title: Is is possible to have Selectize not dropdown until there are 3 chars entered?
body: <p>I am using <code>Selectize</code> to search a large set of data that I have in an array locally.</p>
  
  <p>When the user clicks on the Selectize element, it opens right then and tries to show the full list.  This is some <code>3000</code> items that have to go through my custom render right then.</p>
  
  <p>I would rather that the user has to enter at least 3 chars then show what matches.</p>
  
  <p>I know that there is a <code>"maxOptions"</code> setting, but that still shows the dropdown when the user clicks in.  Which is confusing to them, because now I am showing only <code>100</code> of the <code>3000</code> options.</p>
  
  <p>If possible, I would also like it to not show the dropdown once an option has been selected (this is for <code>maxItems = 1</code>).</p>
  
  <p>Note: I tried to use <code>openOnFocus=false</code> to try to do this, but it seems to only stop the first click from opening the dropdown.</p>
  
  <p><strong>Any ideas on how I can keep Selectize from opening unless the user is typing in a search?</strong></p>
