Use tabs with the routing.
*ngFor="let link of links"
After the user has worked in Taba 1 (filled form) and switched to any other and then returned the statement Taba - namely, the component pogruzhennogo the routing is lost.
How it is solved in angular except the save statement in the service or in storage? He MatTab has a solution?
My problem zakljuchaetsja Tom - what do Label tabs should be in the same componenet. And body tabs in the other. But as you can see from the docks - the material does not allow to separate the tabs and content tabs.
