Question

I am trying to apply a class to a select form element that is built with Ruby.

Here is the f.select:

<%= f.select :within, ["5km", "50km", "100km", "250km", "500km", "1000km"], { :include_blank => 'Anywhere', :selected => (params[:listing][:within] unless params[:listing].nil? || !params[:listing].has_key?(:within)) } %>

Where does the class go? My class is:

:class => 'input-medium'

Thanks!

Answer 1

See the documentation, specifically the html_options argument.

Add yet another argument onto the end of what you’ve posted in your question with:

{ class: "input-medium" }

Altogether that’s

<%= f.select :within, ["5km", "50km", "100km", "250km", "500km", "1000km"], { :include_blank => 'Anywhere', :selected => (params[:listing][:within] unless params[:listing].nil? || !params[:listing].has_key?(:within)) }, { class: "input-medium" } %>
