</html>When I click on an element f.ex. the triangle it is added to the canvas. When I click on the added triangle a menu on the right should go up. However, the element does not get selected.
Any suggestions what I am doing wrong?
I appreciate your replies!
Solution
you have second canvas element next to your canvas, it prevents from clicking on first canvas element, removing this second canvas solves this issue
