This tutorial explains how to add an HtmlEditor to a page and configure its core features. The following control demonstrates the result:
Refer to the following sections for details on each configuration step. You can also find the full code in the GitHub repository.
Create an HtmlEditor
jQuery
The HtmlEditor uses the DevExtreme Quill library. To create an HtmlEditor on your page, add DevExtreme to your application, reference the DevExtreme Quill script before the main DevExtreme script, and use the following code:
index.js
index.html
$(function () {
$("#html-editor").dxHtmlEditor({
// Configuration goes here
});
});
<html>
<head>
<!-- ... -->
<script type="text/javascript" src="https://code.jquery.com/jquery-3.5.1.min.js"></script>

<script src="index.js"></script>

<div id="html-editor">

</div>
</body>
</html>Angular
The HtmlEditor uses the DevExtreme Quill library. This library is installed automatically when you add DevExtreme to your application. To create an HtmlEditor on your page, use the following code:
app.component.html
app.component.ts
app.module.ts
<dx-html-editor>
<!-- Configuration goes here -->
</dx-html-editor>
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
}
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { DxHtmlEditorModule } from 'devextreme-angular';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
DxHtmlEditorModule
],
providers: [ ],
bootstrap: [AppComponent]
})
export class AppModule { }Vue
The HtmlEditor uses the DevExtreme Quill library. This library is installed automatically when you add DevExtreme to your application. To create an HtmlEditor on your page, use the following code:
App.vue
<template>
<DxHtmlEditor>
<!-- Configuration goes here -->
</DxHtmlEditor>
</template>
<script>
import 'devextreme/dist/css/dx.light.css';
import { DxHtmlEditor } from 'devextreme-vue/html-editor';
export default {
components: {
DxHtmlEditor
}
}
</script>React
The HtmlEditor uses the DevExtreme Quill library. This library is installed automatically when you add DevExtreme to your application. To create an HtmlEditor on your page, and use the following code:
App.js
import React from 'react';
import './App.css';
import 'devextreme/dist/css/dx.light.css';
import { HtmlEditor } from 'devextreme-react/html-editor';
const App = () => {
return (
<HtmlEditor>
{/* Configuration goes here */}
</HtmlEditor>
);
}
export default App;Set the Output Markup Language
The HtmlEditor can output markup in HTML or Markdown. Use the valueType property to define the language. If you use Markdown, add the turndown and showdown libraries to your project. In this tutorial, HTML is used as the output language.
The control stores the document markup in the value property. If you use this property to specify the document's initial content, the language should match valueType. You can also declare HTML content inside the HtmlEditor element. In this case, the language (HTML) and valueType can differ.
jQuery
index.js
index.html
index.css
$(function () {
$("#html-editor").dxHtmlEditor({
valueType: "html"
});
});

}Configure the Toolbar
The HtmlEditor's toolbar contains buttons and drop-down menus that allow users to edit and format content. To configure the toolbar, specify an array of items in the toolbar object. You can use predefined items or create custom items. You can specify a list of accepted values for certain predefined items, such as font size. To do so, use the name property to define the item and the acceptedValues property to assign an array of available values.
If toolbar items overflow the length of the toolbar, enable the multiline property to arrange the items in multiple lines.

index.js
$(function () {
$("#html-editor").dxHtmlEditor({
// ...

items: [
"undo",

export default App;Users can also modify tables with the context menu if you set the tableContextMenu.enabled property to true. Note that the context menu cannot be used to create new tables because the menu is only available within table boundaries. If you want users to create tables, add an "insertTable" item to the toolbar.

export default App;NOTE
The HtmlEditor tables are native HTML tables that use native features; therefore, the same limitations apply. For example, users cannot paste multiline text in separate cells.
The HtmlEditor tables do not support complex elements in cells, such as block elements, lists, nested tables, etc.
Resize Images
Users can resize images embedded within the content. To enable this functionality, set the mediaResizing.enabled property to true:
jQuery
index.js
$(function () {
$("#html-editor").dxHtmlEditor({
// ...
mediaResizing: {
enabled: true
}
});
});Angular
app.component.html
