How to replace a block through views?

Question

Django

Good afternoon.
We have a page with a header, menu, etc. The
main template contains templates: header, main menu and main content.
When I click on the menu links, I process them with the corresponding views.
How to render a page so that only the main content block is replaced, so that the entire page is not reloaded, but only a certain block?

Answer 1

So that the page is not reloaded, but only the block - load this block with ajax
