##Simple Usage

###drag

dragEl.draggable();

###drop

dropEl.droppable();

Callbacks

###drag Drag supports three callbacks: start, drag, and stop. Start is fired at the start of the drag; drag during the drag; and stop when dragging stops.

dragEl.draggable({
  start: function (e, dragEl) {
    // your code here
  },
  drag: function (e, dragEl) {
    // your code here
  },
  stop: function (e, dragEl) {
    // your code here
  }
});

###drop At the moment drop supports one callback drop which fires when draggable element is dropped into droppable element. Drop callback can be used to validate a drop action by returning true - successful drop or false - unsuccessful drop.

dragEl.draggable({
  drop: function (e, dragEl, dropEl, pos) {
     // your code here
     return true;
  }
});

Events

###drag

It's possible to bind to three different events draggable:start, draggable:drag and draggable:stop emitted by draggable.

dragEl.on('draggable:start', function () {
  // your code goes here
});

###drop

Droppable emits one event droppable:drop when element is successfully dropped.

Options

###drag

####selector (class name)

Delegates to elements defined by selector instead of the main object. This is useful if you have a lot of draggable elements. Instead of binding to each element you can setup draggable to their parent and delegate to dragging elements by providing selector.

####context

Changes context in which callbacks will be executed.

####revert

When set to true draggable element goes back to its starting position in case when drop fails.

###drop

####context

Changes context in which callbacks will be executed.
