thank help.

you need preset inputs request parameter values. can access parameter values in el ${param.name}. in case of dropdowns rendered html <select> element, need set selected attribute of html <option> element in question. can make use of ternary operator in el print selected attribute whenever option value matches request parameter value.

basic example:

<select name="foo">    <c:foreach items="${options}" var="option">        <option ${param.foo == option ? 'selected' : ''}>${option}</option>    </c:foreach> </select>
