Layout capabilities of adaptive forms
Adobe Experience Manager (AEM) lets you create easy-to-use adaptive forms that offer dynamic experiences to end users. The form layout controls how items or components are displayed in an adaptive form.
Types of layouts
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:
To change the layout of an adaptive form, use the Authoring Mode in AEM.
A form author can associate a layout with each panel of an adaptive form, including the root panel.
The Panel layouts are available at /libs/fd/af/layouts/panel location.

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 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.

Toolbar layouts are available at /libs/fd/af/layouts/toolbar location. adaptive forms provide the following Toolbar Layouts, by default.
Default layout for toolbar
This layout is selected as the default layout when you add any action buttons in an adaptive form. Selecting this layout displays the same layout for both, desktop and mobile devices.
Also, you can add multiple toolbars containing action buttons configured with this layout. An action button is associated with a form control. You can configure the toolbars to be before or after a panel.

Select this layout to provide alternate layouts for desktop and mobile devices.
For the desktop layout, you can add Action buttons using some specific labels. Only one toolbar can be configured with this layout. If more than one toolbar are configured with this layout, there is an overlap for mobile devices and only one toolbar is visible.
