It doesn't block the initial rendering but it is possible to see the items being expanded.

This implies some performance problems because the component only knows about the selectedKeys and the items, and will have to traverse the entire tree to find the selected items and the path to the parent item to expand it. Selection hydration is the ability for the TreeView to expand the parent items of the selected items when the component performs the first render. This section helps with some good practices that help the TreeView remain responsive. Internally, the component handles everything without the developer having to worry about making implementation adjustments, but in some scenarios, it may be necessary for the developer to follow good practices to avoid a performance degradation. The TreeView component was designed with performance in mind. In which case onItemsChange is called with the tree is updated. If the user presses the Backspace or Delete key the TreeView removes the item from the items structure. The component consumes the data using the items property.įor the component to be dynamic it is necessary to convert children to render prop, which must be a function that will receive the item of the current iterator.įunction Example ( ) Remove Item The TreeView and Group components when used with dynamic items are populated from hierarchical data. It allows more flexibility with the names of the properties to be rendered and avoids creating APIs to change those properties. This is essential for the component to be data agnostic. It uses a very common technique in React.js components called render props whose value is a function that will receive some data. ContentĪs TreeView is middle-level, it allows you to build static or dynamic content if you need to consume data from some service. It's also easy to move from low-level to high-level quickly and the APIs are more consistent. This component follows a slightly different thought from our low-level and high-level philosophy, we consider this to be a middle-level component that allows you to build the two in one, allowing flexibility and adding features that you wouldn't have in a low-level. It was built with performance in mind, which influences API design and feature implementations. The TreeView component is designed to display data using a hierarchical structure.
