How to animate <select> list on opening it by using fadeInDown of animate.css? I don't want to use <ul> tag and jQuery for this purpose as I am using angular with typescript.
You can't animate options from a select tag (or I'm not aware of it).
For all I know, this is handled directly by the browser. That's why you can't style the options either.
If you want to animate it and style the options, you will have to make custom component, such as the Material dropdown select
