Sub-Pages/ Tabs within a Page of a Dashboard

In one of the interview, a question was asked to show the sub-pages/ tabs. :)
To hide the header banner of the application we can use custom javascript to override the default properties. This can be used in cases where we need to embed a dashboard pages/ tabs inside another page/ tab.

When the things are ready by hiding the header banner then in the dashboard page where we need to see the sub-pages/ tabs.
We first edit the dashboard page and give the embedded link

In the URL of the embedded link give the link to the page which needs to show as sub-tabs/ pages.
