An adaptive form provides you with the following types of layouts:

Panel Layout

Controls how items or components inside a panel are displayed on a device.

Mobile Layout

Controls the navigation of a form on a mobile device. If the device width is 768 pixels or more, the layout is considered a mobile layout and optimized for a mobile device.

Toolbar Layout

Controls the placement of Action buttons in the toolbar or panel toolbar in a form.

All these panel layouts are defined in the following location:

/libs/fd/af/layouts.

Wizard - a multi-step form showing one step at a time

Use this panel layout to provide guided navigation inside a form. For example, use this layout when you want to capture mandatory information in a form while guiding users step by step.

Use the Panel adaptive form component to provide step-by-step navigation inside a panel. When you use this layout, a user moves to the next step only after the current step is complete

Layout for accordion design

Using this layout, you can place the Panel adaptive form component in a panel with accordion style navigation. Using this layout, you can also create repeatable panels. Repeatable panels enable you to dynamically add or remove panels as needed. You can define the minimum and the maximum number of times a panel repeats. Also, the title of the panel can be determined dynamically, based on the information provided in the panel items.

Summary expression can be used to show the values provided by the end user in the title of the minimized panel.

Mobile layouts

Mobile layouts allow for user-friendly navigation on the mobile devices with relatively smaller screens. Mobile layouts use either tabbed or wizard styles for form navigation. Applying a Mobile Layout provides a single layout for the entire form.

This layout controls navigation using a navigation bar and a navigation menu. The navigation bar shows < and > icon to indicate next and previous navigation steps in the form. 

The Mobile Layouts are available at /libs/fd/af/layouts/mobile/ location. The following mobile layouts are available in adaptive forms, by default.
