Header Content Layout Component

SAIL Design System guidance available for Header Content Layout

Give users a warm welcome to your page with the header content layout. Learn how to design your pages with two distinct zones to draw attention to any text or images that identify the purpose of the page or site.

Function

a!headerContentLayout( header, contents, showWhen, backgroundColor, contentsPadding, isHeaderFixed )

Displays any arrangement of layouts and components beneath a billboard or card header that is flush with the edge of the page. Similar to a form layout, this is a top-level layout and cannot be nested within other layouts. The header layout is ideal for landing pages and reports.

To add a header content layout to your interface from design mode, drag out either a CARD HEADER or BILLBOARD HEADER from the interface palette.

Parameters

Name Keyword Types Description

Header

header

Any Type

Billboard, card, or list of billboards or cards to display at the top of the page. Configure using a!billboardLayout() or a!cardLayout().

Contents

contents

Any Type Array

Components and layouts to display in the body of the interface.

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.

Background color

backgroundColor

Text

Color to show behind the contents of the page. Valid values: Any valid hex color or "WHITE" (default), "TRANSPARENT", "CHARCOAL_SCHEME", "NAVY_SCHEME", "PLUM_SCHEME".

Contents Padding

contentsPadding

Text

Determines the space surrounding the contents. Valid values: "NONE", "EVEN_LESS", "LESS", "STANDARD" (default), "MORE", "EVEN_MORE".

Fix header when scrolling

isHeaderFixed

Boolean

Determines whether the header remains at the top of the page when scrolling. When using a pane layout for the contents, this parameter is ignored. Default: false.

Usage considerations

Billboard videos

The backgroundMedia parameter accepts both images and videos. If you want to use a video for your billboard media, there are a few constraints to consider:

  • The video cannot be a document stored within your application like an image can.
  • The video must be hosted at a URL in the same way as a web image.
  • The video cannot be a URL to a website that contains a video player, it must be a direct URL to the source video.

For more information, see the Web Video Component page.

Designing headers

  • For configuring record views with a flush header, consider using a record header.
  • If you are using a fixed header, be sure to view your interface on multiple screen sizes to make sure the content is accessible on all devices. See the header content layout design guidance for more information.
  • If fixed header is selected in the header content layout, but it isn't selected for the record header, neither header will be fixed. See Design Record Views for more information.
  • To quickly configure a fixed header in a one-page portal, consider enabling the header bar. On sites and multipage portals, the header bar is always enabled.

Report titles in Tempo and embedded interfaces

  • This layout will not display the report title when viewed in Tempo and embedded interfaces.

Examples

To experiment with examples, copy and paste the expression into an interface object.

Billboard layout

This example uses a billboard layout within the header content layout. It displays the following interface.

A billboard header with "Finance Summary" and details in a bar overlay, an example section layout is at the bottom

See the page on Billboard Layouts for more information on billboards and the SAIL Design System: Billboard Layout for guidance on when to use each overlay style.

Copy and paste this example into an an interface object to experiment with it.

Fixed header

This example uses a fixed header within the header content layout. It displays the following interface.

gif of a fixed header with order details

Note that this pattern contains two empty a!cardLayout() components to help you see the scrolling behavior with a fixed header. These components have no other purpose.

See the SAIL Design System: Header Content Layout for more information on fixed headers.

Copy and paste this example into an interface object to experiment with it.
