title: populate a select dropdown on the basis of other other select dropdown
body: <p>How would I populate a select dropdown whose values are dependent on what is selected in the parent dropdown. E-g, First dropdown has country names in it, and on selection the next dropdown would load the corresponding states of that country, selected in first dropdown. And then say I have a third dropdown, where I am putting the image of that particular state, that corresponds to what is selected in second dropdown.</p>
  
  <p>How can this be done in JQuery. </p>
  
  <p>E-g </p>
  
  <p>Country>>>>> States>>>>>>Map of This State</p>
