I need an editable combo box for a rails app where I can select from a
list of values from the DB or have the user input a new one. Doing a
plain old list box with options from the DB is easy. Can someone please
direct me to info on the best way to do this? Will I need to resort to
JavaScript to get it done?
Thanks in advance.

I don't think there's a way to do it without Javascript.

I've used the one at
http://www.xaprb.com/blog/2005/09/29/javascript-combo-box/

And then used this in the form-
<td><label for="invoice_project_name">Project name</label><br/>
<%= @projects=Invoice.find_by_sql(["select distinct project_name from
invoices where client = ? order by
project_name",@invoice['client']]).map {|u| [u.project_name,
u.project_name]}
@projects=@projects.unshift(@invoice['project_name'])
select(:invoice, :project_name, @projects, { },
{:onkeypress=>"edit(event);", :onblur=>"this.editing=false;"})%></td>
