  <p>( <a href="https://apidock.com/rails/ActionView/Helpers/FormTagHelper/select_tag" rel="nofollow noreferrer">https://apidock.com/rails/ActionView/Helpers/FormTagHelper/select_tag</a> )</p>
  
  <p>What I tried</p>
  
  <pre><code>&lt;%= select_tag "near_within_distance",                                                                       
      options_for_select([                                                                                     
      ["Male", "50m "],                                                                                        
      ["Female", "f"],                                                                                         
      ], params[:near_within_distance]),                                                                       
      class: "form-control zcustom-select mr-sm-1",                                                            
      include_blank: "&lt;i class='fa fa-search'&gt;&lt;/i&gt;".html_safe %&gt;    
  </code></pre>
  
  <p>Resulted in</p>
  
  <pre><code>&lt;select name="near_within_distance" id="near_within_distance" class="form-control zcustom-select mr-sm-1"&gt;&lt;option value=""&gt;&lt;/option&gt;&lt;option value="50m "&gt;Male&lt;/option&gt;
  &lt;option value="f"&gt;Female&lt;/option&gt;&lt;/select&gt;
  </code></pre>
