How to Use the Rich Editor

Last updated: 2026/04/24

This page explains how to operate the rich editor and its features.

About the Rich Editor

The rich editor is an editor that allows you to input formatted text.
You can create content with a high degree of freedom, including headings, bold text, links, and image insertion. The created content can be retrieved as HTML via the API.

The rich editor is also known as a WYSIWYG editor and is commonly used in other CMSs and tools. The basic operation feels similar, so those who are familiar with it can quickly master it.

Information

When using the rich editor, it is assumed that you will directly input text in the management screen. Please note that while the submission format may be somewhat maintained when pasting text created in Word or HTML data, we cannot guarantee that all submitted content will be saved correctly.

Headings and Paragraphs

h1 to h5 and p tags are supported.
h1 to h5 will have a hashed string assigned as the id. (This means that the id remains fixed as long as the text is not changed.)

<h1 id="h634aaf8fde">Heading 1</h1>

Using the assigned id, it is possible to generate a table of contents on the frontend.
For more details, please refer to the article below.

Line Breaks and Paragraphs

Pressing Enter in the editor creates a new paragraph.
Pressing Shift + Enter inserts a line break.

// Paragraph
<p>Pressing Enter creates</p>
<p>a new paragraph.</p>

// Line Break
<p>Pressing Shift + Enter inserts<br>a line break.</p>

The difference between line breaks and paragraphs is visually indicated by spacing in the editor screen.

You can also select colors defined in the API settings in advance.

You can specify a filename and language for the code block.
If specified, the response changes as follows.

  <pre>
    <code class="language-javascript">const greeting = "Hello microCMS!";\nconsole.log(greeting);</code>
  </pre>
</div>

You can input a table.

You can add rows and columns, merge and split cells, and set the first row and column as headers.

Data is represented using the table tag.

    <tr>
      <th colspan="1" rowspan="1">
        <p>Company</p>
      </th>
      <th colspan="1" rowspan="1">

      </th>
    </tr>
    <tr>
      <td colspan="1" rowspan="1">
        <p>microCMS</p>
      </td>
      <td colspan="1" rowspan="1">
        <p>Tokyo</p>
      </td>
    </tr>
  </tbody>
</table>

List

Text is enclosed in ul and li tags.

<ul>
  <li>Apple</li>
  <li>Orange</li>
</ul>

Lists can be nested. If nested, the response will look like this.

    <ul>
      <li>Tokyo</li>
      <li>Osaka</li>
      <li>Saitama</li>
    </ul>
  </li>
  <li>America</li>
</ul>

If the structure becomes deeply nested, there is a possibility of errors occurring due to database storage constraints. The number of nestings that can be configured varies depending on the structure, so if you have any questions, please contact us via the chat box in the bottom right corner.

Numbered List

The text will be enclosed in ol and li tags.

<ol>
  <li>Account Registration</li>

How to Migrate from the Old Rich Editor to the Rich Editor

The old Rich Editor is treated as a separate field due to its different internal data structure.
Therefore, switching from the old Rich Editor requires manual migration work.
