Help with ajax call with date_select

Rails
1

I have an ajax call (when a check box is checked) to toggle the day
field of
date_select helper, and it works fine.

What I want to do is start the page with the day hidden, but if I do
something like :discard_day => true, the ajax call doesn’t work

Thank you,
Rodrigo

discard_day property takes hidden field instead of hide the day select
dropdown
So instead use discard property, you have to do hide by default on load
by javascript or by css
