Page Designer Skill

This skill guides you through creating custom Page Designer page types and component types for Salesforce B2C Commerce.

Overview

Page Designer allows merchants to create and manage content pages through a visual editor. Developers create:

1. Page Types - Define page structures with regions
2. Component Types - Reusable content blocks with configurable attributes

File Structure

Page Designer files are in the cartridge's experience directory:

/my-cartridge
    /cartridge
        /experience
            /pages
                homepage.json           # Page type meta definition
                homepage.js             # Page type script
            /components
                banner.json             # Component type meta definition
                banner.js               # Component type script
        /templates
            /default
                /experience
                    /pages
                        homepage.isml   # Page template
                    /components
                        banner.isml     # Component template

Naming: The .json and .js files must have matching names. Use only alphanumeric or underscore in file names and in any subdirectory names under experience/pages or experience/components.

Component types in subfolders: You can put component meta and script in a subdirectory (e.g. experience/components/assets/). The component type ID is then the path with dots: assets.hero_image_block. The template path under templates/default/ must mirror that path (e.g. templates/default/experience/components/assets/hero_image_block.isml), and the script must call Template('experience/components/assets/hero_image_block') so the path matches. Stored ID is component.{component_type_id}; total length must not exceed 256 characters.

Page Types

Meta Definition (pages/homepage.json)

{
    "name": "Home Page",
    "description": "Landing page with hero and content regions",
    "region_definitions": [
        {
            "id": "hero",
            "name": "Hero Section",
            "max_components": 1
        },
        {
            "id": "content",
            "name": "Main Content"
        },
        {
            "id": "footer",
            "name": "Footer Section",
            "component_type_exclusions": [
                { "type_id": "video" }
            ]
        }
    ]
}

Page Script (pages/homepage.js)

'use strict';

var Template = require('dw/util/Template');
var HashMap = require('dw/util/HashMap');

module.exports.render = function (context) {
    var model = new HashMap();
    var page = context.page;

    model.put('page', page);

    return new Template('experience/pages/homepage').render(model).text;
};

Page Template (templates/experience/pages/homepage.isml)

<isdecorate template="common/layout/page">
    <isscript>
        var PageRenderHelper = require('*/cartridge/experience/utilities/PageRenderHelper');
    </isscript>

    <div class="homepage">
        <div class="hero-region">
            <isprint value="${PageRenderHelper.renderRegion(pdict.page.getRegion('hero'))}" encoding="off"/>
        </div>

        <div class="content-region">
            <isprint value="${PageRenderHelper.renderRegion(pdict.page.getRegion('content'))}" encoding="off"/>
        </div>

        <div class="footer-region">
            <isprint value="${PageRenderHelper.renderRegion(pdict.page.getRegion('footer'))}" encoding="off"/>
        </div>
    </div>
</isdecorate>

Component Types

Meta Definition (components/banner.json)

{
    "name": "Banner",
    "description": "Promotional banner with image and CTA",
    "group": "content",
    "region_definitions": [],
    "attribute_definition_groups": [
        {
            "id": "image",
            "name": "Image Settings",
            "attribute_definitions": [
                {
                    "id": "image",
                    "name": "Banner Image",
                    "type": "image",
                    "required": true
                },
                {
                    "id": "alt",
                    "name": "Alt Text",
                    "type": "string",
                    "required": true
                }
            ]
        },
        {
            "id": "content",
            "name": "Content",
            "attribute_definitions": [
                {
                    "id": "headline",
                    "name": "Headline",
                    "type": "string",
                    "required": true
                },
                {
                    "id": "body",
                    "name": "Body Text",
                    "type": "markup"
                },
                {
                    "id": "ctaUrl",
                    "name": "CTA Link",
                    "type": "url"
                },
                {
                    "id": "ctaText",
                    "name": "CTA Button Text",
                    "type": "string"
                }
            ]
        },
        {
            "id": "layout",
            "name": "Layout Options",
            "attribute_definitions": [
                {
                    "id": "alignment",
                    "name": "Text Alignment",
                    "type": "enum",
                    "values": ["left", "center", "right"],
                    "default_value": "center"
                },
                {
                    "id": "fullWidth",
                    "name": "Full Width",
                    "type": "boolean",
                    "default_value": false
                }
            ]
        }
    ]
}

Component meta: Always include region_definitions. Use [] when the component has no nested regions (no slots for other components).

Component Script (components/banner.js)

'use strict';

var Template = require('dw/util/Template');
var HashMap = require('dw/util/HashMap');
var URLUtils = require('dw/web/URLUtils');

module.exports.render = function (context) {
    var model = new HashMap();
    var content = context.content;

    // Access merchant-configured attributes
    model.put('image', content.image);        // Image object
    model.put('alt', content.alt);            // String
    model.put('headline', content.headline);  // String
    model.put('body', content.body);          // Markup string
    model.put('ctaUrl', content.ctaUrl);      // URL object
    model.put('ctaText', content.ctaText);    // String
    model.put('alignment', content.alignment || 'center');
    model.put('fullWidth', content.fullWidth);

    return new Template('experience/components/banner').render(model).text;
};

Template path: The path passed to Template(...) must match the template path under templates/default/. If the component lives in a subfolder (e.g. experience/components/assets/hero_image_block), use Template('experience/components/assets/hero_image_block') and place the ISML at templates/default/experience/components/assets/hero_image_block.isml.

Handling colors (string or color picker object): If an attribute can be a hex string or a color picker object {color: "#hex"}, use a small helper so the script works with both:

function getColor(colorAttr) {
    if (!colorAttr) return '';
    if (typeof colorAttr === 'string' && colorAttr.trim()) return colorAttr.trim();
    if (colorAttr.color) return colorAttr.color;
    return '';
}

Component Template (templates/experience/components/banner.isml)

<div class="banner ${pdict.fullWidth ? 'banner--full-width' : ''}"
     style="text-align: ${pdict.alignment}">
    <isif condition="${pdict.image}">
        <img src="${pdict.image.file.absURL}"
             alt="${pdict.alt}"
             class="banner__image"/>
    </isif>

    <div class="banner__content">
        <h2 class="banner__headline">${pdict.headline}</h2>

        <isif condition="${pdict.body}">
            <div class="banner__body">
                <isprint value="${pdict.body}" encoding="off"/>
            </div>
        </isif>

        <isif condition="${pdict.ctaUrl && pdict.ctaText}">
            <a href="${pdict.ctaUrl}" class="banner__cta btn btn-primary">
                ${pdict.ctaText}
            </a>
        </isif>
    </div>
</div>

Attribute Types

Enum — critical for component visibility: Use a string array for values: "values": ["left", "center", "right"]. Do not use objects like {"value": "x", "display_value": "X"}; that format can cause the component type to be rejected and not appear in the Page Designer component list.

Custom and colors: type: "custom" with e.g. editor_definition.type: "styling.colorPicker" requires a cartridge that provides that editor on the Business Manager site cartridge path. If the component does not show up in the editor, use type: "string" for color attributes (merchant types a hex). In the script, support both: accept a string or an object like {color: "#hex"} (e.g. a small getColor(attr) helper that returns the string).

default_value: Used for storefront rendering only; it is not shown as preselected in the Page Designer visual editor.

Region Definitions

{
    "region_definitions": [
        {
            "id": "main",
            "name": "Main Content",
            "max_components": 10,
            "component_type_exclusions": [
                { "type_id": "heavy-component" }
            ],
            "component_type_inclusions": [
                { "type_id": "text-block" },
                { "type_id": "image-block" }
            ]
        }
    ]
}

Rendering Pages

In Controllers

var PageMgr = require('dw/experience/PageMgr');

server.get('Show', function (req, res, next) {
    var page = PageMgr.getPage(req.querystring.cid);

    if (page && page.isVisible()) {
        res.page(page.ID);
    } else {
        res.setStatusCode(404);
        res.render('error/notfound');
    }
    next();
});

In ISML

<isscript>
    var PageMgr = require('dw/experience/PageMgr');
    var page = PageMgr.getPage('homepage-id');
</isscript>

<isif condition="${page && page.isVisible()}">
    <isprint value="${PageMgr.renderPage(page.ID)}" encoding="off"/>
</isif>

Component Groups

Organize components in the editor sidebar:

{
    "name": "Product Card",
    "group": "products"
}

Common groups: content, products, navigation, layout, media

If the component does not appear in Page Designer

1. Enums: Ensure all enum attributes use "values": ["a", "b"] (string array), not objects with value/display_value.
2. Custom editors: Replace type: "custom" (e.g. color picker) with type: "string" for the problematic attributes and redeploy; if the component then appears, the issue is likely the custom editor or BM cartridge path.
3. Naming: File and subdirectory names only alphanumeric or underscore.
4. region_definitions: Component meta must include region_definitions (use [] if no nested regions).
5. Template path: Script Template('...') path must match the template path under templates/default/ (including subfolders like experience/components/assets/...).
6. Logs: In Business Manager, Administration > Site Development > Development Setup, check error logs when opening Page Designer for script or meta errors related to your component type ID.
7. Code version: Deploy the cartridge to the correct code version; in non-production, meta can be cached for a few seconds—try a code version switch or short wait.

Best Practices

1. Use dw.util.Template for rendering (NOT dw.template.ISML)
2. Keep components self-contained - avoid cross-component dependencies
3. Provide default values for optional attributes (they apply to rendering; not shown as preselected in the editor)
4. Group related attributes in attribute_definition_groups
5. Use meaningful IDs - they're used programmatically
6. Don't change type IDs or attribute types after merchants create content (creates inconsistency with stored data); add a new component type and deprecate the old one if needed
7. Prefer string arrays for enums and string for colors unless you control the BM cartridge path and custom editors
