helpers\BaseHtml checkboxList()

The name attribute of each checkbox.

The selected value(s). String for single or array for multiple selection(s).

The data item used to generate the checkboxes. The array keys are the checkbox values, while the array values are the corresponding labels.

Options (name => config) for the checkbox list container tag. The following options are specially handled:

• tag: string|false, the tag name of the container element. False to render checkbox without container. See also tag().
• unselect: string, the value that should be submitted when none of the checkboxes is selected. By setting this option, a hidden input will be generated.
• encode: boolean, whether to HTML-encode the checkbox labels. Defaults to true. This option is ignored if item option is set.
• separator: string, the HTML code that separates items.
• itemOptions: array, the options for generating the checkbox tag using checkbox().

• item: callable, a callback that can be used to customize the generation of the HTML code corresponding to a single item in $items. The signature of this callback must be:

  function ($index, $label, $name, $checked, $value)
  

  where $index is the zero-based index of the checkbox in the whole list; $label is the label for the checkbox; and $name, $value and $checked represent the name, value and the checked status of the checkbox input, respectively.

See renderTagAttributes() for details on how attributes are being rendered.
