React HtmlEditor - toolbar.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'

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

jQuery
JavaScript
$(function(){
    $("#htmlEditorContainer").dxHtmlEditor({
        toolbar: {
            items: [ "bold", "italic", "alignCenter", "undo", "redo" ]
        }
    })
})
Angular
HTML
TypeScript
<dx-html-editor>
    <dxo-toolbar [items]="[ 'bold', 'italic', 'alignCenter', 'undo', 'redo' ]"></dxo-toolbar>
</dx-html-editor>
import { DxHtmlEditorModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxHtmlEditorModule
    ],
    // ...
})
ASP.NET MVC Controls
Razor C#
@(Html.DevExtreme().HtmlEditor()
    .Toolbar(t => t
        .Items(i => {
            i.Add().FormatName("bold");
            i.Add().FormatName("italic");
            i.Add().FormatName("alignCenter");
            i.Add().FormatName("undo");
            i.Add().FormatName("redo");
        })
    )
)

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

jQuery
JavaScript
$(function(){
    $("#htmlEditorContainer").dxHtmlEditor({
        toolbar: {
            items: [ // ...
            { 
                formatName: "clear", 
                options: { icon: "clear", type: "danger" }
            }]
        }
    })
})
Angular
TypeScript
HTML
import { DxHtmlEditorModule } from "devextreme-angular";
// ...
export class AppComponent {
    items: any = [ // ...
    { 
        formatName: "clear", 
        options: { icon: "clear", type: "danger" }
    }];
}
@NgModule({
    imports: [
        // ...
        DxHtmlEditorModule
    ],
    // ...
})
<dx-html-editor>
    <dxo-toolbar [items]="items"></dxo-toolbar>
</dx-html-editor>
ASP.NET MVC Controls
Razor C#
@(Html.DevExtreme().HtmlEditor()
    .Toolbar(t => t
        .Items(i => { 
            i.Add().FormatName("clear")
                .Widget(w => w.Button()
                    .Icon("clear")
                    .Type(ButtonType.Danger)
                );
        })
    )
)

To use another widget instead of a button, specify the widget option and configure the widget 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 formatName description for more information.

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 widget item responds to user interaction.

Type:

Boolean

Default Value: false

formatName

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'

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

This option also accepts names of formats with multiple choices. In addition to the format name, specify formatValues. On the toolbar, such formats are represented by SelectBox widgets whose options you can specify in the options object.

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

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

        }
    }, {
        formatName: "size",
        formatValues: ["11px", "14px", "16px"]
    }];
}

    ],
    // ...

options

Configures the DevExtreme widget used as a toolbar item.

Type:

Object

options should contain the options of the DevExtreme widget specified in the widget option. 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.

View Demo

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

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