Dynamic tabs in Angular : navigation in dynamic tab content

i'am developing a demo app that contain a search bar, and with each search action a tab should be opened.

i succeded to do that following this awesome article <https://ift.tt/2uFPF12

the requirement is that each dynamic tab has his own context as the following images show

now inside the tab content i need to have navigation between different components.

i don't think that routing can be used, because as i mentionned, each tab has his own context.

what is the appropriate way to do so ?

any tutorials, any hint, or a place to start from would be very helpful ( i'm a beginner with angular )

thanks in advance
