Some actions performed on a form affect the elements it contains. For example, [hiding](#hide) a form also effectively hides all the elements in the form, although the values of the [hidden](#hidden) properties of the elements contained in the form do not change. A `Form` element is added automatically when you add the [`WixForms`](https://dev.wix.com/docs/velo/velo-only-apis/$w/form/introduction.md) element to the page. These 2 elements work together to provide the functionality available with the Wix Forms app. Because they work together, if you hide or collapse either the `WixForms` or the `Form` element, the other element is also hidden/collapsed.
