You have two options:
1. Look at the javascript to see what interfaces it uses. If it is
generating menues, then it is getting the data it uses to generate
those menus from somewhere. Once you have found that resource,
you can access it yourself with a request from your Python code.
This is generally the best approach if possible.
2. You can automate a bowser thorough a COM/XPCOM/etc. interface
which allows you to access the DOM object in real time as it is
modified by the Javascript and even to trigger javascript events.
There are libraries that will do this as well. I have used
this on heavy AJAX style interfaces with mountains of spagetti
Javascript that were simply too large and poorly designed to
try to understand.
