title: (jQuery plugin to) drag & drop answers in multiple choice quiz
body: <p>I'm making a webpage where the user has to connect elements from two lists in a quiz. For example, imagine a quiz question where you have two lists, one with countries and one with capitals, and the user has to connect the capitals to the correct countries.</p>
  
  <p>Preferably, there should be a way for the user to drag the elements from the second list to an area next to the elements of the first list. Like this:</p>
  
  <p><img src="https://i.stack.imgur.com/OHFyQ.png" alt="example image"></p>
  
  <p>Here, you would drag the blue boxes into the gray rectangles.</p>
  
  <p>Is there a jQuery plugin or other JavaScript library that does something like this already? Or do I have to implement it myself? If so, does anyone have some pointers to articles describing solutions to similar problems, or ideas on how one can best solve this?</p>
