Multiple Select Option JSP

This section describes how to use multiple select option in JSP.

In a form sometimes you will be required to select the various options that you have to displayed them or manipulate with that value. This facility can be provided by the <select> tag of HTML that makes the drop down list with number of options. Values in a drop down list is inserted using the <option> sub tag of <select>. Let's come to our discussion how to display the values of the items selected in drop down list. Follow the example :

In the following example we will describe how to fetch the value of items selected in the drop down list. In this example at first I have created a JSP page named jspMultipleSelectOption.jsp where designed a form onto which taken a <select> tag and then put the value using its subtag <option>. If you want a default value setting you can use the attribute selected of <option> attribute. And taken a submit button for submitting the form. Then write the java codes, using the scriptlets to fetch the selected values from the drop down list and simply displayed them.

jspMultipleSelectOption.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>

<option>Brown</option>
<option>Gray</option>
</select>
<p><input type="submit" value="submit"></p>
</form>

<% 
String clrs[] = request.getParameterValues("color");
if(clrs != null)
{
%>
<p><b>You have selected the following colors</b></p>
<ul>
<%
for(int i=0; i<clrs.length; i++)
{
%>
<li><%=clrs[i]%></li>
