try putting #panels div outside foreach loop - way in same group.

also, #panels div should not have "#" sign in id.

<?php if(!empty($tickets)) : ?>      <div class="panel-group-custom" id="panels"><!-- remove '#' here. -->         <?php foreach($tickets $ticket) : ?>         <div class="panel panel-default mb-0 no-border">             <div class="panel-heading panel-heading-custom" ><!-- , remove . here. -->             <h4 class="panel-title">               <div data-toggle="collapse" data-parent="#panels" data-target="#collapse<?php echo $ticket['supportticket']['id'] ?>" class="accordion-title">                   <div class="row">                       <div class="overflow-hidden">                           <div class="col-md-2">                               <span class="ticket-heading1" title="ticket id"><i class="fa fa-ticket" aria-hidden="true"></i> <?php echo $ticket['supportticket']['ticket_id']; ?> </span>                           </div>                           <div class="col-md-7"><span class="ticket-title"><?php echo $ticket['supportticket']['title'] ?></span></div>                           <div class="col-md-2">                               <span class="ticket-heading2" title="ticket created on"><i class="fa fa-calendar" aria-hidden="true"></i>                                    <?php $bdate = date_create($ticket['supportticket']['modified']); ?>                                          <?php echo date_format($bdate,"d-m-y") ?>                                        </span>                           </div>                           <div class="col-md-1">                               <span class="accordion-down">                                 <i class="fa fa-chevron-down dropdown-toggle down-arrow2" aria-hidden="true"></i>                             </span>                           </div>                       </div>                   </div>               </div>             </h4>           </div>           <div id="collapse<?php echo $ticket['supportticket']['id'] ?>" class="panel-collapse collapse">                 <div class="panel-body">                     <div class="hidden-overflow ticket">                          <div class="full-width hidden-overflow ticket-chat">                              <p class="color-4 ticket-content">                                  <?php echo $ticket['supportticket']['description'] ?>                                                               </p>                              <?php if($ticket['supportticket']['status']>1) : ?>                              <p class="color-1 pull-right ticket-content"> <span class="resolution">feedback</span>                                                  <?php echo $ticket['supportticket']['resolution_text']; ?>                                  <span class="ticket-updated"><span class="bolder"><i class="fa fa-clock-o" aria-hidden="true"></i>                                         <?php $bdate = date_create($ticket['supportticket']['modified']); ?>                                                <?php echo date_format($bdate,"d-m-y") ?>                                            </span></span>                               </p>                               <?php endif ?>                          </div>                          <div class="full-width hidden-overflow mt-5">                         <!-- <p class="ticket-close"><i class="fa fa-window-close" aria-hidden="true"></i> closed on <span class="bolder">17-aug-2017 </span></p>-->                          </div>                      </div>                  </div>              </div>         </div>         <?php endforeach ?>     </div><!-- end #panels (moved after foreach) --> <?php else : ?>     no records <?php endif ?>

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
