title: Ng-Grid Multiple Filtering in Column
body: <p>Let's say I had one of many columns of data in an ng-grid like so:</p>
  
  <h2>Status</h2>
  
  <p>Open</p>
  
  <p>Closed</p>
  
  <p>Open</p>
  
  <p>Closed</p>
  
  <p>Pending</p>
  
  <p>Pending</p>
  
  <p>Closed</p>
  
  <p>I can filter for just one, but can I have multiple filters using ng-grid? For example, filtering for 'Open' gives me back all the ones that are 'Open', but what if I wanted to get back both 'Open' and 'Closed'? So the result would be like:</p>
  
  <h2>Status</h2>
  
  <p>Open </p>
  
  <p>Closed</p>
  
  <p>Open</p>
  
  <p>Closed</p>
  
  <p>Closed</p>
  
  <p>Thanks for any help!</p>
