Question on custom javascript

[Gregor Melhorn <g....@web.de>]

Hello tapestry users,

 

I'm rather new to tapestry, so forgive if I might ask some "dumb" questions
:-)

 

I want to create a component that allows me to include a dhtml menu on my
site, with the main level always visible as a table and the sublevels
created by javascript, so users without javascript enabled can access the
deeper layers of the site as well, but will have to click more often. The
menu should be different for the security roles on my site, with
administrators, mods, and several other user roles getting different menus
to see.

 

I thought of using the java dhtml menu script from smartmenus.org, since it
seams pretty mature to me und supports nearly every browser one could think
of.

 

The scripts consists of several .js-files, wich are dynamically loaded
depending on browser type. One of these files includes the menu
specification (styles, menu items, etc.). That's the file I would have to
generate with tapestry. 

 

But how do I do it? 

 

I suppose it should be possible to do it by implementing the .js-file with
menu information as an ordinary page, but this seems kind of wasting
resources to me, or doesn't it? Or do I have to implement some kind of
engine service?

 

And where do I put the check for the user roles? Should I implement
different components for each user type?

 

I don't want to go into the wrong direction from the start, so maybe someone
could give me some hints on how this is best implemented.

 

I'm using Tapestry 3.0.

 

Best regard

You may want to use Krysalis's Menu component:

implement PageRenderListener and override pageBeginRender().

> Should I implement different components for each user type?

Yes if the user types are much different. Otherwuse just 
use some Conditional components.

For starters, try the Tapestry in Action book, chapter 10 and Appendix D.
Or the third entry in the FAQ page at
