Constructor

new OO.ui.CheckboxInputWidget([config]) #

CheckboxInputWidgets, like HTML checkboxes, can be selected and/or configured with a value. Note that these input widgets are best laid out in field layouts that use the inline alignment. For more information, please see the OOUI documentation on MediaWiki.

This widget can be used inside an HTML form, such as a OO.ui.FormLayout.

Example

// An example of selected, unselected, and disabled checkbox inputs.
    const checkbox1 = new OO.ui.CheckboxInputWidget( {
            value: 'a',
             selected: true
        } ),
        checkbox2 = new OO.ui.CheckboxInputWidget( {
            value: 'b'
        } ),
        checkbox3 = new OO.ui.CheckboxInputWidget( {
            value:'c',
            disabled: true
        } ),
        // Create a fieldset layout with fields for each checkbox.
        fieldset = new OO.ui.FieldsetLayout( {
            label: 'Checkboxes'
        } );
    fieldset.addItems( [
        new OO.ui.FieldLayout( checkbox1, { label: 'Selected checkbox', align: 'inline' } ),
        new OO.ui.FieldLayout( checkbox2, { label: 'Unselected checkbox', align: 'inline' } ),
        new OO.ui.FieldLayout( checkbox3, { label: 'Disabled checkbox', align: 'inline' } ),
    ] );
    $( document.body ).append( fieldset.$element );

This method is called by OO.ui.LabelWidget and OO.ui.FieldLayout. It should not be called directly.
