Answer 1

Here is some information about the DragDrop tags.
These tags allow you to easily add drag and drop functionality to a portal UI. The library is made up of 3 tags.
1. dragDropScript - This tag is used to include the necessary DragDrop Javascript libraries into the page. It must be included on the page before any other DragDrop tags are used.
2. draggableResource - This tag identifies a draggable resource on the page. It takes two attributes: resourceId and resourceName.
The resourceId identifies the resource that is being dragged. This should be an id that can be used by the underlying business logic to uniquely identify the resource.
The resourceName is a string that is the representative name of the dragged resource.
3. resourceDropZone - This tag identifies an area where draggable resources can be dropped. It takes the following attirbutes: targetId, jsFunctionCall, pageFlowAction, formAction.
The targetId uniquely identifies the drop target.
Only one of the following attributes is required: jsFunctionCall, pageFlowAction, or formAction. The jsFunctionCall takes precedence, then pageFlowAction, and finally formAction. These attributes represent what will occur when the resource is dropped on the drop zone.
If you set up the tag to execute a pageflow action upon dropping the resource, the action code can retrieve the dragged sourceId and the drop targetId using the following code:
String sourceId = getRequest().getParameter("sourceId");
String targetId = getRequest().getParameter("targetId");
Hope that helps.
