                        @endif
                        @livewire('load-more-user-list')
                    </div>
                </div>
            </div>
        </div>
    </div>
    @livewireScripts
    <script type="text/javascript">
        window.onscroll = function(ev) {
            if ((window.innerHeight + window.scrollY) >= document.body.offsetHeight) {
                window.livewire.emit('load-more');
            }
        };
   </script>
</body>
