FloatingPortal
将浮动元素传送到给定的容器元素中 - 默认情况下,在应用根目录之外并进入主体。
¥Portals the floating element into a given container element — by default, outside of the app root and into the body.
这是必要的,以确保浮动元素可以出现在任何导致剪切的潜在父容器(例如 overflow: hidden
)之外,同时保留其在 React 树中的位置。
¥This is necessary to ensure the floating element can appear
outside any potential parent containers that cause clipping (such
as overflow: hidden
), while retaining its location in the React
tree.
提供了上下文,以便将相互嵌套的门户附加到其各自的父级。
¥Context is provided so that portals nested in one another are appended to their respective parent.
属性
¥Props
root
(可选)指定门户容器将附加到的根节点。
¥Optionally specifies the root node the portal container will be appended to.
id
(可选)选择具有 id 的节点(如果存在),或者创建它并将其附加到指定的根(默认为 document.body
)。
¥Optionally selects the node with the id if it exists, or create
it and append it to the specified root (by default
document.body
).
preserveTabOrder
默认:true
¥default: true
当使用 <FloatingFocusManager />
使用非模态焦点管理时,这将保留基于 React 树而不是 DOM 树的 Tab 键顺序上下文。
¥When using non-modal focus management using
<FloatingFocusManager />
, this will preserve the tab order
context based on the React tree instead of the DOM tree.
useFloatingPortalNode()
公开门户容器节点以供在其他组件中自定义使用。
¥Exposes the portal container node for custom use in other components.
