Oh man, I\'ve been tearing my hair out over this. 4 hours on a dropdown.

I\'m using Twitter Bootstrap.

The fixed nav at the top has a dropdown, pretty standard s

    You can also add propagate click event from the parent page with this code (fixed the same issue for me):

    var myFrameContents = document.getElementById("frame").contentWindow.document;
myFrameContents.body.addEventListener("click", function() {
    document.body.click();
});

    This is the full solution I implemented based on merv's great answer. If there is a better way for me to post the solution for those coming in the future please let me know.

    This jquery was added to the bottom of the html of the pages in the frame:

    $('html').on('click', function () {
  parent.$('#frame').trigger('click');
});

    The dropdown was switched to a button and restyled to fit into the navbar. In the html:

                    <li class="btn-group" id="samplebtn">
                    <a href="#" class="btn btn-primary dropdown-toggle" role="button" data-toggle="dropdown">
                        <i class="icon-pencil icon-white"></i>
                        Sample
                        <b class="caret"></b>
                    </a>

    In the CSS:

            #samplebtn {
        position:absolute;
        top: 0;
        margin: 0px;
        padding: 0px;
        border: 0px;
        }
        #samplebtn .btn {
            border: 0px;
        }

    full code of solution (update of the full code in the question - this is the outside frame only):

    <!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8">
        <title>test</title>

                left: 0px;
                position: absolute;
                top: 50px;
                width: 100%;
            }

    Fixed testing site you can preview at (but don't copy the whole page code, as it has some server side (cloudflare) stuff in it). http://www.joshlevent.com/dropdownbug/
