items[]

Configures toolbar items. These items allow users to format text and execute commands.

Type:

Array<Object | String>

Accepted Values: 'background' | 'bold' | 'color' | 'font' | 'italic' | 'link' | 'image' | 'size' | 'strike' | 'subscript' | 'superscript' | 'underline' | 'blockquote' | 'header' | 'increaseIndent' | 'decreaseIndent' | 'orderedList' | 'bulletList' | 'alignLeft' | 'alignCenter' | 'alignRight' | 'alignJustify' | 'codeBlock' | 'variable' | 'separator' | 'undo' | 'redo' | 'clear' | 'insertTable' | 'insertRowAbove' | 'insertRowBelow' | 'insertColumnLeft' | 'insertColumnRight' | 'deleteColumn' | 'deleteRow' | 'deleteTable'

The toolbar provides predefined items and supports custom items. To add a predefined item to the toolbar, include it in the items array:

JavaScript
$(function(){
    $("#htmlEditorContainer").dxHtmlEditor({
        toolbar: {
            items: [ "bold", "italic", "alignCenter", "undo", "redo" ]
        }

Most of the predefined items are buttons. To customize a button, assign its name to the name property and specify the button options in the options object:

jQuery
JavaScript
$(function(){
    $("#htmlEditorContainer").dxHtmlEditor({
        toolbar: {
            items: [ // ...
            { 
                name: "clear",

To use another UI component instead of a button, specify the widget property and configure the UI component in the options object. In this case, you should also implement all the logic.

The toolbar provides a short syntax for implementing a custom drop-down menu with multiple choices. Refer to the name description for more information.

View Demo

acceptedValues

Specifies values for a format with multiple choices. Should be used with the name.

Type:

Array<String | Number | Boolean>

Formats with multiple choices are represented by SelectBox UI components whose properties you can specify in the options object.

View Demo

component

An alias for the template property specified in React. Accepts a custom component. Refer to Using a Custom Component for more information.

cssClass

Specifies a CSS class to be applied to the item.

Type:

String

Default Value: undefined

disabled

Specifies whether the UI component item responds to user interaction.

Type:

Boolean

Default Value: false

formatName Deprecated

Use the name property instead.

Specifies the predefined item that this object customizes or a format with multiple choices.

Type:

String

Accepted Values: 'background' | 'bold' | 'color' | 'font' | 'italic' | 'link' | 'image' | 'size' | 'strike' | 'subscript' | 'superscript' | 'underline' | 'blockquote' | 'header' | 'increaseIndent' | 'decreaseIndent' | 'orderedList' | 'bulletList' | 'alignLeft' | 'alignCenter' | 'alignRight' | 'alignJustify' | 'codeBlock' | 'variable' | 'separator' | 'undo' | 'redo' | 'clear' | 'insertTable' | 'insertRowAbove' | 'insertRowBelow' | 'insertColumnLeft' | 'insertColumnRight' | 'deleteColumn' | 'deleteRow' | 'deleteTable'

formatValues Deprecated

Use the acceptedValues property instead.

Specifies values for a format with multiple choices.

Type:

Array<String | Number | Boolean>

html

Specifies the HTML markup to be inserted into the item element.

Type:

String

The HtmlEditor component evaluates the html property's value. This evaluation, however, makes the HtmlEditor potentially vulnerable to XSS attacks. To guard against these attacks, encode the HTML markup before you assign it to the html property. Refer to the following help topic for more information: Potentially Vulnerable API - html.

You can use the text property as a safe alternative.

locateInMenu

Specifies when to display an item in the toolbar's overflow menu.

Type:

String

Default Value: 'never'
Accepted Values: 'always' | 'auto' | 'never'

location

Specifies a location for the item on the toolbar.

Type:

String

Default Value: 'before'
Accepted Values: 'after' | 'before' | 'center'

Whatever template you use for UI component items (default or a custom) will be located according to the value specified for the location field in the item data source object.

menuItemComponent

An alias for the menuItemTemplate property specified in React. Accepts a custom component. Refer to Using a Custom Component for more information.

menuItemRender

An alias for the menuItemTemplate property specified in React. Accepts a rendering function. Refer to Using a Rendering Function for more information.

menuItemTemplate

Specifies a template that should be used to render a menu item.

Type:

template

Template Data: undefined

The following types of the specified value are available.

  • Assign a string containing the name of the required template.
  • Assign a jQuery object of the template's container.
  • Assign a DOM Node of the template's container.
  • Assign a function that returns the jQuery object or a DOM Node of the template's container.

name

Specifies the predefined item that this object customizes or a format with multiple choices.

Type:

String

Accepted Values: 'background' | 'bold' | 'color' | 'font' | 'italic' | 'link' | 'image' | 'size' | 'strike' | 'subscript' | 'superscript' | 'underline' | 'blockquote' | 'header' | 'increaseIndent' | 'decreaseIndent' | 'orderedList' | 'bulletList' | 'alignLeft' | 'alignCenter' | 'alignRight' | 'alignJustify' | 'codeBlock' | 'variable' | 'separator' | 'undo' | 'redo' | 'clear' | 'insertTable' | 'insertRowAbove' | 'insertRowBelow' | 'insertColumnLeft' | 'insertColumnRight' | 'deleteColumn' | 'deleteRow' | 'deleteTable'

To customize a predefined item, assign its name to this property and specify the other item properties.

This property also accepts names of formats with multiple choices. In addition to the format name, specify acceptedValues. On the toolbar, such formats are represented by SelectBox UI components whose properties you can specify in the options object.

In the following code, the header and size formats are configured as described in the previous paragraph:

options

Configures the DevExtreme UI component used as a toolbar item.

Type: any

options should contain the properties of the DevExtreme UI component specified in the widget property. Because of this dependency, options cannot be typed and are not implemented as nested configuration components in Angular, Vue, and React. In these frameworks, specify options with an object. We recommend that you declare the object outside the configuration component in Vue and React to prevent possible issues caused by unnecessary re-rendering.

In the following example, the CheckBox UI component is added as a custom toolbar item. It has a label and a custom valueChanged event handler. The toolbar item's locateInMenu property is set to "never" to specify that the toolbar item should never be hidden in the overflow menu.
