Provide automatic links to block examples or other block examples

[bobbingwide]

Similar to the variations links, where we use the blockinfo block to display links to variations of the block, it would be nice to display (other) examples for a Block or other Block examples for a Block example.

Requirement

• For a Block display a list of links to (other) block examples, if there are any.
• For a Block example display a list of links to other block examples, if there are any.
• Do this automatically for each Block or Block example
• Don't display a heading if there aren't any results.

Proposed solution

• A template part for other_block_examples
• Implementation to make use of the [bw_related] shortcode.

bw_related shortcode

For Blocks the bw_related shortcode that's required is:

[bw_related post_type=block_example]

For other Block examples we can implement the equivalent of this shortcode

[bw_related post_type=block_example meta_key=_block_ref meta_value=_block_ref]
