<%= f.association :opportunity_status, :label => \"Status\", :input_html => {} %> <%= f.select :source_type, options_for_select([\"lead\",\"vteam\"],[
This is because f.select is not a simple_form method and does not support :label
This should work for you w/ simple form
<%= f.input :source_type, :label => "Lead or VTeam", :collection => ["lead","vteam"], :selected => "lead" %>
Hope this helps
