How to Enable

In order to have pdf preview on your question page, following has to be added through customization in your main.js file.

$(document).ready(function(){
  $('a[href$=".pdf"]').each(function(index, el){
    $(this).replaceWith('<iframe src="' + $(this).attr("href") + '" width="100%" height="700"></iframe>');
  });
});

Save the file and now you should see PDF Previews in your Knowledge Base.
