Hey guys!
I was wondering. I''m generating a select box in my view where the user
can pick from a number of alternatives. However, I would like the last
option to be "Add new..." and then a box would pop up allowing the
user to enter a new value.
Now I''ve got all the JavaScript and the Rails code to allow the user
to enter a new option, the problem is how do I add the last
alternative ("Add new...") to my select box?
Take care!
Alex
