## RichFaces
Tag dragSupport

The <rich:dragSupport> component defines a subtree of the component tree as draggable for drag-and-drop operations. Within such a "drag zone", you can click the mouse button on an item and drag it to any component that supports drop operations (a "drop zone"). It encodes all the necessary JavaScript for supporting drag-and-drop operations.

Attributes
Name | Required | Request-time | Type | Description
action | false | false | `javax.el.MethodExpression` (signature must match `java.lang.Object action()`) | MethodBinding pointing at the application action to be invoked, if this UIComponent is activated by you, during the Apply Request Values or Invoke Application phase of the request processing lifecycle, depending on the value of the immediate property
actionListener | false | false | `javax.el.MethodExpression` (signature must match `void actionListener(javax.faces.event.ActionEvent)`) | MethodBinding pointing at method accepting an ActionEvent with return type void
ajaxSingle | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | boolean attribute which provides possibility to limit JSF tree processing(decoding, conversion/validation, value applying) to the component which send the request only
binding | false | false | `javax.el.ValueExpression` (must evaluate to `javax.faces.component.UIComponent`) | The attribute takes a value-binding expression for a component property of a backing bean
bypassUpdates | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | If "true", after process validations phase it skips updates of model beans on a force render response. It can be used for validating components input
data | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.Object`) | Serialized (on default with JSON) data passed on the client by a developer on AJAX request. It's accessible via "data.foo" syntax
disableDefault | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | Disable default action for target event (append "return false;" to JavaScript)
dragIndicator | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | Id of a component that is used as drag pointer during the drag operation
dragListener | false | false | `javax.el.MethodExpression` (signature must match `void dragListener(org.richfaces.event.DragEvent)`) | MethodBinding representing an action listener method that will be notified after drag operation
dragType | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | A drag zone type that is used for zone definition, which elements can be accepted by a drop zone
dragValue | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.Object`) | Data to be sent to a drop zone after a drop event
eventsQueue | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | Name of requests queue to avoid send next request before complete other from same event. Can be used to reduce number of requests of frequently events (key press, mouse move etc.)
focus | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | id of element to set focus after request completed on client side
grabCursors | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | List of comma separated cursors that indicates then you can grab and drag an object
grabbingCursors | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | list of comma separated cursors that indicates then the you has grabbed something
id | false | false | `java.lang.String` | Every component may have a unique id that is automatically created if omitted
ignoreDupResponses | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | Attribute allows to ignore an Ajax Response produced by a request if the newest 'similar' request is in a queue already. ignoreDupResponses="true" does not cancel the request while it is processed on the server, but just allows to avoid unnecessary updates on the client side if the response isn't actual now
immediate | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | True means, that the default ActionListener should be executed immediately (i.e. during Apply Request Values phase of the request processing lifecycle), rather than waiting until the Invoke Application phase
limitToList | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | If "true", then of all AJAX-rendered on the page components only those will be updated, which ID's are passed to the "reRender" attribute of the describable component. "false"-the default value-means that all components with ajaxRendered="true" will be updated.
onbeforedomupdate | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | JavaScript code for call before DOM has been updated on client side
oncomplete | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | JavaScript code for call after request completed on client side
ondragend | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | A JavaScript event handler called after a drag operation
ondragstart | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | A JavaScript event handler called before drag operation
ondropout | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | A JavaScript event handler called after a out operation
ondropover | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | A JavaScript event handler called after a drop operation
process | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.Object`) | Id['s] (in format of call UIComponent.findComponent()) of components, processed at the phases 2-5 in case of AjaxRequest caused by this component. Can be single id, comma-separated list of Id's, or EL Expression with array or Collection
reRender | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.Object`) | Id['s] (in format of call UIComponent.findComponent()) of components, rendered in case of AjaxRequest caused by this component. Can be single id, comma-separated list of Id's, or EL Expression with array or Collection
rendered | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | If "false", this component is not rendered
requestDelay | false | false | `javax.el.ValueExpression` (must evaluate to `int`) | Attribute defines the time (in ms.) that the request will be wait in the queue before it is ready to send. When the delay time is over, the request will be sent to the server or removed if the newest 'similar' request is in a queue already
similarityGroupingId | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | If there are any component requests with identical IDs then these requests will be grouped.
status | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | ID (in format of call UIComponent.findComponent()) of Request status component
timeout | false | false | `javax.el.ValueExpression` (must evaluate to `int`) | Response waiting time on a particular request. If a response is not received during this time, the request is aborted
value | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.Object`) | The current value for this component
