I don't understand why this simple example is not working. I can't find the error. I am using bootstrap 2.3.2 and jquery 1.9.1 source files. Thanks in advance for your help. See the code below. The dropdown part is from the bootstrap site (http://getbootstrap.com/2.3.2/components.html#dropdowns).

You do not have a button that will trigger drop down to appear. Replace <!-- Link or button to toggle dropdown --> with the following:
<button class="btn dropdown-toggle" data-toggle="dropdown">
Action
<span class="caret"></span>
</button>
