Toolbar in EJ2 TypeScript Rich text editor control

14 Oct 202424 minutes to read

The Rich Text Editor toolbar contains a collection of tools such as bold, italic, and text alignment buttons that are used to format the content. However, in most integrations, you can customize the toolbar configurations easily to suit your needs.

To create Rich Text Editor with Markdown editing feature, inject the Toolbar module to the Rich Text Editor using the RichTextEditor.Inject(Toolbar) method.

The Rich Text Editor allows you to configure different types of toolbar using toolbarSettings.type property. The types of toolbar are:

Expand
MultiRow

The default mode of toolbarSettings.type it will hide the overflowing items in the next row. By clicking the expand arrow, view the overflowing toolbar items.

import { RichTextEditor, Toolbar, HtmlEditor } from '@syncfusion/ej2-richtexteditor';

let defaultRTE: RichTextEditor = new RichTextEditor({

    value: ` <p>The Rich Text Editor component is WYSIWYG ("what you see is what you get") editor that provides the best user experience to create and update the content.Users can format their content using standard toolbar commands.</p>

By default, tools will be arranged in following order.

items: [‘Bold’, ‘Italic’, ‘Underline’, ‘ ’, ‘Formats’, ‘Alignments’, ‘Blockquote’, ‘OrderedList’, ‘UnorderedList’, ‘ ’, ‘CreateLink’, ‘Image’, ‘ ’, ‘SourceCode’, ‘Undo’, ‘Redo’]

The tools order can be customized as our application requirement. If you are not specifying any tools order, the editor will create the toolbar with default items.

Custom tool

The Rich Text Editor allows you to configure your own commands to its toolbar using the toolbarSettings property. The command can be plain text, icon, or HTML template. The order and the group can also be defined where the command should be included. Bind the action to the command by getting its instance.

This sample shows how to add your own commands to the toolbar of the Rich Text Editor. The “Ω” command is added to insert special characters in the editor. By clicking the “Ω” command, it will show the special characters list, and then choose the character to be inserted in the editor.

The following code snippet illustrates custom tool with tooltip text which will be included in items field of the toolbarSettings property.

In the following sample, once Rich Text Editor control is created, the concern event will be created the Dialog component can be rendered and target as RTE content.

{
    tooltipText: 'Insert Symbol',
    undo: true,
    click: function() {
    },
    template: '<button class="e-tbar-btn e-btn" tabindex="-1" id="custom_tbar" style="width:100%"><div class="e-tbar-btn-text" style="font-weight: 500;"> &#937;</div></button>'
}

Click the Ω command to show the special characters list, and then choose the character to be inserted in the editor.

The focus will be lost while rendering the required component for the custom toolbar, causing it to render outside the Rich Text Editor and triggering a blur event. During that time, proper functionality will not be achievable. Therefore, it is recommended to set the cssClass property or class as e-rte-elements in the dependency component.

Quick commands are opened as context-menu on clicking the corresponding element. The commands must be passed as string collection to image, text, and link attributes of the quickToolbarSettings property.

Target Element	Default Quick Toolbar items
image	‘Replace’, ‘Align’, ‘Caption’, ‘Remove’, ‘InsertLink’, ‘Display’, ‘AltText’,’Dimension’.
link	‘Open’, ‘Edit’, ‘UnLink’.
text	null (Any toolbar items in the Rich Text Editor can be configured here).
table	‘TableHeader’, ‘TableRows’, ‘TableColumns’, ‘BackgroundColor’, ‘TableRemove’, ‘Alignments’, ‘TableCellVerticalAlign’, ‘Styles’.

Custom tool can be added to the corresponding quick toolbar, using quickToolbarSettings property.

The following sample demonstrates the option to insert the image to the Rich Text Editor content as well as option to rotate the image through the quick toolbar. The image rotation functionalities have been achieved through the toolbarClick event.

index.ts
index.html
import { RichTextEditor, Toolbar, Link, Image, HtmlEditor, QuickToolbar } from '@syncfusion/ej2-richtexteditor';
    RichTextEditor.Inject(Toolbar, Link, Image, HtmlEditor, QuickToolbar);
    let defaultRTE: RichTextEditor = new RichTextEditor({
      height: 340,
      quickToolbarSettings: {
         image: [
            'Replace', 'Align', 'Caption', 'Remove', 'InsertLink', 'OpenImageLink', '-',
            'EditImageLink', 'RemoveImageLink', 'Display', 'AltText', 'Dimension'
         ]
       },
      toolbarSettings: {
         items: ['Bold', 'Italic', 'Underline', 'StrikeThrough',
            'FontName', 'FontSize', 'FontColor', 'BackgroundColor',
            'LowerCase', 'UpperCase', '|',
            'Formats', 'Alignments', 'OrderedList', 'UnorderedList',
            'Outdent', 'Indent', '|',
            'CreateLink', 'Image', '|', 'ClearFormat', 'Print',
            'SourceCode', 'FullScreen', '|', 'Undo', 'Redo']
       }

    });
  defaultRTE.appendTo('#defaultRTE');
