Tag name: <h:selectManyListbox>
UIComponent class: javax.faces.component.html.HtmlSelectManyListbox
Tag class: org.apache.myfaces.taglib.html.HtmlSelectManyListboxTag
Component type: javax.faces.HtmlSelectManyListbox
Component family: javax.faces.SelectMany
Renderer type: javax.faces.Listbox
Renderer class: org.apache.myfaces.renderkit.html.HtmlListboxRenderer
Allow the user to select zero or more items from a set of available options. This is presented as a listbox which allows multiple rows in the list to be selected simultaneously.
The set of available options is defined by adding child f:selectItem or f:selectItems components to this component.
The list is rendered as an HTML select element. The "multiple" attribute is set on the element and the size attribute is set to the provided value, defaulting to the number of items in the list if no value is provided. If the size is set to 1, then a "drop-down" list (aka "combo-box") is presented, though if this is the intention then a selectManyMenu should be used instead.
The value attribute must be a value-binding expression to a property of type List, Object array or primitive array. That "collection" is expected to contain objects of the same type as SelectItem.getValue() returns for the child SelectItem objects. On rendering, any child whose value is in the list will be selected initially. During the update phase, the property is set to contain a "collection" of values for those child SelectItem objects that are currently selected.
|accesskey||String||Yes||HTML: Sets the access key for this element.|
|binding||javax.faces.component.html.HtmlSelectManyListbox||Only EL||Identifies a backing bean property (of type UIComponent or appropriate subclass) to bind " + "to this component instance. This value must be an EL expression.|
|converter||javax.faces.convert.Converter||Yes||An expression that specifies the Converter for this component.
The value can either be a static value (ID) or an EL expression. When a static id is specified, an instance of the converter type registered with that id is used. When this is an EL expression, the result of evaluating the expression must be an object that implements the Converter interface.
|converterMessage||String||Yes||Text to be displayed to the user as an error message when conversion of a submitted value to the target type
|dir||String||Yes||HTML: The direction of text display, either 'ltr' (left-to-right) or 'rtl' (right-to-left).|
|disabled||boolean||Yes||HTML: When true, this element cannot receive focus.|
|disabledClass||String||Yes||The CSS class assigned to the label element for enabled choices.|
|enabledClass||String||Yes||The CSS class assigned to the label element for enabled choices.|
|id||String||Yes||Get a string which uniquely identifies this UIComponent within the scope of the nearest ancestor NamingContainer component. The id is not necessarily unique across all components in the current view.|
|immediate||boolean||Yes||A boolean value that identifies the phase during which action events should fire.
During normal event processing, action methods and action listener methods are fired during the "invoke application" phase of request processing. If this attribute is set to "true", these methods are fired instead at the end of the "apply request values" phase.
|label||String||Yes||A display name for this component.|
|lang||String||Yes||HTML: The base language of this document.|
|onblur||String||Yes||HTML: Specifies a script to be invoked when the element loses focus.|
|onchange||String||Yes||HTML: Specifies a script to be invoked when the element is modified.|
|onclick||String||Yes||HTML: Script to be invoked when the element is clicked.|
|ondblclick||String||Yes||HTML: Script to be invoked when the element is double-clicked.|
|onfocus||String||Yes||HTML: Specifies a script to be invoked when the element receives focus.|
|onkeydown||String||Yes||HTML: Script to be invoked when a key is pressed down over this element.|
|onkeypress||String||Yes||HTML: Script to be invoked when a key is pressed over this element.|
|onkeyup||String||Yes||HTML: Script to be invoked when a key is released over this element.|
|onmousedown||String||Yes||HTML: Script to be invoked when the pointing device is pressed over this element.|
|onmousemove||String||Yes||HTML: Script to be invoked when the pointing device is moved while it is in this element.|
|onmouseout||String||Yes||HTML: Script to be invoked when the pointing device is moves out of this element.|
|onmouseover||String||Yes||HTML: Script to be invoked when the pointing device is moved into this element.|
|onmouseup||String||Yes||HTML: Script to be invoked when the pointing device is released over this element.|
|onselect||String||Yes||HTML: Specifies a script to be invoked when the element is selected.|
|readonly||boolean||Yes||HTML: When true, indicates that this component cannot be modified by the user. The element may receive focus unless it has also been disabled.|
|rendered||boolean||Yes||A boolean value that indicates whether this component should be rendered. Default value: true.|
|required||boolean||Yes||A boolean value that indicates whether an input value is required.
If this value is true and no input value is provided by a postback operation, then the "requiredMessage" text is registered as a FacesMessage for the request, and validation fails.
Default value: false.
|requiredMessage||String||Yes||Text to be displayed to the user as an error message when this component is marked as "required" but no input data is present during a postback (ie the user left the required field blank).|
|size||int||Yes||see JSF Spec.|
|style||String||Yes||HTML: CSS styling instructions.|
|styleClass||String||Yes||The CSS class for this element. Corresponds to the HTML 'class' attribute.|
|tabindex||String||Yes||HTML: Specifies the position of this element within the tab order of the document.|
|title||String||Yes||HTML: An advisory title for this element. Often used by the user agent as a tooltip.|
|validator||javax.faces.el.MethodBinding||Only EL||A method-binding EL expression which is invoked during the validation phase for this component.
The invoked method is expected to check the submitted value for this component, and if not acceptable then report a validation error for the component.
The method is expected to have the prototypepublic void aMethod(FacesContext, UIComponent,Object)
|validatorMessage||String||Yes||Text which will be shown if validation fails.|
|value||Object||Yes||Gets The initial value of this component.|
|valueChangeListener||javax.faces.el.MethodBinding||Only EL||A method which is invoked during postback processing for the current view if the submitted value for this
component is not equal to the value which the "value" expression for this component returns.
The phase in which this method is invoked can be controlled via the immediate attribute.
