# up.form.isSubmittable(form)

Returns whether the given form will be [submitted](https://unpoly.com/learn/submitting-forms.md) through Unpoly instead of making a full page load.

By default, Unpoly will submit forms if the element has one of the following attributes:

- [`[up-submit]`](https://unpoly.com/api/up-submit.md)
- [`[up-target]`](https://unpoly.com/api/up-follow.md#up-target)
- [`[up-layer]`](https://unpoly.com/api/up-follow.md#up-layer)
- [`[up-transition]`](https://unpoly.com/api/up-transition.md)

To consider other selectors to be submittable, see [`up.form.config.submitSelectors`](https://unpoly.com/api/up.form.config.md#config.submitSelectors).
