include bootstrap role attribute in rails form helper

Question

Twitter Bootstrap has this role attribute for forms:

<form role="form">

How can I include the role attribute in Rails form helpers? I tried this, but it doesn't work:

<%= form_for @user, class: "form-horizontal", role: "form" do |f| %>

Answer 1

You need to specify it as an html option:

<%= form_for @user, html: {class: "form-horizontal", role: "form"} do |f| %>
