nz-dropdown的二级菜单nz-submenu不会自动隐藏，版本：0.6.0-rc.2

[realmx]

• 页面效果，鼠标已离开，但nz-submenu没有自动隐藏

• HTML预览，鼠标每次经过nz-submenu都会自动生成一个子ul

• HTML Code

<nz-dropdown [nzPlacement]="'topCenter'">
    <button nz-button nz-dropdown [nzShape]="'circle'">
        <i class="anticon anticon-bars"></i>
    </button>
    <ul nz-menu>
        <li nz-submenu>
            <span title>submenu</span>
            <ul>
                <li nz-menu-item>
                    <a rel="noopener noreferrer">menu-item</a>
                </li>
                <li nz-menu-item>
                    <a rel="noopener noreferrer">menu-item</a>
                </li>
                <li nz-menu-item>
                    <a rel="noopener noreferrer">menu-item</a>
                </li>
            </ul>
        </li>
        <li nz-menu-divider></li>
        <li nz-menu-item>
            <a rel="noopener noreferrer">menu-item</a>
        </li>
        <li nz-menu-item>
            <a rel="noopener noreferrer">menu-item</a>
        </li>
        <li nz-menu-item>
            <a rel="noopener noreferrer">menu-item</a>
        </li>
    </ul>
</nz-dropdown>

这个问题我也遇到了，当菜单收缩为icon时，鼠标hover效果出现叠加的子ul，期望效果是悬浮时只显示当前的子菜单（用的是最新版本的组件）
package.json如下：
"dependencies": {
"@angular/animations": "^5.0.0",
"@angular/common": "^5.0.0",
"@angular/compiler": "^5.0.0",
"@angular/core": "^5.0.0",
"@angular/forms": "^5.0.0",
"@angular/http": "^5.0.0",
"@angular/platform-browser": "^5.0.0",
"@angular/platform-browser-dynamic": "^5.0.0",
"@angular/router": "^5.0.0",
"core-js": "^2.4.1",
"ng-zorro-antd": "^0.6.0-rc.3",
"rxjs": "^5.5.2",
"zone.js": "^0.8.14"
},
原因可能是因为在移动过程中重复产生新的dom的ul,并没有移除掉之前的ul

解决方案：执行npm install @angular/[email protected]版本（用angular4.2.4）
"dependencies": {
"@angular/animations": "^4.2.4",
"@angular/common": "^4.2.4",
"@angular/compiler": "^4.2.4",
"@angular/core": "^4.2.4",
"@angular/forms": "^4.2.4",
"@angular/http": "^4.2.4",
"@angular/platform-browser": "^4.2.4",
"@angular/platform-browser-dynamic": "^4.2.4",
"@angular/router": "^4.2.4",
"core-js": "^2.4.1",
"ng-zorro-antd": "^0.6.0-rc.3",
"rxjs": "^5.4.2",
"zone.js": "^0.8.14"
},

@15136133225 感谢解答，可是4.x版本编译很慢哎，目前我坚持用着5.0，因为影响不是很严重，等版本更新吧，希望能快一点

[superestze]

5.0以上的版本也没有解决这个问题呀。在A页面点击nz-drowndown 的menu， 跳转到B页面， nz-dropdown也会出现menu

[realmx]

@superestze 看来你得重新开个issue
