[Vuejs]-How to make selectable items

If its one state (e.x when you select you cannot toggle it back), then just remove the item parameter and convert the method like that

chooseBreakfast() {
  this.itemSelected = true
}

If you need to have a toggle state remove again the item parameter and convert the method like that

chooseBreakfast() {
  this.itemSelected = !this.itemSelected
}

Also remove from the @click handler the item param in both cases
