Entry within multiple sections

Question

I'm trying to work out if the following is possible in Craft.

Assuming I have a single entry, I want to theoretically tag it as a 'blog' and 'about', both of which are sections I want to then have that entry displayed within both the blog, and the about sections.

From what I can tell an entry is constrained to it's parent section. But is this possible using tags or something similar?

Ideally a craft2 answer, as the site is being developed in craft 2, with the plan to upgrade to craft3 in the summer.

Thanks!

UPDATE

I feel like I need to describe the problem more, with an example.

Say I have an entry called 'Meet the team', and two sections 'England' and 'U.S.A', the country sections act like normal structure sections - but the Staff Team entry is applicable to both sections.

Is it possible when displaying the England entries to display the Staff Team entry in addition to the USA entries to display the Staff Team entry?

The site in development is planning on having many of these types of pages - so a hard-coded solution to 'get' the post isn't possible.

Another way of describing it is the Wordpress way, of having 1 page in multiple categories, so each category shows that page.

Answer 1

When it's only for frontend: you can search for entries from different sections with

set entries = craft.entries.section(['blog', 'about', 'foo']).find()

This returns you all enabled/active entries from all the sections with the handle blog, about or foo.
