Methods

Events

Native HTML input elements are impossible to style consistently. This widget allows working around that limitation by positining the associated label on top of the hidden input, and emulating the checkbox or radio element itself using an (optional) icon. The original input still receives focus and all events, the label merely provides a themeable button on top.

Theming

The checkboxradio widget uses the jQuery UI CSS framework to style its look and feel. If checkboxradio specific styling is needed, the following CSS class names can be used for overrides or as keys for the classes option:

  • ui-checkboxradio: The input of type radio or checkbox. Will be hidden, with its associated label positioned on top.
    • ui-checkboxradio-label: The label associated with the input. If the input is checked, this will also get the ui-checkboxradio-checked class. If the input is of type radio, this will also get the ui-checkboxradio-radio-label class.
    • ui-checkboxradio-icon: If the icon option is enabled, the generated icon has this class.
    • ui-checkboxradio-icon-space: If the icon option is enabled, an extra element with this class as added between the text label and the icon.

Dependencies

Additional Notes:

  • This widget requires some functional CSS, otherwise it won't work. If you build a custom theme, use the widget's specific CSS file as a starting point.
