Conditional Field Visibility

Control the visibility of individual fields based on the values of other fields or the current view mode. Supports all, any, not_all, not_any logic blocks, regex field matching, and embedded item conditions.

Pattern 1: Simple Field-to-Field Condition

!defs(extra_options_show_if_pattern_1_simple_defs.yaml)

Pattern 2: Combined Conditions

!defs(extra_options_show_if_pattern_2_combined_defs.yaml)

Pattern 3: Embedded Item Condition

!defs(extra_options_show_if_pattern_3_embedded_item_defs.yaml)

Pattern 4: Nested Embedded Conditions

!defs(extra_options_show_if_pattern_4_nested_embedded_defs.yaml)

Pattern 5: Regex Key

!defs(extra_options_show_if_pattern_5_regex_defs.yaml)

Pattern 6: Submit Button Visibility

!defs(extra_options_show_if_pattern_6_submit_button_defs.yaml)

Each top-level show_if entry must be a hash of conditions. Field keys may be literal field names, regex keys, or submit_buttons_<button_id>.
