title: Changing the style of each feature in a Leaflet GeoJSON layer
body: <p>I have been studying the <a href="http://leafletjs.com/examples/choropleth.html" rel="noreferrer">Leaflet Chloropleth example</a>.</p>
  
  <p>In my Leaflet application, I have a jQuery dropdown that, when selected, fires a function that takes the name of a state as an argument. I want to use that state name to update the Chloropleth map.</p>
  
  <p>What is the pattern for changing the style of a Leaflet GeoJSON layer? Should I recreate the layer I created with <code>L.geoJson()</code> a second time? It seems as though the layers are drawing on top of each other with that approach.</p>
  
  <p>I can provide a Fiddle if needed.</p>
