Multiple elements with the slide-down directive in a list could be chained together to create an accordion list.

Add a way to configure the default options for all slide-down directives in a project.

A slide-down directive should be configurable so that its visible state can be persisted in localstorage and restored on page reload.

Implementation detail:

Add an [slide-down-persist]="string" input. The input value will be used as the key for storing the visible value for this element in localstorage.

ngOnInit will then check if the value of this input is set. If so, load the stored value for that key from localstorage and set the state of the directive.

I'm using [slide-down] to open some sections, but I just realised that it doesn't play well with templates and change detection in that if it's not opened the content is still rendered, just not shown. Any way to make this act the same way as a *ngIf where the content of the sub-template is not rendered?
