Say I have a normal tag being generated thusly:

```
<%= collection_select :task, :id, Task.find(:all), :id, :name %>

```

what is the easiest way to add a “ANY” option to the top of the option  
list? I know Task.find(:all) returns a collection object, so is there  
a unshift() for that?

well OK I tried:

```
 Task.find(:all).unshift([:id=>0, :name=>'ANY'])

```

but that is just a vanilla Array with “undefined method `name’”…?

thanks  
Sam

Found the answer in the source for actionpack-1.13.2/lib/action\_view/  
helpers/form\_options\_helper.rb

the :prompt option can take a value that goes atop -\>

\<%= collection\_select :task, :id, Task.find(:all), :id, “type\_name”,  
{ :prompt =\> ‘— any —’ } %\>
