Angular HtmlEditor - Predefined Items

Toolbar items allow users to format the HTML Editor'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:

HTML
TypeScript
  • <dx-html-editor>
  • <dxo-toolbar>
  • <dxi-item name="bold"/>
  • <dxi-item name="italic"/>
  • <dxi-item name="alignRight"/>
  • <dxi-item name="alignLeft"/>
  • </dxo-toolbar>
  • </dx-html-editor>
  • import { DxHtmlEditorModule } from "devextreme-angular";
  • // ...
  • export class AppComponent {
  • // ...
  • }
  • @NgModule({
  • imports: [
  • // ...
  • DxHtmlEditorModule
  • ],
  • // ...
  • })

To add a select box, specify the name and acceptedValues:

HTML
TypeScript
  • <dx-html-editor>
  • <dxo-toolbar>
  • <dxi-item
  • [acceptedValues]="headerAcceptedValues"
  • name="header"
  • />
  • <dxi-item
  • [acceptedValues]="alignAcceptedValues"
  • name="align"
  • />
  • </dxo-toolbar>
  • </dx-html-editor>
  • import { DxHtmlEditorModule } from "devextreme-angular";
  • // ...
  • export class AppComponent {
  • headerAcceptedValues = [1, 2, 3, false];
  • alignAcceptedValues = ["left", "right", "center"];
  • }
  • @NgModule({
  • imports: [
  • // ...
  • DxHtmlEditorModule
  • ],
  • // ...
  • })

Customize Predefined Items

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

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" };
  • }
  • @NgModule({
  • imports: [
  • // ...
  • DxHtmlEditorModule
  • ],
  • // ...
  • })

To customize a select box, specify select box properties in the options object in addition to the name and acceptedValues properties:

HTML
TypeScript
  • <dx-html-editor>
  • <dxo-toolbar>
  • <dxi-item
  • [options]="sizeFormatOptions"
  • [acceptedValues]="sizeAcceptedValues"
  • name="size"
  • />
  • </dxo-toolbar>
  • </dx-html-editor>
  • import { DxHtmlEditorModule } from "devextreme-angular";
  • // ...
  • export class AppComponent {
  • sizeAcceptedValues = ["11px", "14px", "16px"];
  • sizeFormatOptions = { width: 150 };
  • }
  • @NgModule({
  • imports: [
  • // ...
  • DxHtmlEditorModule
  • ],
  • // ...
  • })
