Multiple animation triggers in angular2 Component

Question

I would like to define multiple animation triggers in one component. Is this possible?

For example one for entering the scene and one for hover. Or do I need to define two components (parent child) for this case?

item.compoennt.ts

// removed the import and class part for better readability

@Component({
  selector: 'item',
  templateUrl: './item.template.html',
  styleUrls: ['./item.style.scss'],
  animations: [
    // page load animation 
    trigger('slideIn', [
        state('in', style({
            opacity: 1,
            transform: 'translateY(0)'
        })),
        transition('void => *', [
            style({
                transform: 'translateY(100%)',
                opacity: 0
            }),
            animate('0.5s 100ms ease-in')
      ])
    ]),


    // <--- this fails
    // hover animation
    trigger('fadeIn', [
      state('over', style({
            opacity: 1
        })),
        transition('void => *', [
            style({
                opacity: 0
            }),
            animate('0.5s 100ms ease-in')
    ])
  ],
})

item.template.html

<div class="item" [@slideIn]="enterState">

    <div class="info">
        SOME INFO
    </div>
    <div class="info-on-hover" [@fadeIn]="hoverState">
        SOME INFO 
    </div>
</div>  

Oh and someone should create the tag "angular2-animation"

Yes you can have as many triggers as you need.

You can also have multiple states in one trigger not just two. So you can for example have a 'enter' state and a 'hover' state with different transitions between the states.

For example:

state('in', style({opacity: 1,
            transform: 'translateY(0)'
        })),
state('hover', style({background: 'red'}),
transition('* <=> hover', animate('200ms ease-in'))
