Render an HTML checkbox list.

Decode Behavior

See the "Decode Behavior for UISelectMany Components" section.

Encode Behavior

Render a "table" element. If the "styleClass" is specified, render the value of the "styleClass" attribute as the value of the "class" attribute on the "table" element. If the "style", or "border" attributes are specified, pass them thru and render their values as the "style" and "border" attributes on the "table", respectively. If the "layout" attribute is specified, and its value is "pageDirection", render the children elements vertically, otherwise horizontally, in the table. If any of the children are an instance of SelectItemGroup, render them as a nested table. Each of the children are ultimately rendererd as follows. Render an "input" element of "type" "checkbox" for each child component. Render the "name" attribute on the "input" element with the value of the `clientId` of the component. Render an "id" attribute on the "input" element. Each "id" value must be unique. If the current SelectItem.isDisabled() returns true, render "disabled" as the value of the "disabled" attribute. Close out the "input" element. Render a "label" element. Render the "for" attribute of the "label" element whose value is the corresponding "input" element's "id" value. If the current checkbox would be rendered as being checked, and there is a "selectedClass" attribute, append a space, followed by the value of the "selectedClass" attribute to any existing "class" attribute value on the label element. Otherwise, render the value of the "selectedClass" attribute as the value of the "class" attribute on the label element. If the current checkbox would be rendered as being not checked, and there is a "unselectedClass" attribute, append a space, followed by the value of the "unselectedClass" attribute to any existing "class" attribute value on the label element. Otherwise, render the value of the "unselectedClass" attribute as the value of the "class" attribute on the label element. If the current checkbox would be rendered as being disabled, and there is a "disabledClass" attribute, append a space, followed by the value of the "disabledClass" attribute to any existing "class" attribute value on the label element. Otherwise, render the value of the "disabledClass" attribute as the value of the "class" attribute on the label element. If the current checkbox would be rendered as being enabled, and there is an "enabledClass" attribute, append a space, followed by the value of the "enabledClass" attribute to any existing "class" attribute value on the label element. Otherwise, render the value of the "enabledClass" attribute as the value of the "class" attribute on the label element. Close out the starting "label" element and render the label value from SelectItem.getLabel(). Close out the "label" element. As an exception to the general rules about how to handle the "id" attribute, render it as an attribute on the outer "table" element, the value of which is the `clientId` of the component per the rules at the beginning of this specification. The value of the current SelectItem is rendered as the value of the "value" attribute. Coerce the value of the currently rendered child to the type of the parent UISelectMany value following the Expression Language coercion rules, before comparing the values. If the value of the enclosing UISelectMany matches the current value, render "checked" as the value of the "checked" attribute. See the "Rendering the option elements" specification for `ListboxRenderer` for more detail on how to render the "option" elements in this renderer. Note that this renderer does not support `SelectItemGroup` elements, so the text that describes the rendering of `SelectItemGroup` does not apply to this renderer.

Attributes
Name | Required | Request-time | Type | Description
converter | false | false | `javax.el.ValueExpression` (must evaluate to `javax.faces.convert.Converter`) | Converter instance registered with this component.
converterMessage | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | A ValueExpression enabled attribute that, if present, will be used as the text of the converter message, replacing any message that comes from the converter.
id | false | true | `java.lang.String` | The component identifier for this component. This value must be unique within the closest parent component that is a naming container.
immediate | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | Flag indicating that this component's value must be converted and validated immediately (that is, during Apply Request Values phase), rather than waiting until Process Validations phase.
rendered | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | Flag indicating whether or not this component should be rendered (during Render Response Phase), or processed on any subsequent form submit. The default value for this property is true.
required | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | Flag indicating that the user is required to provide a submitted value for this input component.
requiredMessage | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | A ValueExpression enabled attribute that, if present, will be used as the text of the validation message for the "required" facility, if the "required" facility is used.
validator | false | false | `javax.el.MethodExpression` (signature must match `void validate(javax.faces.context.FacesContext, javax.faces.component.UIComponent, java.lang.Object)`) | MethodExpression representing a validator method that will be called during Process Validations to perform correctness checks on the value of this component. The expression must evaluate to a public method that takes FacesContext, UIComponent, and Object parameters, with a return type of void.
validatorMessage | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | A ValueExpression enabled attribute that, if present, will be used as the text of the validator message, replacing any message that comes from the validator.
value | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.Object`) | The current value of this component.
valueChangeListener | false | false | `javax.el.MethodExpression` (signature must match `void valueChange(javax.faces.event.ValueChangeEvent)`) | MethodExpression representing a value change listener method that will be notified when a new value has been set for this input component. The expression must evaluate to a public method that takes a `ValueChangeEvent` parameter, with a return type of void, or to a public method that takes no arguments with a return type of void. In the latter case, the method has no way of easily knowing what the new value is, but this can be useful in cases where a notification is needed that "this value changed".
accesskey | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | Access key that, when pressed, transfers focus to this element.
border | false | false | `javax.el.ValueExpression` (must evaluate to `int`) | Width (in pixels) of the border to be drawn around the table containing the options list.
collectionType | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | Optional attribute that is a literal string that is the fully qualified class name of a concrete class that implements `java.util.Collection`, or an EL expression that evaluates to either 1. such a String, or 2. the `Class` object itself.
dir | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | Direction indication for text that does not inherit directionality. Valid values are "LTR" (left-to-right) and "RTL" (right-to-left).
disabled | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | Flag indicating that this element must never receive focus or be included in a subsequent submit. A value of false causes no attribute to be rendered, while a value of true causes the attribute to be rendered as disabled="disabled".
disabledClass | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | CSS style class to apply to the rendered label on disabled options.
