spin90 and changing icon

[DatL4g]

Please add spin 90

.spin90 {
    -webkit-transform: rotate(90deg);
    transform: rotate(90deg);
}

And please provide a method to specify the icon when it's closed and when its open.

Example:
So when it's closed it shows a 'check' and when you click on it and open it the icon changes to 'close'

@DatL4g You should be able to do the icon stuff by yourself with a smiple *ngIf switch based on the open state

This is now very unlikely to be implemented, so closing.
