OO.ui.FieldLayout

Extends

Constructor

new OO.ui.FieldLayout(fieldWidget, [config]) #

FieldLayouts are used with OO.ui.FieldsetLayout. Each FieldLayout requires a field-widget, which is a widget that is specified by reference before any optional configuration settings.

Field layouts can be configured with help text and/or labels. Labels are aligned in one of four ways:

  • left: The label is placed before the field-widget and aligned with the left margin. A left-alignment is used for forms with many fields.
  • right: The label is placed before the field-widget and aligned to the right margin. A right-alignment is used for long but familiar forms which users tab through, verifying the current field with a quick glance at the label.
  • top: The label is placed above the field-widget. A top-alignment is used for brief forms that users fill out from top to bottom.
  • inline: The label is placed after the field-widget and aligned to the left. An inline-alignment is best used with checkboxes or radio buttons.

Help text can either be:

  • accessed via a help icon that appears in the upper right corner of the rendered field layout, or
  • shown as a subtle explanation below the label.

If the help text is brief, or is essential to always expose it, set helpInline to true. If it is long or not essential, leave helpInline to its default, false.

Please see the OOUI documentation on MediaWiki for examples and more information.

Parameters:

Name Type Attributes Description
fieldWidget OO.ui.Widget

Field widget
config Object optional

Configuration options

Properties:
Name Type Attributes Default Description
align string optional
 'left'

Alignment of the label: 'left', 'right', 'top' or 'inline'
errors Array optional

Error messages about the widget, which will be displayed below the widget.
warnings Array optional

Warning messages about the widget, which will be displayed below the widget.
successMessages Array optional

Success messages on user interactions with the widget, which will be displayed below the widget. The array may contain strings or OO.ui.HtmlSnippet instances.
notices Array optional

Notices about the widget, which will be displayed below the widget. The array may contain strings or OO.ui.HtmlSnippet instances. These are more visible than help messages when helpInline is set, and so might be good for transient messages.
help string | OO.ui.HtmlSnippet optional

Help text. When help text is specified and helpInline is false, a "help" icon will appear in the upper-right corner of the rendered field; clicking it will display the text in a popup. If helpInline is true, then a subtle description will be shown after the label.
helpInline boolean optional
 false

Whether or not the help should be inline, or shown when the "help" icon is clicked.
$overlay jQuery optional

Passed to OO.ui.PopupButtonWidget for help popup, if help is given. See https://www.mediawiki.org/wiki/OOUI/Concepts#Overlays.
