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.
For clarity, all demos in this guide present a limited set of features. Visit the feature-rich editor example to see more in action.
# Basic toolbar configuration
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 plugins. Check removing features for more information.
In the builds that contain toolbars, an optimal default toolbar set is defined for it. You may need a different toolbar arrangement, though, and you can achieve this through configuration.
Each editor may have a different toolbar configuration scheme, so check its documentation. In any case, the following example may give you a general idea:
ClassicEditor
.create( document.querySelector( '#editor' ), {
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 ineditor.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 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 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 totrue
, 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.
# Block toolbar
The BlockToolbar feature provides an additional configurable toolbar on the left-hand side of the content area. It is useful when the main toolbar is not accessible (for example, in certain balloon block editor scenarios).
# Contribute
The source code of the feature is available on GitHub at https://github.com/ckeditor/ckeditor5/tree/master/packages/ckeditor5-ui.
