A placeholder in an input field usually displays a hint when the field is empty. However, in this package, the placeholder dynamically updates to show the number of items selected.

For example, if your `placeholderName` is "Employee," and one item is selected, the input will display "1 Employee selected." If your `placeholderName` is "Apple" and two items are selected, the input will display "2 Apples selected."

It should be noted that this is an optional prop. When it excluded from the component the input will show something like this e.g 2 selected.
