JavaScript DHTML/YUI Library/Drag Drop
Содержание
- 1 Basic Drag and Drop
- 2 Create a list that can have the order changed with the Drag & Drop Utility.
- 3 Drag and drop Interaction Mode: Intersect
- 4 Drag and drop Interaction Mode: Point
- 5 Drag and drop using a proxy element.
- 6 Drag and drop: Using Interaction Groups
- 7 Implement a circular drag object
- 8 Implement a custom click validator to make a circular drag and drop implementation.
- 9 Keep draggable elements from being dragged out of a region.
- 10 Keeping the dragged element on top of the others by changing its z-index property during the drag.
- 11 This example shows the use of the drag shim when dragging nodes over other troublesome nodes.
- 12 Use drag handles to control the specific places within an element from which a drag can be initiated.
- 13 Use ghosting and manipulate the proxy element.
