title: Does hideNoSelectionOption attribute work for Primefaces?
body: <p>I have been following this link to achieve hiding of typical default 'select..' item of Primefaces dropdown after selecting another item:</p>
  
  <p><a href="https://stackoverflow.com/questions/11360030/best-way-to-add-a-nothing-selected-option-to-a-selectonemenu-in-jsf">Best way to add a &quot;nothing selected&quot; option to a selectOneMenu in JSF</a></p>
  
  <p>This is not working for Primefaces.</p>
  
  <p>Since the attribute <code>hideNoSelectionOption</code> is also not mentioned in Primefaces Showcase documentation, I doubt if this works for Primefaces.</p>
  
  <p>Does anybody know an alternative for this in Primefaces?
  I am using Primefaces version 5.3.</p>
