title: load options of a select box dynamically based on value of another select box in react
body: <p>I m trying to create 2 select boxes in which options of 1st select box are fixed but the second ones change based on the selected value of first div.</p>
  
  <p>eg:
  1st Select:</p>
  
  <pre><code>&lt;select&gt;
      &lt;option&gt;Integers&lt;/option&gt;
      &lt;option&gt;Alphabets&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>Then if Integers is selected in 1st select then I want integers 1 to 10 as options in the 2nd select box. But if Alphabets is selected the a to z should come in options of the second select box.</p>
