Section Layout Component
SAIL Design System guidance available for Section Layout

The arrangement of the information on your interface will be a determining factor in the usability and usefulness of your design. Learn how to use sections to visually group the related parts of your interface.

Function

a!sectionLayout( label, contents, validations, validationGroup, isCollapsible, isInitiallyCollapsed, showWhen, divider, marginBelow, accessibilityText, labelIcon, iconAltText, labelSize, labelHeadingTag, labelColor, dividerColor, dividerWeight, marginAbove )

This layout requires Appian for Mobile Devices version 17.2 or later. Displays any arrangement of layouts and components beneath a section title on an interface.

Parameters

Name Keyword Types Description

Label

label

Text

Text to display as the section's title.

Contents

contents

Any Type

Components and layouts to display in the section body.

Validations

validations

List of Variant

Validation errors to display above the section.

Validation Group

validationGroup

Text

When present, the requiredness of the field is only evaluated when a button in the same validation group is pressed. The value for this parameter cannot contain spaces. For example, “validation group” is not a valid value. You need to add an underscore between words: “validation_group”. See the following recipes for more information:

Collapsible

isCollapsible

Boolean

Determines if an expand/collapse control appears in the section label. Default is false.

Initially Collapsed

isInitiallyCollapsed

Boolean

Determines if the section is collapsed when the interface first loads. Default is false.

Visibility

showWhen

Boolean

Determines whether the layout is displayed on the interface. When set to false, the layout is hidden and is not evaluated. Default: true.

Divider Line

divider

Text

Determines where a divider appears within the section. Valid values: "NONE" (default), "ABOVE", "BELOW".

Margin Below

marginBelow

Text

Determines how much space is added below the layout. Valid values: "NONE", "EVEN_LESS", "LESS", "STANDARD" (default), "MORE", "EVEN_MORE".

Accessibility Text

accessibilityText

Text

Additional text to be announced by screen readers. Used only for accessibility; produces no visible change.

Label Icon

labelIcon

Text

Icon to display next to the label. For a list of available icons, see the Styled Icon component.

Icon Alternative Text

iconAltText

Text

Equivalent alternate text for use by screen readers.

Label Size

labelSize

Text

Determines the label size. Valid values: "LARGE_PLUS", "LARGE", "MEDIUM_PLUS", "MEDIUM" (default), "SMALL", "EXTRA_SMALL".

Accessibility Heading Tag

labelHeadingTag

Text

Determines the heading tag associated with the label for use by screen readers; produces no visible change. Valid values: "H1", "H2", "H3", "H4", "H5", "H6". The default is dependent on the chosen label size. For more information on header tags, see our header accessibility guidance.

Label Color

labelColor

Text

Determines the label color. Valid values: Any valid hex color or "ACCENT" (default), "STANDARD", "POSITIVE", "NEGATIVE", "SECONDARY".

Divider Color

dividerColor

Text

Determines the divider line color. Valid values: Any valid hex color or "SECONDARY" (default), "STANDARD", "ACCENT".

Divider Weight

dividerWeight

Text

Determines the divider line thickness. Valid values: "THIN" (default), "MEDIUM", "THICK".

Margin Above

marginAbove

Text

Determines how much space is added above the layout. Valid values: "NONE" (default), "EVEN_LESS", "LESS", "STANDARD", "MORE", "EVEN_MORE".

Usage considerations

Validations

  • Sections that contain validation messages are not collapsible regardless of the collapsible parameter's value. For example, if a validation is triggered when the form loads, then that section is expanded even if you have specified true for the isInitiallyCollapsed parameter.
  • If you have nested section layouts, any validations on an inner section will also appear in the outer section.

Section headers

  • The labelHeadingTag parameter allows you to add a descriptive tag to a section heading so that screen readers can more easily convey page structure to the user. For more information and examples, see our design guidance on Accessible Headers.
