Dear  Epicerie,

No direct QWeb template editing — Studio allows field injection and form/page customization, but deep HTML/QWeb overrides are limited.

Complex layouts (accordion, tabs) may require a custom module, which is not possible on Odoo Online unless published via Odoo Apps.

Performance: With 1,800+ products, avoid storing FAQs as plain text fields. Use relational models so content is structured and reusable.

So best approach would be go with custom module creation workflow and that will not support on online version.

Thanks 

Hi Epicerie,

This is definitely achievable in Odoo v19. Here's the quick overview:

For a single product template that works across all 1,800+ products, use QWeb template inheritance through a custom module, avoid the drag-and-drop builder as it creates page-specific overrides that won't scale.

For dynamic data injection, leverage product attributes for specs, the eCommerce description fields for content, and custom fields (x_ fields) on product.template for anything extra. Reference them directly in your QWeb template.

For the accordion FAQ, create a One2many field on the product template with question/answer pairs, then loop through them in your template using t-foreach inside a Bootstrap accordion. Fully dynamic, zero hardcoding.

One important note, since you're on Odoo v19 Online, you're limited in how much frontend customisation you can do. Studio can handle the custom fields, but for the QWeb-level template changes you're describing, you'd likely need Odoo.sh or On-Premise.

If you'd like, we can hop on a quick call and I can guide you through the implementation in more detail. Just let me know what works for you.
