Struts2 - Optiontransferselect Tag (Form Tags)

In this section, we are going to describe the Optiontransferselect tag. The Optiontransferselect tag is a UI tag that creates an option transfer select component. There are two <select ...> tags with buttons in the middle of them, which allows options in each of the <select ...> to be moved between them. It auto-selects all its elements upon its containing form submission.

NOTE: The id and doubleId parameters are not needed to supply as they will get generated when the optiontransferselect tag is being used in a form tag. The generated id and doubleId will be <form_id>_<optiontransferselect_doubleName> and <form_id>_<optiontransferselect_doubleName> respectively.

Add the following code snippet into the struts.xml file.

struts.xml
<action name="optiontransferselectTag">
  <result>/pages/uiTags/optiontransferselectTag.jsp</result>
</action>
