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.
