我在我创建的菜单中写了一个过滤函数，但是除了“所有菜单”之外，还有一些错误。换句话说，它把一个菜单的两个元素中的一个放在最右边，另一个放在最左边。但是我想让它们并排放置。我该怎么做呢？我想我在css代码中犯了一个错误，但是我找不到我犯错误的地方。
const liItem = document.querySelectorAll('ul li');
const imgItem = document.querySelectorAll('.product img');
liItem.forEach(li => {
li.onclick = function(){
//active
liItem.forEach(li => {
li.className = '';
})
li.className = 'active';
//Filter
// console.log(li.textContent);
const value = li.textContent;
imgItem.forEach(img => {
img.style.display = 'none';
console.log(img.getAttribute('data-filter'));
if (img.getAttribute('data-filter') == value.toLowerCase() || value == 'All Menu'){
img.style.display = 'block';
}
})
}

我将与你分享我的代码的最新版本。整个菜单选项没有问题，但是当我切换到其他菜单时，我仍然有问题显示它，因为其他菜单中的项目很少。如果有足够的图像不占满整行，我希望它们从左边开始排序。我该怎么办？
