title: jspdf convert html to pdf with multiple pages
body: <p>I'm using jsPdf and html2pdf to convert html to a pdf file.</p>
  
  <p>I can convert the html fine and download the file but if the html is too big to fit onto a single page, it does not create the other page(s), how do I do this?</p>
  
  <p>code is:</p>
  
  <pre><code> var pdf = new jsPDF('l', 'pt', 'a4');
   pdf.canvas.height = 72 * 11;
   pdf.canvas.width = 72 * 8.5;
   html2pdf(document.getElementById(id), pdf, function(pdf){
       pdf.save('file.pdf');
   });
  </code></pre>
