<div class="choice">
            <input type="radio" value="Рестораны/кафе" id="restaurant" v-model="position">
            <label for="restaurant">Рестораны/кафе</label>
            <input type="text" v-model="choice_numb_1">
        </div>
        <div class="choice_2">
            <input type="radio" value="Фастфуд" id="fastfood" v-model="position">
            <label for="fastfood">Фастфуд</label>

        </div>
