Adding an option to display a badge with the number of dragged items if dragging multiple

That's great! I will try to find some time to merge this during the weekend. On the mean time let me share some of my thoughts:

• how about using a namespaced name for the sortable option, similarly to the way ui-sortable does it for it's extra (non jquery ui) options? I was thinking about something like 'ui-selection-count' ?
• how about using data-selection-count as the attribute on the helper element?
• until now there was no embedded css file in this project. We should either move the newly added css to the codepen example itself and drop the css file OR move the basic selected classes to the css file as well. To be honest I prefer the first approach, letting the user copy paste any required css classes from the example, keeping this a js only directive (like ui-sortable).

Hi, thanks for your comments. I pushed some updates to the pull request. Let me know if you want me to change something else.

That's great & removes the need for an extra option! I will merge it today (I hope).

Great PR :+1: with just +-12 diff! The only thing that we can improve is the way that we retrieve the sortableOptions. Ideally this should be done in the helper callback, but we also have to find a way to make the implementation DebugInfo disabled compliant.
