Tell me about custom components you have written based on the NgZorro (NzZor) library. For example, a datepicker with business restrictions on weekends.

When working with the NgZorro library, it is often necessary to create custom components that extend the basic functionality. For example, for a datepicker with business restrictions on weekends, you can do the following:

• Use the standard nz-date-picker as a base.
• Add a function that disables selecting dates that fall on weekends (Saturday and Sunday).
• Implement the nzDisabledDate method, which takes a date and returns true if the date should be unavailable.

Example:

disabledDate = (current: Date): boolean => {
  const day = current.getDay();
  // Disable Saturday (6) and Sunday (0)
  return day === 0 || day === 6;
}

In the template:

<nz-date-picker [nzDisabledDate]="disabledDate"></nz-date-picker>

Thus, you can implement business logic for date selection restrictions without changing the base component, by extending it through the NgZorro API. Similarly, more complex custom components can be created by combining the library's capabilities with your own logic.
