I have tried to make my sample as basic as possible.
I have looked at all the examples i could find , but can not make this work. I have to be missing something very obvious
I have two container divs socialSidebar and content
I am trying to drag any one of the draggable divs from socialSidebar to eventContent
but for some reason only "map" is draggable

any help will be Greatly appreciated.

You can have the same ID for multiple element. ID must be unique in a document. So use a different ID OR a class (the same on, no problem)
check this : http://jsfiddle.net/zNraJ/2/

        <div id="draggable1" class="ui-widget-content" >map</div>
        <div id="draggable2" class="ui-widget-content" >countdown</div>
        <div id="draggable3" class="ui-widget-content" >email</div>

Open in new window


$( "#draggable1,#draggable2,#draggable3" ).draggable();

Open in new window


    #draggable1,#draggable2,#draggable3{
        border: 1px solid red;
        width: 200px;
        margin: 10px;
        cursor: move;
    }

using the same class (ui-widget-content) : http://jsfiddle.net/zNraJ/3/

        <div class="ui-widget-content" >map</div>
        <div class="ui-widget-content" >countdown</div>
        <div class="ui-widget-content" >email</div>

Open in new window


$( ".ui-widget-content" ).draggable();

Open in new window


    .ui-widget-content{
        border: 1px solid red;
        width: 200px;
        margin: 10px;
        cursor: move;
    }

Definition and Usage

The id attribute specifies a unique id for an HTML element (the id attribute value must be unique within the HTML document).

The id attribute can be used to point to a style in a style sheet.

The id attribute can also be used by a JavaScript (via the HTML DOM) to make changes to the HTML element with the specific id.

That is why i was confused.
The jquery examples all had dup id's which did not make sense to what i knew
http://jqueryui.com/demos/droppable/ but they do have different classes
