$(document).ready(function () {
  $('.group').hide();
  $('#option1').show();
  $('#outer').change(function () {
    $('.group').hide();
    $('#'+$(this).val()).show();
  })
});

#option1{
  background-color:red;
  height:400px;
  color:white;
}

#option2{
  background-color:blue;
    height:400px;
  color:white;
}

#option3{
  background-color:green;
    height:400px;
  color:white;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<select id="outer">
  <option value="option1">option1</option>
  <option value="option2">option2</option>
  <option value="option3">option3</option>
</select>

<div id="option1" class="group">Red</div>
<div id="option2" class="group">Blue</div>
<div id="option3" class="group">Green</div>
