Editor toolbar
The toolbar is the most basic user interface element of the WYSIWYG editor that gives convenient access to all its features. It contains various items like buttons or dropdowns that you can use to format, manage, insert and alter elements of the content.
Toolbar configuration is a strict UI-related setting. Removing a toolbar item does not remove the feature from the editor internals. If your goal with the toolbar configuration is to remove features, the right solution is to also remove their respective plugins. Check removing features for more information.
# Basic toolbar configuration
In the builds that contain toolbars an optimal default configuration is defined for it. You may need a different toolbar arrangement, though, and this can be achieved through configuration.
Each editor may have a different toolbar configuration scheme, so it is recommended to check its documentation. In any case, the following example may give you a general idea:
ClassicEditor
.create( document.querySelector( '#editor' ), {
toolbar: [ 'bold', 'italic', 'link', 'undo', 'redo', 'numberedList', 'bulletedList' ]
} )
.catch( error => {
console.log( error );
} );
# Demo
This is how a simplified toolbar from the snippet above looks in the CKEditor 5 WYSIWYG editor user interface. Toolbar items can be easily added or removed thanks to this configuration.
# Separating toolbar items
You can use '|'
to create a separator between groups of toolbar items. It works in both the basic and extended configuration formats:
Basic:
toolbar: [ 'bold', 'italic', '|', 'undo', 'redo', '|', 'numberedList', 'bulletedList' ]
Extended:
toolbar: {
items: [ 'bold', 'italic', '|', 'undo', 'redo', '|', 'numberedList', 'bulletedList' ]
}
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
You can use the extended toolbar configuration format to access additional options:
toolbar: {
items: [ 'bold', 'italic', '|', 'undo', 'redo', '-', 'numberedList', 'bulletedList' ],
shouldNotGroupWhenFull: true
}
-
items
– An array of toolbar item names. Most of the components (buttons, dropdowns, etc.) which can be used as toolbar items are described under the Features tab. 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 modify the default toolbar configuration without the need of defining 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, toolbar will have two or more consecutive separators ('|'
), the duplicates will be removed automatically. -
shouldNotGroupWhenFull
– When set totrue
, 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 isfalse
by default, which enables items grouping.
The demo below presents the “regular” toolbar look with shouldNotGroupWhenFull
set to false
. If there are excess toolbar items for the display width, the toolbar gets grouped and some of the items are accessible via the clickable “Show more items” (⋮) button.
# Grouping toolbar items in drop-downs (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 config.
// ...
]
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 only, 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' |
- 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 drop-down by passing an SVG string.
Here is an example:
toolbar: [
{
// This drop-down uses a default icon because none was specified.
label: 'Fonts',
items: [ 'fontSize', 'fontFamily', 'fontColor', 'fontBackgroundColor' ]
},
{
// This drop-down has the icon disabled and a text label instead.
label: 'Lists',
icon: false,
items: [ 'bulletedList', 'numberedList', 'todoList' ]
},
{
// A "plus" sign icon works best for content insertion tools.
label: 'Insert',
icon: 'plus',
items: [ 'uploadImage', 'insertTable' ]
},
{
label: 'A drop-down with a custom icon',
// If you want your icon to change the color dynamically (e.g. when opened)
// avoid fill="..." and stroke="..." styling attributes.
// Use solid shapes and avoid paths with strokes.

items: [ 'bold', 'italic' ]
},
'|',
'undo', 'redo'
]
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 (learn more):
toolbar: [
{
label: 'Others',
tooltip: 'Basic formatting features',
items: [ 'bold', 'italic' ]
},
'|',
'undo', 'redo'
]
# 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 totrue
, so items will not be grouped when the toolbar overflows but will wrap to the new line instead. - Additionally, the
'-'
separator can be used inside the items list to set the breaking point explicitly.
toolbar: {
[ 'bold', 'italic', '|', 'undo', 'redo', '-', 'numberedList', 'bulletedList' ],
shouldNotGroupWhenFull: true
}
# Automatic toolbar wrapping
When shouldNotGroupWhenFull
is set 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: [
'heading', '|',
'fontfamily', 'fontsize', '|',
'alignment', '|',
'fontColor', 'fontBackgroundColor', '|',
'bold', 'italic', 'strikethrough', 'underline', 'subscript', 'superscript', '|',
'link', '|',
'outdent', 'indent', '|',
'bulletedList', 'numberedList', 'todoList', '|',
'code', 'codeBlock', '|',
'insertTable', '|',
'uploadImage', 'blockQuote', '|',
'undo', 'redo'
],
shouldNotGroupWhenFull: true
}
See how it works in practice. You may 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: [
'heading', '|',
'alignment', '|',
'bold', 'italic', 'strikethrough', 'underline', 'subscript', 'superscript', '|',
'link', '|',
'bulletedList', 'numberedList', 'todoList',
'-', // break point
'fontfamily', 'fontsize', 'fontColor', 'fontBackgroundColor', '|',
'code', 'codeBlock', '|',
'insertTable', '|',
'outdent', 'indent', '|',
'uploadImage', 'blockQuote', '|',
'undo', 'redo'
],
shouldNotGroupWhenFull: true
}
# 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 Creating a simple plugin guide to learn how to build your own plugin, register its button and add it to the toolbar configuration.
# Block toolbar
The BlockToolbar feature provides an additional configurable toolbar on the left-hand side of the content area, useful when the main toolbar is not accessible (e.g. in certain balloon block editor scenarios).
