Hi Lakshman,

the following code can help you do what you want :

<hbj:dropdownListBox id="calendar" tooltip="Calendar" selection="<%= selected %>">
<%
String[] weeks = myObjectBean.getWeeks();
for (int i = 0; i < weeks.length; i++) {
%>
	<hbj:listBoxItem key="<%= i %>" value="<%= weeks<i> %>"/>
<%
}
%>
</hbj: dropdownListBox>

The <%= selected %> snippet allows you to pre-select one of the options (provided that the variable 'selected' is equal to one of the listBoxItem keys).

You can also add onSelect to the tag (e.g. = "setSelectedItem"). It corresponds to a method in the corresponding JSPDynPage class. This means that when you select another item in the dropdown list, the method in your Java class is performed (allowing you to save the selected value and performing actions with it)

I hope this helped you enough,

kind regards,

Frederic
