Menú de acordeones, sintaxis extraña

Recuperé un código de Stackblitz

No entiendo esta línea:

 [style.height.px]="menu.active?submenu.scrollHeight: 0">

¿Hay alguna manera de escribir esto con otra sintaxis?

Aquí está el código

 <ul class="submenu" #submenu [style.height.px]="menu.active ? submenu.scrollHeight : 0"> <li *ngFor="let submenu of menu.submenu"> <a [href]="submenu.url">{{ submenu.name }}</a> </li> </ul>

Puedes hacerlo con la directiva de atributo ngStyle :

 [ngStyle]="{ 'height.px': menu.active ? submenu.scrollHeight : 0 }"

Así que el código final se verá así:

 <ul class="submenu" #submenu [ngStyle]="{ 'height.px': menu.active ? submenu.scrollHeight : 0 }"> <li *ngFor="let submenu of menu.submenu"> <a [href]="submenu.url">{{ submenu.name }}</a> </li> </ul>
