Does anyone know of a RoR implementation of a TreeView in which you can  
navigate to leafs of branches and select multiple leafs of interest via  
checkboxes. An example of this is the javascript Checkbox Tree available  
at [http://www.treeview.net/treemenu/3fr\_checkbox.html](http://www.treeview.net/treemenu/3fr_checkbox.html). It is also nice  
to be able to open all or close all branches via a button, and to select  
all leafs or unselect all of them.

I would rather not have to build this from scratch as I have plenty of  
other RoR work that I want to do. Thanks for any solid leads on this  
subject.

Regards,  
Mike

I did something like this, which I describe in this blog entry.

[http://blog.wolfman.com/articles/2006/05/20/role-based-authentication-admin-page](http://blog.wolfman.com/articles/2006/05/20/role-based-authentication-admin-page)

It is simple, and I have seen the set all and clear all implemented in  
java script,  
I’ll try to dig that up and add it to the blog.

I added the entry to my blog, it looks like this…

This is done with a little bit of javascript.

The view code looks like…

```
 <a href="#" onclick="checkAll('permissions_<%= controller_id %>[]'); 

```

return false;"\>all\</a\>  
\<a href="#" onclick=“uncheckAll(‘permissions\_\<%= controller\_id %\>[]’);  
return false;”\>none\</a\>

The java script is…

```
function checkAll(name)
{
	boxes = document.getElementsByName(name)
	for (i = 0; i < boxes.length; i++)
		boxes[i].checked = true ;
}

function uncheckAll(name)
{
	boxes = document.getElementsByName(name)
	for (i = 0; i < boxes.length; i++)
		boxes[i].checked = false ;
}
```
