Problem with <%=select%>

Rails
1

Hi all,
Today I have the following:
<%= select( “x”, “Y”, { “” => “”,“FOO” => “F” ,“BAR” => “B”}) %>

Now I have to test each item in the hash against a determined condition
and display only if the test returns true.How could I do that?

Read the documentation for Hash#select and all will become clear.
