title: My SQL workbench creating many to many relationship in EER diagram
body: <p>so I was trying to create an EER diagram from a database model and I wanted to do something similar to this.</p>
  
  <p>Say I have a table named Bag and another one named Address. I already set the PK in Address to be the FK in Bag, when creating the diagram I found that I cannot find the option "many to many" in mySQL workbench. <a href="https://i.stack.imgur.com/vtLBw.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vtLBw.png" alt="see the screenshot I took"></a></p>
  
  <p>I wonder what is causing this to happen(maybe I'm doing something wrong but right now I cannot think of any reasonable explanation...)</p>
  
  <p>Hopefully someone can shed some light on this.</p>
  
  <p>Thanks!</p>
