Checkbox TreeView availability ?

[mike courtney]

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. 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.

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.

Thank you for the information Jim. Pls let me know if/when you add it to
the blog.

Cheers.

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&lt;/a>
<a href="#" onclick="uncheckAll('permissions_<%= controller_id %>[]'); return false;"\>none&lt;/a>

The java script is...

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

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