Question

I am using this http://jqueryui.com/demos/droppable/

But I have a problem dragging to a droppable that is smaller than the draggable.
It will not drop on the droppable, but on the top left of the droppable.

Is there any way around this?

Here is the code, thanks.

  $('.draggable').draggable({
    revert: 'invalid',
    revertDuration: 500,
    appendTo: 'body',

    helper: function(event, ui) {
      return $(this).clone().appendTo('body').css('zIndex', 5).show();
    },
    drag: function(event, ui) {
      $(ui.helper).removeClass("enlarge");
      $(ui.helper).addClass("thumbnail");
      $(this).hide();
    },
    stop: function(event, ui) {
      $(this).show();
      //$(this).addClass("enlarge");
      if ($(this).parent().hasClass("imageContainer")) {
        $(this).addClass("thumbnail");
      }
      else {
        $(this).addClass("enlarge");
      }
    },
    //cursorAt: { top: 30, left: 40 },
    delay: 100,
    refreshPositions: true
  });


  $('.imageContainer').droppable({
    accept: '.draggable',
    drop: function(event, ui) {
      ui.draggable.css({
        "position": "relative",
        "left": "0px",
        "top": "0px"
      });
      if ($(this).children().length == 0) {
        // ui.draggable.addClass("thumbnail");
        $(ui.draggable).appendTo(this);
        $(this).removeClass("border");
      }
    },
    over: function(event, ui) {
      ui.draggable.removeClass("enlarge");
      ui.draggable.addClass("thumbnail");
      $(this).addClass("border");
    },
    out: function(event, ui) {
      // ui.draggable.removeClass("zoomIn")
      $(this).removeClass("border");
    },

    tolerance: 'intersect'
  });

CSS:

.thumbnail  {
  height:60px;
  margin-right:10px;
  width:80px;
  z-index:1;
}
.enlarge {
  border:5px solid white;
  height:145px;
  width:195px;
}
Was it helpful?

Solution

  $('.draggable').draggable({
    revert: 'invalid',
    revertDuration: 500,
    appendTo: 'body',

    helper: function(event, ui) {
      return $(this).clone().appendTo('body').css('zIndex', 5).show();
    },
    drag: function(event, ui) {
   /* $(ui.helper).removeClass("enlarge");
      $(ui.helper).addClass("thumbnail");  */
      $(this).hide();
    },
    stop: function(event, ui) {
      $(this).show();
      //$(this).addClass("enlarge");
      if ($(this).parent().hasClass("imageContainer")) {
        $(this).addClass("thumbnail");
      }
      else {
        $(this).addClass("enlarge");
      }
    },
    //cursorAt: { top: 30, left: 40 },
    delay: 100,
    refreshPositions: true
  });

Try replacing your code with this block above and see if it comes close to what you want. It may not be perfect yet, but let's see if we can tackle one change at a time. What I'm hoping to observe is that it drops approximately like it should.
