title: How do you reflow Highslide so that it stays centered?
body: <p>I am building a site which has logic to check whether things are expanded, collapsed, added, deleted, etc and when that happens, we get the Highslide expander and call the reflow function.  Something like:</p>
  
  <pre><code>//Open Popup
  top.hs.htmlExpand(null, {objectType:'iframe',src:url,align:'center'});
  
  $(document).ready(function(){
    //start jquery function
      reflowPopup();
    //end jquery function
  });
  
  function reflowPopup() {
    if (top.hs != undefined) {
      var expander = top.hs.getExpander();
      if (expander) {
        expander.reflow();
      }
    }
  }
  </code></pre>
  
  <p>This works great, however it centers vertically/horizontally on load, but when reflowed it leaves the top where it initially loaded and expands/collapses the bottom as it is reflowed.  I would like it to be reflowed equally.  So if it is to expand 20px, move up half to stay vertically centered.  What would be the best way to do this?  </p>
