How to add a custom Toolbar

This topic shows you how to implement an inline toolbar for your content type. You can see an example of a toolbar in Page Builder’s Heading content type, as shown here:

Page Builder toolbar

Toolbars provide end-users with a quick way to change common properties of your content type (such as text alignment and heading types) without needing to open the full editor. The toolbar does not replace the need for form fields in the editor; it simply extends those fields.

How the Toolbar works

The diagram below shows the basic steps for adding a toolbar to your content type. It also shows how the various parts connect and work together.

Toolbar how it works

Step 1: Add toolbar options

Toolbar options are the clickable items in a toolbar that represent the property values of a form field. For example, the Heading content type adds toolbar options for the text_align field from pagebuilder_base_form.xml. The Heading adds the values of the text_align field (left, center, and right) as items on the toolbar, represented with the images provided by the icon CSS classes as shown here:

    key: "text_align",
    type: "select",
    values: [
            value: "left",
            label: "Left",
            icon: "icon-pagebuilder-align-left",
            value: "center",
            label: "Center",
            icon: "icon-pagebuilder-align-center",
            value: "right",
            label: "Right",
            icon: "icon-pagebuilder-align-right",

The OptionInterface and ValueInterface define the structure of toolbar options. You can find these interfaces in magento2-page-builder/app/code/Magento/PageBuilder/view/adminhtml/web/ts/js/content-type-toolbar.types.ts. Descriptions of the elements follow:

Element Description
key The field name you are binding to. For example: <field name="quote_css"...>
type The formElement of the key field. For example: <field ... formElement="select">
values Array of field option values.
value Field option value, such as a CSS class (as shown in the code example).
label Field option label, such as a label for a select option (as shown in the code example)
icon CSS class name for the icon to display in the toolbar to represent the field’s option. If you don’t include a CSS class, the toolbar will display the label instead.

Step 2: Create Toolbar instance

To create an instance of the Page Builder toolbar in your preview.js component:

  • Import Page Builder’s Toolbar class ('Magento_PageBuilder/js/content-type-toolbar')
  • Call the toolbar constructor. The Toolbar constructor requires you to pass your Preview component and the array of toolbar options you created in step 1 (this.toolbar = new Toolbar(this, this.getToolbarOptions());). You can find Page Builder’s Toolbar class in magento2-page-builder/app/code/Magento/PageBuilder/view/adminhtml/web/ts/js/content-type-toolbar.ts.
], function (PreviewBase, Toolbar) {
    'use strict';

    function Preview(parent, config, stageId) {, parent, config, stageId);
        this.toolbar = new Toolbar(this, this.getToolbarOptions());

Step 3: Add toolbar markup

Within your preview.html template, use a div element (with CSS class and events) to wrap whichever element in your template you want the toolbar to act on. For example, the custom Quote content type wraps its <blockquote> element within a div with the toolbar’s CSS class and event binding, as shown here:

<div attr="data.main.attributes" ko-style="" class="pagebuilder-content-type" css="data.main.css" event="{ mouseover: onMouseOver, mouseout: onMouseOut }, mouseoverBubble: false">
    <render args="getOptions().template"/>
    <div class="pagebuilder-toolbar-container" 
         event="{ focusin: toolbar.onFocusIn, focusout: toolbar.onFocusOut }">
        <with args="toolbar">
            <render args="template"/>
        <blockquote class="quote-content" attr="data.quote.attributes" css="data.quote.css" ko-style="" data-bind="liveEdit: { field: 'quote_text', placeholder: $t('Enter Quote') }"></blockquote>
    <div class="quote-author" attr="" ko-style="" css="" data-bind="liveEdit: { field: 'quote_author', placeholder: $t('Enter Author') }"></div>
    <div class="quote-description" attr="data.author_title.attributes" ko-style="" css="data.author_title.css" data-bind="liveEdit: { field: 'quote_author_desc', placeholder: $t('Enter Description') }"></div>

Line 4: Use this CSS class to correctly format and control the screen placement of the toolbar when the wrapped HTML element receives focus.

Line 5: Set a tabindex of 0 to ensure that the div wrapper is part of the default focus order for tabbing.

Line 6: Use the the Toolbar’s onFocusIn and onFocusOut methods to handle the events for focusin and focusout.

Lines 7-9: Add the toolbar’s HTML template as returned from your toolbar instance of the Toolbar class.

get template(): string {
    return "Magento_PageBuilder/content-type-toolbar";

You can find this HTML template here: app/code/Magento/PageBuilder/view/adminhtml/web/template/content-type-toolbar.html.
