Steps to reproduce the issue

  1. Having a nested sets table consisting of 1000 line. The depth of the structure is 3.
  2. Trying to load a TreeViewInput based on this structure
<?php echo TreeViewInput::widget([
                    'query'          => NetworkTree::find()->addOrderBy('root, lft');,
                    'headingOptions' => ['label' => 'Please select equipments'],
                    'name'           => 'selectedNodes', // input name
                    'value'          => $selectedNodes,
                    'asDropdown'     => false,
                    'multiple'       => true,
                    'fontAwesome'    => true,
                    'rootOptions'    => [
                        'label' => '<i class="fa fa-archive"></i>',
                        'class' => 'text-success'
                    ],
                ]);
                ?>
  1. The loading takes around 5 minutes. The problem seems to be on the client side. The genertaion of the html output is fast, but it seems parsing it through jquery takes a lot of time.

Is there any way to lazy load this?
