* <mdui-navigation-bar>
* ..<mdui-navigation-bar-item icon="place">Item 1</mdui-navigation-bar-item>
* ..<mdui-navigation-bar-item icon="commute">Item 2</mdui-navigation-bar-item>

*
* @slot - 导航项文本
* @slot icon - 图标
* @slot active-icon - 激活状态的图标元素
* @slot badge - 徽标
*
* @event focus - 获得焦点时触发
* @event blur - 失去焦点时触发
*
* @csspart container - 导航项容器
* @csspart indicator - 指示器
* @csspart badge - 徽标
* @csspart icon - 图标
* @csspart active-icon - 激活状态的图标
* @csspart label - 导航项文本
*
* @cssprop --shape-corner-indicator - 指示器的圆角大小。可以指定一个具体的像素值；但更推荐引用[设计令牌](/docs/2/styles/design-tokens#shape-corner)
