I have a form controller.Form element is a drop down box.

For eg there is user name form element.if user select his name .I want the children names to be loaded for particular user.

I have List<Children> getChildernByUser(User user);

<form:select path="user.username" cssClass="text medium">
<c:forEach items="${users}" var="user">
<form:option value="${user.username}" label="${user}"/>
</c:forEach>
</form:select>

Please would like to know how this can be made using jquery or ajax.If user is selected in next form element he gets all his children to select .
