Thanks a lot for your help, I have a last small question To not have to call the server when the user select an new entry*in the first combo-box I have to add JavaScript code as indicated in your preceding mails
but I must also place the collections in the HttpSession or Servlet Context (if the collection is the same for all clients) and not in the request. Is it true ?

Sandra, This works with the javascript code Chris pointed you to. The communityIssue is the parent field and there are two dependent fields (targetAudience & activityType). - Eric <td> <html:select property="communityIssue" styleClass="select" size="10" multiple="true" tabindex="11" onchange="fillSelectFromArray(this.form.communityIssue, this.form.targetAudience, ((this.selectedIndex == -1) ? null : audiences)); fillSelectFromArray(this.form.communityIssue, this.form.activityType, ((this.selectedIndex == -1) ? null : activities));"> <html:options collection="communityIssueList" property="value" labelProperty="label"/> </html:select> </td> Here is the javascript and STRUTS code to write the array into the page: <script language="javascript"> audiences = new Array( <bean:write name="targetAudienceJSArray" filter="false"/> ); activities = new Array( <bean:write name="activityTypesJSArray" filter="false"/> ); </script> ----- Original Message ----- From: "Heligon Sandra" <[EMAIL PROTECTED]> To: "'Struts Users Mailing List'" <[EMAIL PROTECTED]> Sent: Thursday, January 30, 2003 8:41 AM Subject: RE: how to use two combo-box which depend one on the other ? > Do you have an example of this with the struts tags > that allows to display combo-box from a collection of JavaBeans > <html:select ...> > <html:option > </html:option> > > Sandra > > -----Original Message----- > From: Chris Halverson [mailto:[EMAIL PROTECTED]] > Sent: 30 January 2003 17:29 > To: Struts Users Mailing List > Subject: Re: how to use two combo-box which depend one on the other ? > > > Heligon Sandra <[EMAIL PROTECTED]> writes: > > > Do I have to ask the web server each time the user select a new > > function, or is it possible to do this logic on the client side > > (with JavaScript probably ???). > > Yep, w/ JavaScript.
