guideHorizontal line

The HorizontalLine plugin allows inserting a horizontal line into the rich-text editor.

Often known as the horizontal rule, it provides a visual way to separate the content. It may indicate a thematic shift (like a change of topic) between paragraphs or parts of the story or just be a simple graphic separator to help organize the content.

# Demo

Use the editor below to see the horizontal line feature in action.

There are more CKEditor 5 features that can help you organize your document content better:

  • Page break – Divide your document into pages.
  • Document title – Clearly separate the title from the body.
  • Lists – Create ordered (numbered) and unordered (bulleted) lists.

# Installation

npm install --save @ckeditor/ckeditor5-horizontal-line

And add it to your plugin list configuration:

import HorizontalLine from '@ckeditor/ckeditor5-horizontal-line/src/horizontalline';

    .create( document.querySelector( '#editor' ), {
        plugins: [ HorizontalLine, ... ],
        toolbar: [ 'horizontalLine', ... ],
    } )
    .then( ... )

# Common API

The HorizontalLine plugin registers:

  • the UI button component ('horizontalLine'),
  • the 'horizontalLine' command implemented by HorizontalLineCommand.

The command can be executed using the editor.execute() method:

// Inserts a horizontal line into the selected content.
editor.execute( 'horizontalLine' );

We recommend using the official CKEditor 5 inspector for development and debugging. It will give you tons of useful information about the state of the editor such as internal data structures, selection, commands, and many more.
