Combobox Tag (Form Tag) Example

                         

In this section, we are going to describe the combobox tag. The combo box is basically an HTML INPUT of type text and HTML SELECT grouped together to give you a combo box functionality. You can place text in the INPUT control by using the SELECT control or type it in directly in the text field.

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

<action name="comboboxTag" class="net.roseindia.comboboxTag">
       <result>/pages/uiTags/comboboxTag.jsp</result>
</action>

Create a list in the action class and populate it with various items as shown in the  " comboboxTag" class.

 comboboxTag.java

package net.roseindia;
i mport com.opensymphony.xwork2.ActionSupport;
import java.util.*;

public class comboboxTag extends ActionSupport{
  
  private List fruits;
  public String execute()throws Exception{
    fruits = new ArrayList();
    fruits.add("Apple");
    fruits.add("Mango");
    fruits.add("Orange");
    fruits.add("Pine Apple");
    return SUCCESS;

  }

  public List getFruits(){
    return fruits;
  }
}

Create a jsp using the tags <s:combobox>

The tag  <s:combobox label="Colors Name" name="colorNames" headerValue="--- Please Select ---"  headerKey="1" list="{'Black','Green','White','Yellow','Red','Pink'}" />  prints a combobox with name color Name and an HTML INPUT of type text and HTML SELECT grouped together created using the list.

The tag <s:checkboxlist name="Animals-name" list="animals" /> prints a combobox with name Fruits Name and an HTML INPUT of type text and HTML SELECT grouped together created using the "fruits" list of the action class "checkboxlistTag".

 comboboxTag.jsp

<%taglib prefix="s" uri="/struts-tags" %>

<html>
  <head> 
    <title>Combobox  (Form TagTag Example!</title>
      <link href="<s:url value="/css/main.css"/>" rel="stylesheet"
          type="text/css"/>
  </head>
  <body>
  <h1><span style="background-color: #FFFFcc">Combobox 
                 Tag Example!</span></h1>

  <s:form>
    <s:combobox label="Colors Name" name="colorNames" 
        
headerValue="--- Please Select ---"
    headerKey="1" list="{'Black','Green','White','Yellow',
                  'Red','Pink'}" 
/><br>
    
    <!-- Use array list --><br>
    <s:combobox label="Fruits Name" name="fruitsNames"
          
headerValue="--- Please Select ---"
    headerKey="1" list="fruits" />

  </s:form>
  </body>
</html>

Output of the comboboxTag.jsp:
