title: Creating a drag-and-drop designer UI with JQuery
body: <p>I want to create a web based UI which can do some basic drag drop and stuff. I am going to use it for I want to allow users to create some small certificates . Users can add text at places they want or upload images and than drop it at required places. I will than want to store those Images , text positions and width in a database based on which I will later generate a PDF file .</p>
  
  <p>Is there any better approach some one suggest ? Also is there any existing UI plugin which can make this easier ?</p>
