Forms are designed using components arranged in simple or complex structures depending on requirements. In most cases, each form component is directly associated with a field or attribute of the data source. The **Label** and **Attachments** components are exceptions, as they are not directly linked to a data source field or attribute. The form design interface allows you to define both the **content** and the **layout** of components. The illustration below presents the main sections of the form design interface.
