Property Description
@Input()
ngPlural: number
Write-only.

Description

Displays DOM sub-trees that match the switch expression value, or failing that, DOM sub-trees that match the switch expression's pluralization category.

To use this directive you must provide a container element that sets the [ngPlural] attribute to a switch expression. Inner elements with a [ngPluralCase] will display based on their expression:

  • if [ngPluralCase] is set to a value starting with =, it will only display if the value matches the switch expression exactly,
  • otherwise, the view will be treated as a "category match", and will only display if exact value matches aren't found and the value maps to its category for the defined locale.
