title: How to display iframe content without scrolling in wordpress
body: <p>I'm creating a website. I have a sidemenu bar and its menu list is from page and post of my wordpress blog. Now, everytime I select one of the menus, its content will display in one of my created templates and it will display in an Iframe.</p>
  
  <p>The content of my created template have 'div' which has class of "collapse".
  Everytime I trigger the collapse div, the content does not show completely unless I scroll it.</p>
  
  <p>I want it to display without scrolling and increase the height of Iframe depending the size of my collapsible div.</p>
