Collapsing blocks on the portal

[Garret_Dark]

Hi!

Is it possible to realize sabzh or if it is implemented, then share with me a link?
For each user to turn it uninteresting or unnecessary blocks and that the re-entrance to the portal, all left as the user has selected. By the same it will reduce the load on the server.

Since it is sold in MOD Collapsible Categories.

Thank in advance and sorry for English
