Editor toolbars

# Main editor toolbar

The toolbar is the most basic user interface element of CKEditor 5 that gives you convenient access to all its features. It has buttons and dropdowns that you can use to format, manage, insert, and change elements of your content.

# Demo

Below is a sample toolbar with a basic set of features. Toolbar items can be easily added or removed. Read on to learn how to do that.

# Basic toolbar configuration

The toolbar offers a flexible arrangement, achieved through configuration. Please note, that using CKEditor 5 Builder makes this task significantly easier.

The following example may give you a general idea:

ClassicEditor
    .create( document.querySelector( '#editor' ), {
        // ... Other configuration options ...
        toolbar: [ 'undo', 'redo', 'bold', 'italic', 'numberedList', 'bulletedList' ]
    } )
    .catch( error => {
        console.log( error );
    } );

# Separating toolbar items

You can use '|' to create a separator between groups of toolbar items. This works in both the basic and extended configuration formats.

Below you can find an example of a simple toolbar with button grouping. The group separators ('|') set in the configuration help organize the toolbar.

# Extended toolbar configuration format

There are two available toolbar configuration formats:

Basic:

toolbar: [ 'bold', 'italic', '|', 'undo', 'redo', '|', 'numberedList', 'bulletedList' ]

And extended:

toolbar: {
    items: [ 'bold', 'italic', '|', 'undo', 'redo', '|', 'numberedList', 'bulletedList' ]
}

You can use the extended toolbar configuration format to access additional options:

toolbar: {
    items: [
        'undo', 'redo',
        '|',
        'heading',
        '|',
        'fontfamily', 'fontsize', 'fontColor', 'fontBackgroundColor',
        '|',
        'bold', 'italic', 'strikethrough', 'subscript', 'superscript', 'code',
        '|',
        'link', 'uploadImage', 'blockQuote', 'codeBlock',
        '|',
        'bulletedList', 'numberedList', 'todoList', 'outdent', 'indent'
    ],
    shouldNotGroupWhenFull: false
}

• items – An array of toolbar item names. Most of the components (buttons, dropdowns, etc.) that you can use as toolbar items are described in the Features section. A full list is defined in editor.ui.componentFactory and can be listed using the following snippet: Array.from( editor.ui.componentFactory.names() ). Besides button names, you can also use the dedicated separators for toolbar groups ('|') and toolbar lines ('-').

• removeItems – An array of toolbar item names. With this setting, you can change the default toolbar configuration without the need to define the entire list. You can specify a couple of buttons that you want to remove instead of specifying all the buttons you want to keep. If, after removing an item, the toolbar will have two or more consecutive separators ('|'), the duplicates will be removed automatically.

• shouldNotGroupWhenFull – When set to true, the toolbar will stop grouping items and let them wrap to the next line when there is not enough space to display them in a single row. This setting is false by default, which enables item grouping.

The demo below presents the “regular” toolbar look with shouldNotGroupWhenFull set to false. If there are more toolbar items than can fit in the toolbar in the current display width, some items get hidden. You can access them by clicking the show more items button .

# Multiline (wrapping) toolbar

In the extended toolbar configuration format, it is also possible to arrange toolbar items into multiple lines. Here is how to achieve this:

• Set the shouldNotGroupWhenFull option to true, so items will not be grouped when the toolbar overflows. They will wrap to the new line instead.
• Additionally, you can use the '-' separator inside the item list to set the breaking point explicitly.

toolbar: {
    items: [ 'bold', 'italic', '|', 'undo', 'redo', '-', 'numberedList', 'bulletedList' ],
    shouldNotGroupWhenFull: true
}

# Automatic toolbar wrapping

When you set shouldNotGroupWhenFull to true, by default the toolbar items are automatically wrapped into a new line once they do not fit the editor width. The mechanism is automatic and only wraps excess items. Notice that while the toolbar group separators '|' are preserved, the groups may be split when they overflow.

toolbar: {
    items: [
        'undo', 'redo',
        '|',
        'heading',
        '|',
        'fontfamily', 'fontsize', 'fontColor', 'fontBackgroundColor',
        '|',
        'bold', 'italic', 'strikethrough', 'subscript', 'superscript', 'code',
        '|',
        'link', 'uploadImage', 'blockQuote', 'codeBlock',
        '|',
        'alignment',
        '|',
        'bulletedList', 'numberedList', 'todoList', 'outdent', 'indent'
    ],
    shouldNotGroupWhenFull: true
}

See how it works in practice. Play with the browser window width to see how the buttons behave when the toolbar gets wrapped into multiple lines.

# Explicit wrapping breakpoint

Setting an explicit break point in the toolbar configuration with '-' lets you create your own predefined multiline toolbar configuration. Toolbar items will then be grouped and put in lines as declared in the configuration.

toolbar: {
    items: [
        'undo', 'redo',
        '|', 'heading',
        '|', 'fontfamily', 'fontsize', 'fontColor', 'fontBackgroundColor',
        '|', 'bold', 'italic', 'strikethrough', 'subscript', 'superscript', 'code',
        '-', // break point
        '|', 'alignment',
        'link', 'uploadImage', 'blockQuote', 'codeBlock',
        '|', 'bulletedList', 'numberedList', 'todoList', 'outdent', 'indent'
    ],
    shouldNotGroupWhenFull: true
}

# Grouping toolbar items in dropdowns (nested toolbars)

To save space in your toolbar or arrange the features thematically, you can group several items into a dropdown. For instance, check out the following configuration:

toolbar: [
    {
        label: 'More basic styles',
        icon: 'threeVerticalDots',
        items: [ 'strikethrough', 'superscript', 'subscript' ]
    },
    // More of toolbar's configuration.
    // ...
]

It will create a “Basic styles” dropdown with a three vertical dots icon containing the additional basic text styles buttons set. You can test it in the demo below along with a few more toolbar dropdowns.

# Customization

You can customize the look of the dropdown by configuring additional properties, such as the icon, label, or tooltip text.

# Displaying the label

You can control the way the UI element is displayed. For instance, to hide the icon and to display the label, you can use the following configuration:

{
    label: 'Basic styles',
    // Show the textual label of the dropdown.
    // Note that the "icon" property is not configured and defaults to three dots.
    withText: true,
    items: [ 'bold', 'italic', 'strikethrough', 'superscript', 'subscript' ]
}

Note: The label will also automatically show up if the icon is false (learn more).

# Changing the icon

You can use one of the icons listed below for your dropdown:

Icon name	Preview
'threeVerticalDots' (default)
'alignLeft'
'bold'
'importExport'
'paragraph'
'text'
'plus'
'dragIndicator'
'pilcrow'

• The default icons are loaded from the ckeditor5-core package.
• If no icon is specified, 'threeVerticalDots' will be used as a default.
• If icon: false is configured, no icon will be displayed and the text label will show up instead.
• You can set a custom icon for the dropdown by passing an SVG string.

Here is an example:

toolbar: [
    'undo', 'redo', '|',
    {
        // This dropdown uses a default icon because none was specified.
        label: 'Fonts',
        items: [ 'fontSize', 'fontFamily', 'fontColor', 'fontBackgroundColor' ]
    },
    '|',
    {
        label: 'A drop-down with a custom icon',
        // If you want your icon to change the color dynamically (for example, when opened)
        // avoid fill="..." and stroke="..." styling attributes.
        // Use solid shapes and avoid paths with strokes.
        // eslint-disable-next-line max-len

        items: [ 'bold', 'italic', 'strikethrough', 'superscript', 'subscript' ]
    },
    '|',
    {
        // A "plus" sign icon works best for content insertion tools.
        label: 'Insert',
        icon: 'plus',
        items: [ 'uploadImage', 'insertTable' ]
    },
    '|',
    {
        // This dropdown has the icon disabled and a text label instead.
        label: 'Lists',
        icon: false,
        items: [ 'bulletedList', 'numberedList', 'todoList' ]
    }
],

And here is the effect:

# Customizing the tooltip

By default, the tooltip of the button shares its text with the label. You can customize it to better describe your dropdown and make it more accessible by using the tooltip property:

toolbar: [
    {
        label: 'Others',
        tooltip: 'Basic formatting features',
        items: [ 'bold', 'italic' ]
    },
    '|',
    'undo', 'redo'
]

# Listing available items

You can use the following snippet to retrieve all toolbar items available in your editor:

Array.from( editor.ui.componentFactory.names() );

# Adding a custom button

Refer to the step-by-step tutorial to learn how to build a custom plugin, register its button, and add it to the toolbar configuration.

# Decoupled editor

When using the Decoupled editor, you will need to insert the menu bar in a desired place yourself. The menu bar HTML element is available under the editor.ui.view.toolbar.element property.

    <div id="toolbarContainer"></div>
    <div id="editor"><p>Document content.</p></div>

DecoupledEditor
    .create( document.querySelector( '#editor' ), {
        // ... Other configuration options ...
        toolbar: [ 'undo', 'redo', 'bold', 'italic', 'numberedList', 'bulletedList' ],
    } )
    .then( editor => {
        document.querySelector( '#toolbarContainer' ).appendChild( editor.ui.view.toolbar.element );
    } );

# Balloon toolbar

A ballon toolbar is a special instance of the main toolbar, available in the Balloon and ballon block editors. Instead of being fixed to the editing area, it pops up when the user selects some content and provides a toolset for editing as pictured below.

# Block toolbar

The block toolbar provides an additional configurable toolbar on the left-hand side of the content area, useful when the main toolbar is not accessible (for example in certain layouts, like balloon block editor).

# Demo

The great things you learn from traveling

Like all the great things on earth traveling teaches us by example. Here are some of the most precious lessons I’ve learned over the years of traveling.

Appreciation of diversity

Getting used to an entirely different culture can be challenging. While it’s also nice to learn about cultures online or from books, nothing comes close to experiencing cultural diversity in person. You learn to appreciate each and every single one of the differences while you become more culturally fluid.

# Additional feature information

To access the block toolbar, you need to click the button with braille pattern dots icon on the left-hand side of the content area (the gutter). The button appears next to the selected block element (for example, a paragraph), following the caret as the user edits the content and navigates the document.

The icon is also a handle to drag blocks of content around the editor. Click a heading in the demo above and drag it all the way down between the following paragraphs to see this functionality in action.

The block toolbar complements the balloon editor type where it falls short, for example when you must insert some content (like an image), but the selection is collapsed, so you cannot access the toolbar. It can, however, be added to any type of editor and configure accordingly (see below).

See the balloon block editor example page, too.

# Block toolbar installation

To add this feature to your editor, add the BlockToolbar to your plugin list and configure the feature using the blockToolbar property:

import { BlockToolbar, HeadingButtonsUI, ParagraphButtonUI } from 'ckeditor5';

BalloonEditor.create( document.querySelector( '#editor' ), {
	licenseKey: '<YOUR_LICENSE_KEY>', // Or 'GPL'.
	plugins: [ BlockToolbar, ParagraphButtonUI, HeadingButtonsUI, /* ... */ ],
	blockToolbar: [
		'paragraph', 'heading1', 'heading2', 'heading3',
		'|',
		'bulletedList', 'numberedList',
		'|',
		'blockQuote', 'uploadImage'
	],
	toolbar: [ /* ... */ ]
} )
.then( /* ... */ );

# Block toolbar configuration

The content of the block toolbar can be defined using the blockToolbar configuration. It is similar to the regular toolbar UI items list.

blockToolbar: {
    items: [
        'bold',
        'italic',
        'link'
    ]
}

See the installation instructions for a more advanced example.

To adjust the position of the block toolbar button to match the styles of your website, use the CSS transform property:

.ck.ck-block-toolbar-button {
    transform: translateX( -10px );
}

If you plan to run the editor in a right–to–left (RTL) language, keep in mind the button will be attached to the right boundary of the editable area. In that case, make sure the CSS position adjustment works properly by adding the following styles:

.ck[dir="rtl"] .ck-block-toolbar-button {
    transform: translateX( 10px );
}

You can use the shouldNotGroupWhenFull configuration option to prevent automatic items grouping in the block toolbar.

You can also change the current default toolbar icon 'dragIndicator' by choosing predefined icon from icon list using the icon option or by passing a SVG string:

blockToolbar: {
  items: [ /* ... */ ],
  icon: 'pilcrow'
  // or
  // icon: '<svg xmlns="http://www.w3.org/2000/svg" height="24" viewBox="0 -960 960 960" width="24">' +
  // '<path d="M120-240v-80h720v80H120Zm0-200v-80h720v80H120Zm0-200v-80h720v80H120Z"/></svg>'
},
toolbar: [ /* ... */ ]

You can provide a custom toolbar button icon by passing an SVG string.

# Feature-specific toolbars

Some features also sport their own dedicated toolbars. In the demos on this page, you can see the image toolbar or the table toolbars when you use the respective features. You will find all information about these toolbars in the respective feature guides.
