Module Applications
The module is ideal for e-commerce where individual products require special presentations, such as:
- Electronics shops – adding interactive product demos using JavaScript.
- Clothing shops – custom CSS for unique category photo galleries.
- Supplement shops – JSON-LD for rich snippets with reviews and ingredients.
- Marketplace platforms – optimising category pages for better navigation.
- B2B businesses – hiding prices or adding contact forms via JS.
Features – Back Office
Editing resources in forms
Adding CSS, JS, and JSON-LD individually for each product, category and CMS - directly in the panels, with preliminary validation and preview.
Security and validation
Preliminary code control for threats, with blocking of dangerous constructs. Resources stored exclusively on the server disk, avoiding database writes and reducing the risk of Stored (Persistent) XSS attacks.
Asset synchronisation
Automatic scanning and updating of asset flags, with status reports.
Cache management
Built-in tools for clearing cache for immediate changes.
Features – Front Office
Structured data in head
JSON-LD injected as script type="application/ld+json" for better SEO, enabling implementation of schemas for FAQ, reviews and other solutions.
JavaScript before body
Scripts loaded before closing body, ideal for interactions without blocking rendering.
Dynamic CSS loading
Styles loaded in the head section, enabling immediate changes to page appearance.
Note!
Before installation, make a backup of the database and shop files. The module saves resources on disk — ensure the assets directory has appropriate permissions. Do not upload unverified code to avoid security issues. In case of errors, use the synchronisation function.

FAQs
-
Are the modules compatible with my version of PrestaShop?
Each module in our store contains information about compatibility with specific PrestaShop versions. Please check this information carefully before purchasing. If you are not sure, contact us.
-
Which pages can have custom assets assigned?
The module lets you assign individual CSS, JavaScript and JSON-LD assets to products, categories and CMS pages. Editing takes place directly in the relevant Back Office forms, so code can be tailored to a specific page without affecting other shop areas.
-
Does the module validate JSON-LD?
Yes. JSON-LD undergoes preliminary validation while assets are being edited. This lets you prepare structured data for specific pages, including FAQ and review schemas, before it is embedded in the page head section.
-
Where are the added assets stored?
Added assets are stored on the server disk rather than in the database. According to the product description, this approach reduces the risk of persistent XSS, while the module also performs preliminary code checks and blocks unsafe constructs.
-
Where on the page are CSS, JavaScript and JSON-LD loaded?
CSS styles are loaded in the head section, while JSON-LD is added as an application/ld+json script. JavaScript files are placed before the closing body tag. This separation follows the module’s organisation of the different asset types.
-
How can I refresh data after changing assets?
The module includes cache-management tools so changes can be applied immediately. It also provides a synchronisation mechanism that scans assets, updates their flags and reports the status of detected files.
