Upon choosing the Bulk-embed option on Vidjet, you'll need to embed once the embed code (iframe) in your master product page.
Most website editors propose a product-page template, sometimes called "defaut" or "master" page. This page enables you to structure the same layout for thousands of pages, and inject dynamic content into them.
Here is how to proceed on Shopify and Elementor for WordPress.
On Shopify
On your Shopify admin, you will have to:
Go to "Online Store", inside the "Sales channels" section
Select "Themes"
Click "Customize"
Select "Default product"
Add a section with the Vidjet embed code
On Elementor
On the Elementor WordPress plugin, you will have to:
Go to the āTemplatesā page
Select the āTheme Builderā tab.
Then, select the template associated to your product pages
Open your Elementor page editor
Add an HTML block to your master product page with the Vidjet embed code
š Remember: the logic is the same on other website editors. The key part is finding where to edit the page template (also called master page, or default page).
