Grouping Wagtail CMS streamfield fields?

[envobe]

First of all, I wish everyone a good day.

I want to group blocks that I created with StreamField.

I am attaching an example video and image below.

Thank you for your help, best regards.

What do I want to do?

All component list

    Sub column (Component 1)
    Sub column (Component 2)
    Sub column (Component 3)

All html blocks

   Sub column (HTML block 1)
   Sub column (HTML block 2)
   Sub column (HTML block 3)

Hello - sorry for missing this issue previously. Wagtail has added a "group" argument to StreamBlock, which you can use when defining your own StreamField / StreamBlocks. https://docs.wagtail.org/en/latest/reference/streamfield/blocks.html#block-options
