How do I get rid of the div that wraps every input in a simple_form?

问题

This input:

<%= f.input :keywords, label: false, :input_html => {:class => "span8"}, :placeholder => "Park Slope, Prospect Heights, Fort Green..." %>

Produces this:

<div class="control-group string optional">
  <div class="controls">
     <input class="string optional span8" id="search_keywords" name="search[keywords]" placeholder="Park Slope, Prospect Heights, Fort Green..." size="50" type="text" />
  </div>
</div>

How do I just generate the input alone without the divs around it?

Thanks.

Well do something like this pass a params wrapper: false like this

<%= f.input :keywords, 
            label: false,
            wrapper: false,
            input_html: { class: 'span8' }, 
            placeholder: 'Park Slope, Prospect Heights, Fort Green...' %>

And See it would work

Hope this help

So it seems the best way to do this is to use f.input_field.

The docs for Simple_Form don't quite spell it out, but you can view the actual API docs here.

From the docs:

simple_form_for @user do |f|
  f.input_field :name
end

Will Produce:

<input class="string required" id="user_name" maxlength="100"
   name="user[name]" size="100" type="text" value="Carlos" />

use the regular text_field

<%= f.text_field :keywords, :class => "string optional span8", :placeholder => "Park Slope, Prospect Heights, Fort Green..." %>
