# Build one page for a whole collection

> Build one product template from a collection's products, then assign it to every active product in that collection.

Under **Made for**, pick **Collection**. We build one product template from that collection's products. Then you assign it to the whole collection with one click. This builds a product page template, not a collection page.

## Build it

1. In Shopify admin, open **Apps** → **Section Store** → **AI Pages**.
2. On the **Product page** card, click **Build product page**.
3. Pick **Full product page**, **Buy box only** or **Sections only**. Click **Continue**.
4. Under **Made for**, pick **Collection**. Click **Select collection** and pick one.
5. Set the style and options you want. The template name starts as **collection-** plus the collection's name.
6. Click the Generate button.
7. Review the page with **Open theme editor**.
8. Click **Assign to the collection’s products**. You see **Assigned to** and the number of products.

## Good to know

- Every active product in the collection switches to this template.
- With more than 100 active products, the product picker opens. Pick up to 100 at a time.
- Products you add to the collection later keep their own template. Assign them too.
- **Match your collection** takes colors from the collection's photos. It needs at least two photos.

## If it doesn't work

- **"has no products. Add products to it or pick another collection."** The collection is empty. Add products or pick another one.
- **Some products didn't switch.** Draft and archived products aren't assigned.
