Hi Shravya,
To properly add your webpage_schema_type field to the SEO dialog, you'll need to modify both the Python model and the OWL component. Here's a complete solution:

1. First, ensure your model extension is correct (Python)

python

from odoo import models, fields

class WebsitePage(models.Model):
    _inherit = 'website.page'

    webpage_schema_type = fields.Selection(
        selection=[
            ('WebPage', 'WebPage'),
            ('AboutPage', 'About Page'),
            ('CheckoutPage', 'Checkout Page'),
            ('CollectionPage', 'Collection Page'),
            ('ContactPage', 'Contact Page'),
            ('FAQPage', 'FAQ Page'),
            ('ProfilePage', 'Profile Page'),
            ('SearchResultsPage', 'Search Results Page'),
        ],
        string="Schema.org Type",
        default="WebPage",
        help="Select Schema Markup type for structured data"
    )

2. Create a JS module to extend the SEO dialog

Create a new file in your module: static/src/js/seo_dialog_extension.js

javascript

/** @odoo-module **/

import { patch } from "@web/core/utils/patch";
import { SeoDialog } from "@website/js/components/dialog/seo";

patch(SeoDialog.prototype, {
    setup() {
        super.setup();
        this.schemaOptions = [
            { value: 'WebPage', label: 'WebPage' },
            { value: 'AboutPage', label: 'About Page' },
            { value: 'CheckoutPage', label: 'Checkout Page' },
            { value: 'CollectionPage', label: 'Collection Page' },
            { value: 'ContactPage', label: 'Contact Page' },
            { value: 'FAQPage', label: 'FAQ Page' },
            { value: 'ProfilePage', label: 'Profile Page' },
            { value: 'SearchResultsPage', label: 'Search Results Page' },
        ];
    },

    /**
     * @override
     */
    async willStart() {
        const res = await super.willStart(...arguments);
        this.state.webpage_schema_type = this.initialValues.webpage_schema_type || 'WebPage';
        return res;
    },

    /**
     * @override
     */
    _prepareSEOPayload() {
        const payload = super._prepareSEOPayload();
        payload.webpage_schema_type = this.state.webpage_schema_type;
        return payload;
    },
});

// Add the field to the template
SeoDialog.template = 'your_module.SeoDialogExtended';

3. Create an XML template extension

Add to your module's views: views/seo_dialog_extension.xml

xml

<template id="SeoDialogExtended" inherit_id="website.SeoDialog" name="SEO Dialog Extended">
    <xpath expr="//div[hasclass('o_seo_configuration')]" position="before">
        <div class="form-group">
            <label class="col-form-label">Schema.org Type</label>
            <select t-att-name="'webpage_schema_type'" class="form-select" t-att-value="state.webpage_schema_type">
                <t t-foreach="schemaOptions" t-as="option">
                    <option t-att-value="option.value" t-esc="option.label"/>
                </t>
            </select>
        </div>
    </xpath>
</template>

4. Update your module assets

Add to your module's manifest (__manifest__.py):

python

'assets': {
    'web.assets_frontend': [
        'your_module/static/src/js/seo_dialog_extension.js',
    ],
    'web.assets_qweb': [
        'your_module/views/seo_dialog_extension.xml',
    ],
},

5. Update the website controller (optional)

To make the field available in the editor:

python

class Website(models.Model):
    _inherit = 'website'

    def _prepare_website_page_values(self, page):
        values = super()._prepare_website_page_values(page)
        values['webpage_schema_type'] = page.webpage_schema_type
        return values

Key Points:

1. The patch modifies the original SeoDialog component to:
   • Add your schema options
   • Include the field in the state
   • Ensure it's saved with the SEO data
2. The template inheritance adds your field to the existing dialog layout
3. The manifest updates ensure your JS and XML are properly loaded
4. This approach doesn't replace the whole component, just extends it cleanly

After implementing this, your field should appear in the SEO dialog and be properly saved with the page data. The value will be available on the website.page model for use in your templates or other business logic.
