The GPSR widget shows each product's manufacturer, EU responsible person and document links on its product page. It needs to be on every product template your products use.
Go to GPSR › Widgets and click Add widget. Your theme editor opens on the next product template still missing it.
Place it under the product description, then click Save.
Come back to the app and repeat until it shows Added to 12 of 12 templates (your own numbers).
The widget needs an Online Store 2.0 theme. To move it later, click Edit in theme.
Everything is set in GPSR › Widgets, and applies to every template:
Layout: Stacked list, Table, Information cards or Collapsible sections.
Text and translations: the heading and the field labels, such as "Manufacturer", in your primary language and each language your store publishes.
What the widget shows: turn the manufacturer, EU responsible person, conformity declaration or manual on or off.
When to hide it: outside EU markets, and when a product has no GPSR information to show. If you don't hide it, empty products show your "No information" message.
Style: your own font sizes for the heading, labels and values (off uses your theme's), bold labels, and the space above and below.
