selecting an option - how to?

I have the code below:

<td width="100%" class="tableinfo">
    <select name="zonas_codigo" size="1" class="formulario">
            <logic:iterate id="listaZonas" name="listaZonas"
scope="request">
               <option value="<bean:write name="listaZonas"
property="codigo"/>"><bean:write name="listaZonas"
property="nombre"/></option>
          </logic:iterate>
    </select>
   </td>


I want to select (with SELECTED html label) an option making a comparison
with the option code saved in the request.

How can i do that? Must I use bean:write bundle property ?? I can't find any
reference about my problem in the documentation. Thanks

Dani,

I've not tried to select a single option like this, but I did select 
multiple options from a multi-select box using the struts form tags:

<html:form ...>
<bean:define id="options" name="myForm" property="options" 
type="java.util.Collection" />
                <html:select
                    multiple="true"
                    property="selectedOptions"
                    size="15"
                >
                    <html:options collection="options" property="id" 
labelProperty="name"/>
                </html:select>
</html:form>
In my ActionForm, I built up a List of options with getId() and 
getName() methods. Then I built an Integer[] of selectedOptions that 
correspond to the getId() method on each option. I'm sure you could do 
the same thing w/ an Integer[] of length 1. Just remove the 
multiple="true" and size="15" from the <html:select> tag and you should 
be good to go.

There's probably a better way, but this should work.

Not sure exactly what you are talking about but if you want to
have option values and labels you can use the struts

<html:options> using the "property" and the "labelProperty" parameters.
where property corresponds to the option value and labelProperty
corresponds to what is displayed.

hth,
brian
