Block variations solve the usability problem of requiring clients to manually create block bindings. Create variations with pre-configured bindings that appear as separate blocks in the inserter.
Use the get_block_type_variations filter to register variations in PHP rather than requiring JavaScript. Check for the target block type, then add variation data including name, title, and pre-configured binding attributes.
The variation appears as a separate option in the block inserter but functions identically to manually bound blocks. Users simply insert the variation and start editing – the binding is already established.
This approach provides client-friendly access to complex block binding functionality without requiring technical knowledge of the underlying binding system or code editor manipulation.
