* The FlaggedElement class is an attribute mixin, meaning that it is used to add

* a ‘flags’ property assigned the name (or an array of names) of styling flags,
* which are used to customize the look and feel of a widget to better describe its
* importance and functionality.
*
* The library currently contains the following styling flags for general use:
*
* - **progressive**: Progressive styling is applied to convey that the widget will move the user
* forward in a process.
* - **destructive**: Destructive styling is applied to convey that the widget will remove
* something.
*
* {@link OO.ui.ActionWidget ActionWidgets}, which are a special kind of button that execute an
* action, use these flags: **primary** and **safe**.
* Please see the [OOUI documentation on MediaWiki][1] for more information.
*
* [1]: https://www.mediawiki.org/wiki/OOUI/Elements/Flagged

*
* @example
* // FlaggedElement is mixed into ButtonWidget to provide styling flags
* const button1 = new OO.ui.ButtonWidget( {
* label: 'Progressive',
* flags: 'progressive'
* } ),

/**
* PopupWidget is a container for content. The popup is overlaid and positioned absolutely.
* By default, each popup has an anchor that points toward its origin.
* Please see the [OOUI documentation on MediaWiki.org][1] for more information and examples.
*
* Unlike most widgets, PopupWidget is initially hidden and must be shown by calling #toggle.
*
* [1]: https://www.mediawiki.org/wiki/OOUI/Widgets/Popups
*
* @example
* // A PopupWidget.
* const popup = new OO.ui.PopupWidget( {
* $content: $( '<p>Hi there!</p>' ),
* padded: true,
* width: 300
* } );
*
* $( document.body ).append( popup.$element );
* // To display the popup, toggle the visibility to 'true'.
* popup.toggle( true );
*
* @class
* @extends OO.ui.Widget
* @mixes OO.ui.mixin.IconElement
* @mixes OO.ui.mixin.LabelElement
* @mixes OO.ui.mixin.ClippableElement
* @mixes OO.ui.mixin.FloatableElement
*
* @constructor
* @param {Object} [config] Configuration options
* @param {number|null} [config.width=320] Width of popup in pixels. Pass `null` to use automatic width.
* @param {number|null} [config.height=null] Height of popup in pixels. Pass `null` to use automatic height.
* @param {boolean} [config.anchor=true] Show anchor pointing to origin of popup
* @param {string} [config.position='below'] Where to position the popup relative to $floatableContainer
* 'above': Put popup above $floatableContainer; anchor points down to the horizontal center
* of $floatableContainer
* 'below': Put popup below $floatableContainer; anchor points up to the horizontal center
* of $floatableContainer
* 'before': Put popup to the left (LTR) / right (RTL) of $floatableContainer; anchor points
* endwards (right/left) to the vertical center of $floatableContainer
* 'after': Put popup to the right (LTR) / left (RTL) of $floatableContainer; anchor points
* startwards (left/right) to the vertical center of $floatableContainer
* @param {string} [config.align='center'] How to align the popup to $floatableContainer
* 'forwards': If position is above/below, move the popup as far endwards (right in LTR, left in
* RTL) as possible while still keeping the anchor within the popup; if position is before/after,
* move the popup as far downwards as possible.
* 'backwards': If position is above/below, move the popup as far startwards (left in LTR, right in
* RTL) as possible while still keeping the anchor within the popup; if position is before/after,
* move the popup as far upwards as possible.
* 'center': Horizontally (if position is above/below) or vertically (before/after) align the
* center of the popup with the center of $floatableContainer.
* 'force-left': Alias for 'forwards' in LTR and 'backwards' in RTL
* 'force-right': Alias for 'backwards' in RTL and 'forwards' in LTR
* @param {boolean} [config.autoFlip=true] Whether to automatically switch the popup's position between
* 'above' and 'below', or between 'before' and 'after', if there is not enough space in the
* desired direction to display the popup without clipping
* @param {jQuery} [config.$container] Constrain the popup to the boundaries of the specified container.
* See the [OOUI docs on MediaWiki][3] for an example.
* [3]: https://www.mediawiki.org/wiki/OOUI/Widgets/Popups#containerExample
* @param {number} [config.containerPadding=10] Padding between the popup and its container, specified as a
* number of pixels.
* @param {jQuery} [config.$content] Content to append to the popup's body
* @param {jQuery} [config.$footer] Content to append to the popup's footer
* @param {boolean} [config.autoClose=false] Automatically close the popup when it loses focus.
* @param {jQuery} [config.$autoCloseIgnore] Elements that will not close the popup when clicked.
* This config option is only relevant if #autoClose is set to `true`. See the
* [OOUI documentation on MediaWiki][2] for an example.
* [2]: https://www.mediawiki.org/wiki/OOUI/Widgets/Popups#autocloseExample

* MenuSelectWidget is a {@link OO.ui.SelectWidget select widget} that contains options and

* See {@link OO.ui.DropdownWidget DropdownWidget},
* {@link OO.ui.ComboBoxInputWidget ComboBoxInputWidget}, and
* {@link OO.ui.mixin.LookupElement LookupElement} for examples of widgets that contain menus.
* MenuSelectWidgets themselves are not instantiated directly, rather subclassed
* and customized to be opened, closed, and displayed as needed.
*
* By default, menus are clipped to the visible viewport and are not visible when a user presses the
* mouse outside the menu.
*
* Menus also have support for keyboard interaction:
*
* - Enter/Return key: choose and select a menu option
* - Up-arrow key: highlight the previous menu option
* - Down-arrow key: highlight the next menu option
* - Escape key: hide the menu
*
* Unlike most widgets, MenuSelectWidget is initially hidden and must be shown by calling #toggle.
*

/**
* 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][1] for examples and more information.
