title: Angular p-dropdown create options dynamically from one options array
body: <p>I am trying to create multiple dropdowns in Angular and need every drop down to display one less option. I got this far but now my dropdown always initializes with a value.
  I have multiple dropdown and try to use one single options array and generate my data based on these options. I also dont know beforehand how many dropdown I will need.
  The issue is that I also need a blank value the user sometimes does not want to select value.</p>
