Create a dropdown using simpleform gem

Hi guys, I'm trying to create a dropdown with preset values and label but i'm not sure how to do this. My app is currently using the SimpleForms Gem.

Here is what i'm trying to achieve.

 <select id="font-style" name="signature[font]" class="form-control">
        <option value="Helvetica, Arial, sans-serif">Helvetica / Arial</option>
        <option value="Georgia, Times, serif">Georgia / Times</option>

Though I am not a Ruby expert by any means, wouldn't you just use an f.input with the collections parameter?

<%= simple_form_for @i_dont_know_what_to_put_here do |f| %>
  <%= f.input :age, collection: { "Helvetica, Arial, sans-serif", "Helvetica, Arial, sans-serif" } %>
  <%= f.button :submit %>
<% end %>

Thanks this helped me get closer to what I needed.

  <%= f.input :font, collection: ["Helvetica Arial, sans-serif", "Georgia, Times, serif"] %>

But I still don't know how to set a name and value, i'de like the dropdown to show Serif and San-serif but when saved to save the values to the DB.

Can you pass an array to the :label argument to compliment the collection argument?

<%= f.input :font, collection: ["Helvetica Arial, sans-serif", "Georgia, Times, serif"], label: ["Serif", "Sans-Serif"] %>

I think to figure out what data is getting passed you are going to have to echo out the contents of the post call. Again, new to RoR myself, but in PHP I would do this:

    if (isset($_POST)) { echo $_POST; }

Perhaps there is some equivalent in RoR?

Didn't Work the label is for the actual field label :-/
