JSPX drop down list

I am writing a oracle ADF fusion web app using jdeveloper 11.1.2.0.0. In a jspx page I have a drop down list which is populated by a menu model. I want it to be shown expanded when the page loads in the browser. Please give me an idea.

Thanks Sameera

it is true that there is no direct or programmatic way to emulate the triggering of click event on a dropdown to open it, but you can do this by the following code. What you need are:

  1. jquery-1.7.1.min.js
  2. ExpandSelect.js

The bean who supplies the List of SelectItem is:

import java.util.ArrayList;
import java.util.List;

import javax.faces.model.SelectItem;

public class BackBean {
    private List<SelectItem> options;

    public BackBean() {
        options = new ArrayList<SelectItem>(0);
        options.add(new SelectItem("Option 1", "Option 1"));
        options.add(new SelectItem("Option 2", "Option 2"));
        options.add(new SelectItem("Option 3", "Option 3"));
        options.add(new SelectItem("Option 4", "Option 4"));
        options.add(new SelectItem("Option 5", "Option 5"));
    }

    public void setOptions(List<SelectItem> options) {
        this.options = options;
    }

    public List<SelectItem> getOptions() {
        return options;
    }
}

And the jspx page is:

<?xml version='1.0' encoding='UTF-8'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1" xmlns:f="http://java.sun.com/jsf/core"
          xmlns:af="http://xmlns.oracle.com/adf/faces/rich">
    <jsp:directive.page contentType="text/html;charset=UTF-8"/>
    <f:view>
        <af:document title="Home" id="d1">
            <af:form id="f1">
                <af:resource type="javascript" source="/js/jquery-1.7.1.min.js"/>
                <af:resource type="javascript" source="/js/ExpandSelect.js"/>
                <af:panelStretchLayout id="psl1">
                    <f:facet name="center">
                        <af:selectOneChoice label="Menu" id="soc1" clientComponent="true" styleClass="menu">
                            <f:selectItems value="#{backingBeanScope.backBean.options}" id="si1"/>
                        </af:selectOneChoice>
                    </f:facet>
                </af:panelStretchLayout>
            </af:form>            
            <af:resource type="javascript">
                $(document).ready(function(){                    
                    ExpandSelect(document.getElementById($($('.menu > tbody > tr > td').next().find('select')).attr('id')));
                });
            </af:resource>            
        </af:document>
    </f:view>
</jsp:root>

Here is the screenshot I have: enter image description here

Hope this will help. Let me know your feedback.

There is no programmatic(meaning javascript) way of triggering the disclosure of a native dropdown element. As advised by others, consider using a different UI strategy. Maybe an af:table that is selectable?

Consider using another type of component instead of a drop down. For example how about just using an iterator to show the list of options?
