# Enable the theme app embed

The app embed is the recommended Shopify installation. Enable it once and Selvette can load on product pages across an Online Store 2.0 theme.

## Enable Selvette store-wide

1. In Shopify admin, open **Online Store → Themes**.
2. On the live theme, select **Customize**.
3. Open **App embeds** in the theme editor.
4. Turn on **Try-On (store-wide)**.
5. Leave the publishable-key and URL override fields blank for the standard one-click setup.
6. Choose a button placement:
   * **Inline** — next to or below Add to cart; recommended.
   * **Floating pill** — fixed at the bottom right.
   * **Hidden** — use a trigger already built into your theme.
7. Select **Save**.

The embed loads only when Shopify supplies a product to the page. It does not add the widget to home, collection, or cart pages.

## If your theme does not support app embeds

Vintage themes do not provide the Online Store 2.0 app-embed area. Use the [inline app block](/shopify-app/add-inline-block.md) instead.

## If both installation methods are enabled

Selvette prevents a second widget from mounting. You should still keep one preferred method enabled so the theme is easier to maintain.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.selvette.com/shopify-app/enable-app-embed.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
