How to position jquery ui dialog box with respect to a div element inside the body?

Syntax: $( ". selector" ). dialog({ position: { my: "left top", at: "left bottom", of: button } });
position() method allows us to retrieve the current position of an element (specifically its margin box) relative to the offset parent (specifically its padding box, which excludes margins and borders). Contrast this with . offset() , which retrieves the current position relative to the document.
Although both methods have some similarities, but the jQuery offset() method is different from the jQuery position() method. The offset() method retrieves the current position relative to the document, whereas the position() method retrieves the current position of an element relative to the parent element.
The jQuery UI dialog method is used to create a basic dialog window which is positioned into the viewport and protected from page content. It has a title bar and a content area, and can be moved, resized and closed with the 'x' icon by default. Syntax: You can use the dialog ()method in two forms: ADVERTISEMENT.
Perhaps this might get you the idea how to do it:
HTML:
<div id="one" class="divs"></div>
<div id="two" class="divs"></div>
CSS:
.divs {
float: left;
height: 48px;
width: 80px;
border: 1px solid #55f;
}
JS:
$(document).ready(function(){
var $div = $('#two');
var left = $div.offset().left;
var top= $div.offset().top;
$('<p>Some dialog</p>').dialog({position: [left + 20, top + 20]});
});
Here is the link to demo.
jQuery offset() returns element postion relative to document, while position() returns relative to offset parent.
