Dear Experts,

I want to create dynamic-dropdown menu in Struts.

Say, I have Department, Teams and Members.

I need to populate Teams based on the Department selection and Members based on the Teams selection.  At first thought, I was about to post in JavaScript section. But, just want to know if anyone has accomplished similar task in Struts.

<TR>

<TD><bean:message key="FilterList.department"/></TD>
<TD colspan="3" >
<html:select property="department" onchange="deptSelected();" >
<html:option value="Department A"> Department A </html:option>
<html:option value="Department B"> Department B </html:option>
</html:select>
</TD>

</TR>

<TR>

<TD valign="top" ><bean:message key="FilterList.teams"/></TD>
<TD>
<html:select multiple="true" property="teams" onchange="teamSelected();">
</html:select>
</TD>

<TD valign="top" ><bean:message key="FilterList.members"/></TD>
<TD>
<html:select multiple="true" property="members">
</html:select>
</TD>

</TR>

Please share me if you have any suggestions.

Thanks.

You can do a separate request to the database for each option selected. All you can load everything up at once, put them in a JavaScript array and dynamically change the values. Up to you, it's not really a Struts issue.

It's a framework for handling that kind of things. Supports dynamic combos and the such.

Might help you.
