  }

Any Update on this? I am seeing all content within my tabs load instantly and not when the tab is active. As mentioned above [lazyLoad] does not change the functionality:

Hi, guys! Any update on this? For now, with [lazyLoad]="false" content is not rendered in the template but all hooks (calls to backend, etc) in child components are still executed. Is there a way to restrict this completely until tab is selected first time? This is pretty annoying in case we have a lot of tabs.
