simple-form

问题 I want to change the default behavior of my submit button in simple_form so that I needn't explicitly specify :disable_with => true for all my forms.

问题 Twitter Bootstrap icons are pretty deadly seen here. Look at the bottom right hand corner of that section. See that email with an icon prepended? That is what I want to do. I want to make simple_form and boostrap play nicely. Here's what I've found that will prepend the icon to the input: = f.input :email, :wrapper => :append do = f.input_field :email <span class="add-on"><i class="icon-envelope"></i></span> But it isn't flush (that could be fixed by changing offsets in CSS) and it's pretty
