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