title: manipulate svg file within a fabric.js canvas
body: <p>I am trying to manipulat an svg file  with fabric.js. I am loading the svg string <code>fabric.loadSVGFromString</code> into the canvas correctly. My question is how can I manipulate some parts of the svg. </p>
  
  <p>For example, I imported an electronic breadbord with lot of holes as shown in the pic below <a href="https://i.stack.imgur.com/cI7FW.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/cI7FW.png" alt="electronic board"></a>. </p>
  
  <p>How could I detect if a hole has been clicked? How could I get the clicked part?</p>
  
  <p>Thank you </p>
