# Forms

`FormsHandler` integrates Naja with `nette-forms` script if it is loaded. It initializes forms added to the page via
snippets and prevents their submission if they fail to validate.


## Custom nette-forms

By default, the nette-forms object is expected to reside in the global namespace: `window.Nette`. If you use ES modules
and import nette-forms into a different variable, you should configure the correct reference manually:

```js
import netteForms from 'nette-forms';
naja.formsHandler.netteForms = netteForms;
```

?> The nette-forms reference is configurable in this way since version 1.5.0.
