false
nil

Anchor to allow_false

allow_false

variable | default: variable, allow_false: boolean

By default, the default filter's value will be used in place of false values. You can use the allow_false parameter to allow variables to return false instead of the default value.

{%- assign display_price = false -%}

{%- assign display_price = false -%}

{{ display_price | default: true, allow_false: true }}

Output

false
