I am trying to add a button that get the id of the selected list of restaurants so i can pass that id to my API request whenever i click on my button. However, i cannot add my button to the select because it disappear and i seem to be outside of the option loop in order to retrieve the id.

<div id="selectedList" class="addFavoriteRestaurantToList">
        <select  name="list_id" @change="onChange($event)" class="form-control">
              <option>--- Select a fav list ---</option>
              <option :key="listresto.id"  v-for="listresto in favoriteRestaurantData"> {{listresto.name}}</option>
        </select>
       <button class="removeButton" @click="AddFavoriteRestaurant( listresto.id, restaurantData.id)"> Add "{{restaurantData.name}}" to your your favorite list</button>
</div>

method used to return what i selected in dropbox (works but since i cant use anything on my button, im stuck) :

onChange(event) {
  return event.target.value;
}

So what i want it to get the id of the selected list to use it on my button.
