Simple Form for has_and_belongs_to_many association

[Kevin Mullaney]

I'm using Rails 4, simple_form and Zurb Foundation for styling.

I have a form which is now functioning correctly, but the select input for the association is awkward to use. Here is my form (I've bolded the relevant line):

<div class="content-box">

  <%= simple_form_for [:admin, @venue] do |f| %>

    <%= f.input :name %>

    <%= f.input :permalink %>

    <%= f.input :description, input_html: { cols: 100, rows: 6 }%>

    <%= f.input :address %>

    <%= f.input :city %>

    <%= f.input :phone %>

    <%= f.association :photos %> 

    <%= f.button :submit, class: 'small radius' %>

  <% end %>

</div>

This produced a select box that is one line and only shows one choice at a time. This is not very optimal for a select input where I might need to select half a dozen photos from the list. I tried adding "input_html: { size: '10' }", but that didn't work. Any ideas?

I think that you want is the `:multiple` option

The :multiple is set by default for has_many associations I believe.

Right, so I don't know why it is not working without trying to reproduce myself.
