Yes download the jQuery and you can simpley do with jQuery/Ajax.

<select onChange="$('#formDiv').load(this.options[this.selectedIndex].value)">
  <option value="/pages/form1.html">form1</option>
  <option value="/pages/form2.html">form2</option>
</select>

<div id="formDiv"></div>

This is basic structure I gave, You can enhance it to work it in more secure way.
