I’m using a dropdown on my form for a simple cms which displays the  
pages from the database. I want to add some options to the dropdown  
that are not in the database. Is there a way to do this?

Here’s my code so far:

Link  
\<%= select("navigation", "link", Page.find\_all.collect {|p| [p.title, p.id] }) %\>

What I want is to add in a link called “listings” that is not in the  
table as well as a link called “home”. I’m giving the user the option  
to choose the display order, so it doesn’t matter where they show in the  
dropdown. However, it would be nice to have it still autoselect the  
appropriate item in the edit form.

try something like this:

 Home \<%= option\_groups\_from\_collection\_for\_select Page.find\_all, 'id', 'title' %\>
