jQuery Draggable and overflow issue [closed]

Question

I am having an undesired effect when I drag a div from a container div which is set as overflow: scroll.

I have found an example of someone else where they have had the issue but I have been unable to find a resolution

Example on Paste bin

What happens is that the scroll is just increased, I can see why this would be the desired behaviour if you wanted to drag to a destination within the scrollable div but I want to be able to take it outside of its scrolling grasp.

Answer 1

It certainly pays to pay attention to the documentation

http://docs.jquery.com/UI/Draggable#option-scroll

scroll

Type: Boolean
Default: true
If set to true, container auto-scrolls while dragging.

Answer 2

I had a similar problem enabling a drag between two overflow-auto divs. With the help of the previous answers, I found that this combination works for me (Safari 5.0.3, jquery-1.4.4, jquery-ui-1.8.7):

appendTo: 'body',
containment: 'window',
scroll: false,
helper: 'clone'

Answer 3

appendTo

Element, SelectorDefault:'parent'

The element passed to or selected by the appendTo option will be used as the draggable helper's container during dragging. By default, the helper is appended to the same container as the draggable.

Code examples Initialize a draggable with the appendTo option specified.

$('.selector').draggable({ appendTo: 'body' });

Answer 4

The clone solution it works, but has two problems.

First: the clone are append to the body. Depending of your css, your element can change the styles, since before it starts, it's inside of another element and during the dragging, it will be directly on body element.

Second: Sometimes the element MUST move, and the clone let the object there.

So, the solution for this problems is:

$('.selector').draggable({
    helper: 'clone',
    start: function(){
        $(this).hide();             
    },
    stop: function(){
        $(this).show()
    }
});

Answer 5

Setting the scroll option does not stop children from being hidden in the overflow area. I have come up with a work-a-round that uses the helper option. Check it out:

Also here is a reference to another post I made:

jquery ui draggable elements not 'draggable' outside of scrolling div

Answer 6

You can also specify which types of elements you don't want to include.

<div class="draggable"> 
    <h2>This will drag the div</h2>
    <ul>
       <li>This won't drag the div</li>
    </ul>
</div>

Apply this cancel property to ignore the event in specified child elements

$('.draggable').draggable({cancel : 'ul'});
