I would know if it’s possible to do the following:

I have a head-DIV, main-Div and a navigation-DIV and a  
global application Layout.

* * *

- 

```
 head -

```

- link1 link2 link3 -

* * *

* * *

* * *

- nav - main -

* * *

* * *

* * *

* * *

When I click a link in the head-DIV (link\_to) I load  
the according rhtml-File within the controller -\> the main-DIV  
is updated showing the requested content.

How can I update the nav-DIV to present a submenu to the user?  
Must I call a render calling a rjs file with replace\_html or is  
there a more recommended way to do this?

Thanx

That would be the best idea IMO. I had to do the same you need and i  
tried some solutions, the best one to keep clean code and performance  
is the rjs with the replace\_html.

Could you give me a code-example please?

controller:

def index  
end

template:  
index.rhtml (rendered in the main-DIV)

Where must I put the rjs code that the navigation gets updated when  
the index.rhtml is rendered?

Thanx
