title: Filtering spcific with checkboxes
body: <p>My question is that I want a filtering system that will filter by checked checkboxes. 
  The tool is to my comparison website where I compare TV packages.</p>
  
  <ol>
  <li>my visitors should filter the packages by the tv-channels they want to se.</li>
  </ol>
  
  <p>example;<br>
  Checkbox 1: Discovery<br>
  Checkbox 2: Animal PLanet<br>
  Checkbox 3: Disney Channel</p>
  
  <p>Output should be the matching TV-package<br>
  Package 1: (contains Discovery and Disney channel)<br>
  Package 2: (contains Animal Planet, Disney channel)<br>
  Package 3: (contains Animal Planet)</p>
  
  <p>So if checkbox 1 is checked it should only show package 1.<br>
  if checkbox 1 + checkbox 2 is checked it should say "No match found, but this package was was closest to your choice"<br>
  if checkbox 2 + checkbox 3 is checked it should only show package 2 which match the visitors choice exactly.</p>
  
  <p>I hope your can help me out. I have been searching a lot after this specific solution without any success. </p>
