Dropdown

A dropdown list.

If there are too many operations to display, you can wrap them in a Dropdown. By clicking/hovering on the trigger, a dropdown menu should appear, which allows you to choose one option and execute relevant actions.

import { NzDropDownModule } from 'ng-zorro-antd/dropdown';
