How to fix the second select box (Select Subsystem) that it wouldn't have the first option selected? Currently it will select automatically: xroad-center.... when opening the dropdown. It will also result that if I want to know information about the first option which is already selected xroad-center , I have to select some other option first and then re-select the xroad-center .

Answer 1

I found that after the first selection on the second box, the header option :

<option selected>- Select subsystem: -</option> disappears.

Do some test : remove it and see what happens. If it solve the problem, try may be to instead include it in your second ajax function : subsystem_select(val)
