block_core_navigation_render_fallback │ filter-hook │ WP 5.9.0

Filters the fallback experience for the Navigation block.

Returning a falsey value will opt out of the fallback and cause the block not to render. To customise the blocks provided return an array of blocks - these should be valid children of the core/navigation block.

Usage

function wp_kama_block_core_navigation_render_fallback_filter( $fallback_blocks ){
