html - How to render partial form as a horizontal form in rails 4 -

-

i have partial (triggered ajax) on main page consists of form. form displayed horizontally rather vertically. have tried such wrapping in <form class="form-inline"> i've tried <%=f.number_field :pointsspend, :class => "checkbox inline"%> , altering css display: inline none of seems work

the main form in partial rendered:

 <div class="row">         <div class="col-md-12">             <%= link_to image_tag("biceps.jpg"),'#', id: 'challengebutton', class: "btn btn-lg btn-primary" %>             <div id="challengecentre"></div>         </div>     </div>

the form

<%= form_for(@challenge) |f| %>    <% if @challenge.errors.any? %>     <div id="error_explanation">       <h2><%= pluralize(@challenge.errors.count, "error") %> prohibited challenge being saved:</h2>        <ul>       <% @challenge.errors.full_messages.each |message| %>         <li><%= message %></li>       <% end %>       </ul>     </div>   <% end %>    <div class="field">     <%= f.label :pointsspend %><br>     <%= f.number_field :pointsspend %>   </div>   <div class="field">     <%= f.label :rules %><br>     <%= f.text_area :rules %>   </div>    <div class="actions">     <%= f.submit %>   </div> <% end %>  </form>

you should able pass class form_for method this:

<%= form_for(@challenge, html: { class: 'form-inline' }) |f| %>    <% if @challenge.errors.any? %>     <div id="error_explanation">       <h2><%= pluralize(@challenge.errors.count, "error") %> prohibited challenge being saved:</h2>        <ul>       <% @challenge.errors.full_messages.each |message| %>         <li><%= message %></li>       <% end %>       </ul>     </div>   <% end %>    <div class="field">     <%= f.label :pointsspend %><br>     <%= f.number_field :pointsspend %>   </div>   <div class="field">     <%= f.label :rules %><br>     <%= f.text_area :rules %>   </div>    <div class="actions">     <%= f.submit %>   </div> <% end %>  </form>
