jQuery HtmlEditor - Predefined Items

Toolbar items allow users to format the HtmlEditor's content and perform actions on it.

Predefined toolbar items include:

  • Buttons that apply single-choice formats to the text.
  • Action buttons.
  • Select boxes that apply multiple-choice formats.
  • Separators that are not user-interactive and only divide other elements.

To add a button to the toolbar, add its name to the items array:

jQuery
JavaScript
$(function(){
    $("#htmlEditorContainer").dxHtmlEditor({
        toolbar: {
            items: [ "bold", "italic", "alignRight", "alignLeft" ]
        }
    })

Customize Predefined Items

To customize a button, assign its name to the name property and specify button properties in the options object:

jQuery
JavaScript
$(function(){
    $("#htmlEditorContainer").dxHtmlEditor({
        toolbar: {
            items: [{
                name: "clear", 
                options: { icon: "clear", type: "danger" }
            }, // ...
            ]
        }
    })
})
Angular
HTML
TypeScript
<dx-html-editor>
    <dxo-toolbar>
        <dxi-item
            [options]="clearFormatOptions"
            name="clear">
        </dxi-item>
    </dxo-toolbar>
</dx-html-editor>
import { DxHtmlEditorModule } from "devextreme-angular";
// ...
export class AppComponent {
    clearFormatOptions = { icon: "clear", type: "danger" };

                    <Item
                        options={clearFormatOptions}
                        name="clear"
                    />
