Hi Katherine,

This all happens in javascript these days, and it's unfortunately a little harder to track down all the moving parts than it used to be when this was all rendered serverside.  The client requests tool information (like which parameters are necessary, etc) from the API, which it then renders using the primary tool form found here:

This extends the form code found here:

And individual element types (a select box, for example) can be found here:

Does this help?

Sorry, I know relatively little about how Galaxy loads the tool XML

the codebase with grep at the command line (also searching
directly on GitHub works pretty well) trying to trace functionality
when I was debugging something.

Hopefully one of the Galaxy developers will be able to answer.
