How to group fields in VueJs?

Question

Vue.js

Already sorted data arrives. The sort order is set in the admin panel.
I need those fields that have the same sort order to display in a specific block. Type as a group of fields.

In this screenshot, these two dropdowns should be placed one in one row if they have the same sorting.
select-buttons block in which to display such dropdowns

<div
                        v-for="item in productItem.modify"
                        :key="item.id"
                    >    
                        <div class="select-buttons " v-if=" item.modifier_id == 5 ">
                            <div class="multiselect-innner-c">
                                <multiselect
                                    :searchable="true"
                                    :show-labels="false"
                                    :placeholder="item.name"
                                    label="name"
                                    track-by="id"  
                                    :readonly="true"
                                    deselect-label="Can't remove this value"
                                    open-direction="bottom"
                                    v-model="post.dropDown[item.name_lat]" :options="item.modifire_data">
                                </multiselect>
                            </div>
                        </div>
                    </div>
