我如何正确使用flex-wrap？

Question

我对flex-wrap: wrap部分中的<ul>有问题，并且项目垂直对齐。有什么问题？

.c-profile_wishlist
{
    line-height: 22px;
}
.c-profile_wishlist-listing
{
    display: flex;
    justify-content: space-between;
    flex-wrap: wrap;
}

                    <div class="c-profile_wishlist">
                        <ul class="c-profile_wishlist-listing">
                            <li class="c-profile_wishlist-list_item">
                            </li>
                            
                            <li class="c-profile_wishlist-list_item">
                            </li>
                        </ul>
                    </div>

添加弹性方向：列

.c-profile_wishlist
{
    line-height: 22px;
}
.c-profile_wishlist-listing
{
    display: flex;
    justify-content: space-between;
    flex-wrap: wrap;
    flex-direction:column;
    align-items:center;
   
}

<div class="c-profile_wishlist">
                        <ul class="c-profile_wishlist-listing">
                            <li class="c-profile_wishlist-list_item">
                            </li>
                            
                            <li class="c-profile_wishlist-list_item">
                            </li>
                        </ul>
                    </div>
