It may be possible to do this using a select field plus dynamic options. The cummeRbund tool seems to use a select that uses arbitrary Python to generate options - but I may be missing something. https://github.com/galaxyproject/tools-devteam/tree/master/tools/cummeRbund If it really does that - than it would seem to be possible to ping a remote URL as part of that option building. Hope this helps, -John On Sun, Feb 8, 2015 at 8:52 AM, Langhorst, Brad <Langhorst@neb.com> wrote:

Hi:

I need users to specify a project when they run a tool… I would like this to be a select list whose set of options comes from a remote url.

What’s the best way to achieve that UI?

Should I try to add a from_url attribute to the options tag?

Thanks,
