Composite block from multiple other blocks + layout I would like to create a block consisting of multiple other blocks, combined with a layout or some other kind of wrapper html.

A typical example would be a footer with 4 columns containing a menu, some custom text, etc.

The entire thing should be configurable in the UI and then exportable to the CMI system.

Known solutions

I know that this is possible in Drupal 7 using renderkit + cfrblock. However this has not been ported to Drupal 8 (yet). I will get there eventually, but atm I would like to find out if another solution might already exist.

EDIT:
On D8 there is blockgroup, but it does not really work for me.

How to group multiple blocks into one big block I think this is for D7.

Thanks!
Use blockgroup. Add block_class if needed.

When creating the block groups, make sure that the machine name does not clash with existing theme region machine names! (from any theme, ideally)

After you created a block group, it will show up in two ways in the blocks UI:


As a new theme region (if you avoided the name clash)
As a block that can be placed.


Block class allows to add classes (e.g. bootstrap grid classes) to each block and block group.

This is not 100% what you would get with a layout, but it is getting close, and will be sufficient in many cases.
