Hi,

I intend to have a view that has 3 boxes with the following
features

  1. One selection change in 1st select box, the second select box has to
    get updated.

  2. On selection of 2nd select box, the 3rd select box has to be updated

  3. I tried using select_tag and observe_field as mentioned in
    http://brentrubyrails.blogspot.com/2008/02/how-to-dynamically-update-contents-of.html
    but the problem is that with select_tag I cannot configure the
    to be fixed select box. ( I want a fixed select box of size 3)

  4. Also my observe field does not work in this case don’t know for what
    reason.

  5. Also is there any other easy way to get this implemented

ALl I need is to display this

Class A has Methods A1,B1,C1 and when A1 is clicked I need to display
A1’s parameters …

All this information is stoed in Database and I need to pick these and
display

Regards,
Sudhi
