# Decide to render a partial or not dynamically in Astro

> Learn how to decide whether an Astro route returns an HTML partial or a full page, by toggling export const partial and wrapping the output in a Layout.

Using htmx I have the need to render an HTML partial from a page, so I use:

```javascript
---
export const partial = true
---
```

What if, however, I decide I want to render a full page instead, maybe depending on the HTTP method used to reach this page?

I can still wrap the resulting HTML in a `<Layout>` component that renders the DOCTYPE, head tag and all.

And this will render the full page.

Otherwise if you just output an HTML fragment without wrapping in a layout, it’s an HTML partial.
