Hi!

You can call a JavaScript function in "onChange" event. This function retrieves the selected value and call any action you want:

<html:select name="YouForm" property="demoProp" styleClass="list-menu" onchange="functionSubmit(this)" >
   //html:select code goes here
</html:select>

And the javaScript function

function functionSubmit(sel){
                var value = sel.options[sel.selectedIndex].value;
                window.location = '/<%=application.getServletContextName()%>/app/action.do?requestParam='   + value; 

}

Havent tested but it's an idea.

bye!

Are you using a library like jQuery or Prototype? If so, you can set a click handler to call a JS function, which in turn makes an ajax request to the .do action.
