title: How to handle elm mdl indexes in a big single page application?
body: <p>This is an example from elm-mdl</p>
  
  
  
  <pre class="lang-elm prettyprint-override"><code>Button.render Mdl [0] model.mdl
    [ Button.raised
    , Button.ripple
    , Button.onClick PollMsg
    ]
    [ text "Fetch new"]
  </code></pre>
  
  <p>Index here is [0]. I assume if I am building a single page application I can put indexes like ["page0", 0]. Is that right?</p>
  
  <p>But does that mean that all the mdl data for all the buttons in the application is in memory? How is it working?</p>
