                    <div class="control">
                         <div class="select  is-primary">
                             <select name="eye_color">
                                    <option value="">Not Given</option>
                                    <option value="Blue" >Blue</option>
                                    <option value="Brown" >Brown</option>
                                    <option value="Green">Green</option>
                                    <option value="Hazel" >Hazel</option>
                                    <option value="Grey" >Grey</option>
                                    <option value="Dark brown">Dark brown</option>
                                    <option value="Rather not say" >Rather not say</option>
                                    <option value="Other">Other</option>
                             </select>
                          </div>
                     </div>
          </div>



              <div class="field">
                     <label class="label"><strong class="has-text-grey">Smoke </strong></label>
                           <div class="control">
                              <div class="select is-primary">
                                 <select name="smoke">
                                 <option value="" >Not Given</option>
                                 <option value="No" >No</option>
                                 <option value="Yes, socially" >Yes, socially</option>
                                 <option value="Yes, regularly" >Yes, regularly</option>
                                 <option value="Rather not say" >Rather not say</option>
                                 </select>
                              </div>
                           </div>
                        </div>



</form>

Step: 2 SearchController.php

 public function PostSearch(Request $request)
 {

     $filters = [
            'eye_color' => Input::get('eye_color'),
            'drink'    => Input::get('drink'),
        ];
     
      $user = User::where(function ($query) use ($filters) {
            if ($filters['eye_color']) {
                $query->where('eye_color', '=', $filters['eye_color']);
            }
             if ($filters['smoke']) {
                $query->where('smoke', '=', $filters['smoke']);
            }
        })->get();

    return $user;
  }

Here we try to show with two fields, the query filter eye_color  apply on the filter when user select. so here we complete post on Laravel advance search filters with optional fields.
