3067 * a ‘flags’ property assigned the name (or an array of names) of styling flags,
3068 * which are used to customize the look and feel of a widget to better describe its
3069 * importance and functionality.
3071 * The library currently contains the following styling flags for general use:
3073 * - **progressive**: Progressive styling is applied to convey that the widget will move the user forward in a process.
3074 * - **destructive**: Destructive styling is applied to convey that the widget will remove something.
3075 * - **constructive**: Constructive styling is applied to convey that the widget will create something.
3077 * The flags affect the appearance of the buttons:
3080 * // FlaggedElement is mixed into ButtonWidget to provide styling flags
3081 * var button1 = new OO.ui.ButtonWidget( {
3082 * label: 'Constructive',

10747 * FieldLayouts are used with OO.ui.FieldsetLayout. Each FieldLayout requires a field-widget,
10748 * which is a widget that is specified by reference before any optional configuration settings.
10750 * Field layouts can be configured with help text and/or labels. Labels are aligned in one of four ways:
10752 * - **left**: The label is placed before the field-widget and aligned with the left margin.
10753 * A left-alignment is used for forms with many fields.
10754 * - **right**: The label is placed before the field-widget and aligned to the right margin.
10755 * A right-alignment is used for long but familiar forms which users tab through,
10756 * verifying the current field with a quick glance at the label.
10757 * - **top**: The label is placed above the field-widget. A top-alignment is used for brief forms
10758 * that users fill out from top to bottom.
10759 * - **inline**: The label is placed after the field-widget and aligned to the left.
10760 * An inline-alignment is best used with checkboxes or radio buttons.
10762 * Help text is accessed via a help icon that appears in the upper right corner of the rendered field layout.
10763 * Please see the [OOjs UI documentation on MediaWiki] [1] for examples and more information.

11230 * Only widgets from the {@link OO.ui.InputWidget InputWidget} family support form submission. It
11231 * includes standard form elements like {@link OO.ui.CheckboxInputWidget checkboxes}, {@link
11232 * OO.ui.RadioInputWidget radio buttons} and {@link OO.ui.TextInputWidget text fields}, as well as
11233 * some fancier controls. Some controls have both regular and InputWidget variants, for example
11234 * OO.ui.DropdownWidget and OO.ui.DropdownInputWidget – only the latter support form submission and
11235 * often have simplified APIs to match the capabilities of HTML forms.
