Question

in my case I want to show overflow in horizontal direction to scroll or auto but in vertical direction... I want to visible it without scroll. (may be image clear this). Is here any way to solve it with CSS or JavaScript.

那个滚动条不应该在那里，因为我们现在正在使用 javascript 所以使用 wheel 事件滚动并避免滚动条这是最终产品我相信你想要什么

const main = document.querySelector(".wrapper")
main.addEventListener("scroll",e=>{
    const subs = main.querySelectorAll(".nav > .each > .sub-menu")   
    subs.forEach(sub=>{
        let parent = sub.closest(".each"),
            parentX = parent.getClientRects()[0].x
        sub.style.left = parentX + "px"
    })
})

main.addEventListener("wheel",e=>{
    e.preventDefault()
    let speed = 0.4
    main.scrollBy(e.deltaY * speed,0)
})

.each:hover > .sub-menu {display: block !important;}
.sub-menu{display: none;}
.nav .sub-menu > .each > .sub-menu {
    left: 100%;
    top:0px;
}
.wrapper {
    width: 320px;
    overflow-x: hidden;
    overflow-y: hidden;
}
.title {width: max-content;}
.each {
    background:white;
    cursor: pointer;
}
.each:hover {background:rgb(194, 194, 194);}
.nav {border:1px solid black;}
