Drop down not working

Hi,

I created a form in the following url: http://elchongmotor.com/loan-application/.

I have a issue with dropdown. The dropdown works fine when the user fill in the form. If the required drop down is not filled, as usual there will be a prompt under every required field. At that time the dropdown will be unclickable. It only happens if i use “select*” and not with “select”.

Any advice on how can i fix this issue?

Thank you.
