Do you have some code to show how you are doing this? Steven -----Original Message----- From: O'Reilly John [mailto:[EMAIL PROTECTED]] Sent: Friday, July 20, 2001 6:54 AM To: '[EMAIL PROTECTED]' Subject: RE: Tree We are using Cocoon for our presentation (using XML/XSP/XSL). What we have done is to store menus in static XML files. In response to a request an action (making use of a menu manager) can load a specific menu. If the action originated from selecting a menu option then that option is modifed by setting the "selected" attribute to true. If the option has a sub menu then we set "expanded" to true. The XSL can then interpret these attributes (i.e. not associating a href with an option if selected=true and showing the sub menu in expanded=true) to display the menu tree. Has anyone else had experience of using menus with Struts/Cocoon. Is there a better way of doing the above? -John > -----Original Message----- > From: Matt Raible [SMTP:[EMAIL PROTECTED]] > Sent: 19 July 2001 19:56 > To: [EMAIL PROTECTED] > Subject: Re: Tree > > Have you seen the "struts-menu" application - it uses struts, > javascript, and xml to build a DHTML tree. > > Can be found at: > > http://husted.com/about/struts/resources.htm#extensions > > Matt > > > --- Levi Cook <[EMAIL PROTECTED]> wrote: > > I agree with Matts points, in addition here are a couple more > > thoughts > on > > the challenge of tree navigation-- > > > > 1) From a mvc design perspective, a tree is just a view; assigning > > responsibility of rendering a tree to "a lot of action classes" is > probably > > not optimal. > > > > 2) Offhand, a key to building an effective tree view rests with > > thinking about recursive associations-- ie. a container class that > > may contain > itself > > (self containment) > > > > Here's a common example: > > > > ---------- > > | Folder |<>-- 1 > > ---------- | > > | * | > > | | > > ---------- > > > > In this case, a Folder can have zero or more subfolders-- thus > > yielding > a > > hierarchy, or tree :) Each folder can be contained by exactly one > folder. > > > > With this model in mind, I believe you should consider creating a > > custom > tag > > that expects this *type* of structure.
