    <option value="TE">tight end</option>
    <option value="K">kicker</option>
    <option value="DST">defense / special teams</option>
  </select>
</div>

<script lang="application/javascript">
  // wire up dropdown controls
  $(document).ready(function(){
    if ($.fn.Dropdown){
      $('.ms-Dropdown').Dropdown();
    }
  });
</script>

I've been wrestling with this too - So far, the best option I can figure using jQuery (could easily be modified to used vanilla Javascript) is to simulate a click on the new Fabric item:

for example:

        var methodDropdown = document.getElementById("fabric_name_builder_method");
        g_fabricDropdownMethod = new fabric['Dropdown'](methodDropdown);

       // Fabric component trickles down the change event to the original control
        $("#native_name_builder_method").change(onChange_Method);
        
        // This seems to work - kind of hackish....  Obviously, you wouldn't hardcode the dropdown item index.
        $(g_fabricDropdownMethod._dropdownItems[5].newItem).click();

Being a complete untrained hack, I tried the brute-force method of looking through the dom and found that there is a Title element that gets updated with the value of the selected item (at least in all of the 20 times I tested it). To get that, I just navigated the dom to find that element and grabbed the html. I'm sure it is not proper but it worked for me.

Here's a snip of the html and function I built:

            <div id="selectAProp" class="ms-Dropdown" tabindex="0">
                <label class="ms-Label">Select a property</label>
                <i class="ms-Dropdown-caretDown ms-Icon ms-Icon--ChevronDown"></i>
                <select onchange="changeProps()" class="ms-Dropdown-select">
                    <option>Choose a option&amp;hellip;</option>
                    <option>setShowInNewForm</option>
                    <option>setShowInEditForm</option>
                    <option>setShowInDisplayForm</option>
                    <option>Description</option>
                </select>
            </div>

<script type="text/javascript"> function changeProps() { var selectAProp = document.getElementById("selectAProp").lastElementChild.innerHTML; // Now you just do whatever you needed with the selected value. } </script>
