Displays the "Core Size (mm)" field in the edit and overview page only if it has a value. Explaination: Uses the double negation (!!) to check whether core_size_mm has a true value.
If core_size_mm is empty, null, or undefined, this condition will evaluate to false, preventing the field from displaying in edit and overview page. |
