Draggable.create(".box", {
    type: "x,y",
    edgeResistance: 0.65,
    bounds: "#container",
    throwProps: true
});

Spin

Set Draggable's type to "rotation" and watch what happens (grab the knob below and spin it). ThrowPropsPlugin tracks the velocity of the rotation and continues when you release your mouse (or finger for touch devices), gliding to a stop naturally. Activate the "Snap to 90-degree increments" option to see how easy it is to make it always land at certain rotational values without any jerking or awkwardness.

Snap to 90-degree increments

Code

Draggable.create("#knob", {type: "rotation", throwProps: true});

Draggable.create("#container", {type:"scroll", throwProps:true, edgeResistance:0.35});

Draggable.create("#scroller", {type:"scroll", edgeResistance:0.5, throwProps:true}); 

Features

• Touch enabled - works great on tablets, phones, and desktop browsers.
• Incredibly smooth - GPU-accelerated and requestAnimationFrame-driven for ultimate performance. Compared to other options out there, Draggable just feels far more natural and fluid, particularly when imposing bounds and momentum.
• Momentum-based animation - if you have ThrowPropsPlugin loaded, you can simply set throwProps:true in the config object and it'll automatically apply natural, momentum-based movement after the mouse/touch is released, causing the object to glide gracefully to a stop. You can even control the amount of resistance, maximum or minimum duration, etc.
• Complex snapping made easy - snap to points within a certain radius (see example), or feed in an array of values and it'll select the closest one, or implement your own custom logic in a function. Ultimate flexibility. You can have things live-snap (while dragging) or only on release (even with momentum applied, thanks to ThrowPropsPlugin)!
• Impose bounds - tell a draggable element to stay within the bounds of another DOM element (a container) as in bounds:"#container" or define bounds as coordinates like bounds:{top:100, left:0, width:1000, height:800} or specific maximum/minimum values like bounds:{minRotation:0, maxRotation:270}.
• Sense overlaps with hitTest() - see if one element is overlapping another and even set a tolerance threshold (like at least 20 pixels or 25% of either element's total surface area) using the super-flexible Draggable.hitTest() method. Feed it a mouse event and it'll tell you if the mouse is over the element. See http://codepen.io/GreenSock/pen/GFBvn for a simple example.
• Define a trigger element - maybe you want only a certain area to trigger the dragging (like the top bar of a window) - it's as simple as trigger:"#topBar", for example.
• Drag position, rotation, or scroll - lots of drag types to choose from: "x,y" | "top,left" | "rotation" | "scroll" | "x" | "y" | "top" | "left" | "scrollTop" | "scrollLeft"
• Lock movement along a certain axis - set lockAxis:true and Draggable will watch the direction the user starts to drag and then restrict it to that axis. Or if you only want to allow vertical or horizontal movement, that's easy too using the type ("top", "y" or "scrollTop" only allow vertical movement; "x", "left", or "scrollLeft" only allow horizontal movement).
• Rotation honors transform origin - by default, spinnable elements will rotate around their center, but you can set transformOrigin to something else to make the pivot point be elsewhere. For example, if you call TweenLite.set(yourElement, {transformOrigin:"top left"}) before dragging, it will rotate around its top left corner. Or use % or px. Whatever is set in the element's css will be honored.
• Rich callback system and event dispatching - you can use any of the following callbacks: onPress, onDragStart, onDrag, onDragEnd, onRelease,, onLockAxis, and onClick. Inside the callbacks, "this" refers to the Draggable instance itself, so you can easily access its "target" or bounds, etc. If you prefer event listeners instead, Draggable dispatches events too so you can do things likeyourDraggable.addEventListener("dragend", yourFunc);
• Works great with SVG
• Even works in transformed containers! Got a Draggable inside a rotated/scaled container? No problem. No other tool handles this properly that we've seen.
• Auto-scrolling, even in multiple containers - set autoScroll:1 for normal-speed auto scrolling, or autoScroll:2 would scroll twice as fast, etc. The closer you move toward the edge, the faster scrolling gets. See a demo here (added in version 0.12.0)
• Sense clicks when the element moves less than 3 pixels - a common challenge is figuring out when a user is trying to click/tap an object rather than drag it, so if the mouse/touch moves less than 3 pixels from its starting position, it will be interpreted as a "click" and the onClick callback will be called (and a "click" event dispatched) without actually moving the element. You can define a different threshold using minimumMovement config property, like minimumMovement:6 for 6 pixels.
• All major browsers are supported including IE9+. IE8 lacks hitTest() support.
