor.useBlockProps.save();

        return wp.element.createElement( wp.blockEditor.RichText.Content, Object.assign( blockProps, {
            tagName: 'h2', value: props.attributes.content // Saves <h2>Content added in the editor...</h2> to the database for frontend display
        } ) );
    }
} );

Common Issues & Solutions Common Issues & Solutions

While using the RichText component a number of common issues tend to appear.

Placeholder Content Separates from the Input Placeholder Content Separates from the Input

In some cases the placeholder content on RichText can appear separate from the input where you would write your content. This is likely due to one of two reasons:

  1. You can’t have an element with the CSS display property set to inline. You will need to set it to inline-block or any other value.
  2. The position CSS property value for the element must be set to relative or absolute within the admin. If the styles within style.css or editor.css modify the position property value for this element, you may see issues with how it displays.

HTML Formatting Tags Display in the Content HTML Formatting Tags Display in the Content

If the HTML tags from text formatting such as <strong> or <em> are being escaped and displayed on the frontend of the site, this is likely due to an issue in your save function. Make sure your code looks something like <RichText.Content tagName="h2" value={ heading } /> (ESNext) within your save function instead of simply outputting the value with <h2>{ heading }</h2>.

Unwanted Formatting Options Still Display Unwanted Formatting Options Still Display

Before moving forward, consider if using the RichText component makes sense at all. Would it be better to use a basic input or textarea element? If you don’t think any formatting should be possible, these HTML tags may make more sense.

If you’d still like to use RichText, you can eliminate all of the formatting options by specifying the withoutInteractiveFormatting property.

If you want to limit the formats allowed, you can specify using allowedFormats property in your code, see the example above or the component documentation for details.

Disable Specific Format Types in Editor Disable Specific Format Types in Editor

The RichText component uses formats to display inline elements, for example images within the paragraph block. If you just want to disable a format from the editor, you can use the unregisterFormatType function. For example to disable inline images, use:

wp.richText.unregisterFormatType( 'core/image' );

To apply, you would need to enqueue the above script in your plugin or theme. See the JavaScript tutorial for how to load JavaScript in WordPress.
