# Sign app item

> [HTML Version](app-signature.html)

This widget is used to sign app items using a qualified signature. It automatically  appears on the top panel of a document’s form as the **(sign-button.png) **button. To display the widget for the user, the [system administrator](360006871932.md#administrators) needs to:

- Set up the signing module. In addition to[ standard modules](electronic-signature.md), integration with any electronic signature provider is available.

- The user has the permission to sign the document.
