Extend a field within a block

I’m using the builder field and have a series of blocks for differnet layout types. One of those is a section block which can have nested blocks within it.

I have files blueprints/blocks/section.yml and blueprints/fields/blocks.yml.

I’d like to extend the blocks builder field from within the section like so

fields:
   blocks: 
      extends: fields/blocks
      label: Nested

When I attempt this the page just seems to timeout.

Is the extends value relative to the blueprints folder or its current folder? Could I do something like ./fields/blocks ?

Hey @smongey,

can you add the content of both .yml files here? The example you posted is the content of blueprints/blocks/section.yml, right?
