title: Magento list products with selected options from multiselect
body: <p>In my module I have to get list of all products with selected options from multiselect...</p>
  
  <p>Does anyone have collection query or example for this?</p>
  
  <p>My code:</p>
  
  <pre><code>$collection = Mage::getModel('catalog/product')-&gt;getCollection()
              -&gt;addAttributeToSelect('*');
          $collection-&gt;addAttributeToFilter('frustration_flags'); // multiple select attribute
          $collection-&gt;addFieldToFilter(array(array('attribute'=&gt;'frustration_flags','finset'=&gt;array('FFL, FTG'))));
  </code></pre>
