Our colleagues at GP Nordics did an A/B test to measure whether adding a submenu at the beginning of the posts would make people read more / engage more.

The variant with the menu was a clear winner. They chose 2 goals: scroll to bottom + pages / session (if one reads the text they are more likely to engage further in the website) and as you can see in the screenshots the variant with the menu wins by far.

This ticket is about whitelisting the submenu blocks in post types (right now it's only enabled in pages / campaigns).

No change in functionality is required, but some design work may be needed to adjust (at lea st in width) the block to the posts layouts..
