Hi Guys,

Can anyone recommend a way to have a drop down menu that show a list of  
directories?

In my controller I have:  
@files = [Dir.glob(’/mydirectoryofcoolfiles/\*’)]

Then the form I am unsure of how to do it:  
\<%= f.collection\_select :job\_id, @files, :id, :job\_title, :prompt =\>  
“Select a shot” %\>

The app has a directory with lots of ‘job’ directories in it.  
Each job folder has a number of ‘asset’ folders in it.

I want the user to select a ‘job’ in a dropdown menu, and then a second  
menu lists the folders in that particular folder

any ideas?

Thanks

Adam
