Hi
I want to make a clickable dropdown menu but I find some problems

function setup() {
  textAlign(CENTER);
  //background(200);

  sel = createSelect();

  sel.position(11.5, 12 );
  sel.size(39, 39)

 sel.option('A');
  sel.option('Nom');
  sel.option('Pénom');
 sel.option('Société');
 
sel.changed(mySelectEvent);
}

function mySelectEvent() {
 createA('http://p5js.org/', 'this is a link');
  }
