title: Chaining yadcf multi_select filters together
body: <p>Is there a way to chain filters together where by filters applied in one column will pre-filter the available filters in other columns?  Primarily I'm interested in this from a multi_select standpoint, but it could be universal to all filters types I guess.</p>
  
  <p>For example:</p>
  
  <p>Column 1's data contains:</p>
  
  <ol>
  <li>Oklahoma</li>
  <li>Missouri</li>
  <li>Utah</li>
  <li>Texas</li>
  <li>Kansas</li>
  </ol>
  
  <p>Column 2's data contains:</p>
  
  <ol>
  <li>Obama</li>
  <li>Romney</li>
  </ol>
  
  <p>From the dataset I know that all Column 1 data that has 'Oklahoma' will always mean that Column 2 will equal 'Romney'.  Thus, if I select 'Oklahoma' from a mutli_select, then the drop down for the multi_select for Column 2 should now only show 'Romney'.</p>
  
  <p>Basically, can I pre-filter my filters based on other filters already put in place?</p>
