TreeSelect
Designer doc
TreeSelect is an input component to select a value from an tree-structure option list.
Example
Basic Usage
Select
View code
An icon button can be used to trigger dropdown selection too.

Rendering from data
Different from Ant Design’s TreeSelect, Coral’s doesn’t include tree rendering from data inside the component, rather a utility function renderFromData is provided.

Client-side search
In case you want to search locally within a tree, instead of using TreeSelectNode or renderFromData, you can use TreeSelectSearchableNodes inside TreeSelectList.
This component handles nodes pruning and expandedValues based on searchValue and the data you provided (same schema as utility function renderFromData). You only need to pass data prop and filter function.
Client side search
Search
View code
Note that searching in TreeSelect is a really complicated thing - ease of usage has some tradeoffs with flexibility, and TreeSelectSearchableNodes chooses for the former. While TreeSelectSearchableNodes component should never introduce any breaking changes, another new search component may be created if this component cannot cover all use cases.
Managing client-side search
By default, TreeSelectSearchableNodes will set expandedValues state to display all matched search nodes on every searchValue changes.
To customize a little bit how the expand state behaves, you can pass:
- resetExpandedTo: array of values. This is different from expandedValues and initialExpandedValues in TreeSelect because this is triggered on query changes.
- skip: either boolean or function accepting query. If the result is true, it includes all nodes and will set expandedValues to resetExpandedTo.
That said, the default value of resetExpandTo is [] (empty array), and skip is query => !query.length.
Below is an example of “Search only if query has more than 3 characters”.

Accessibility
- Right arrow:
- When focus is on a closed node, opens the node; focus and selection do not move.
- When focus is on a open node, moves focus to the first child node and selects it if it is selectable.
- When focus is on an end node, does nothing.
- Left arrow:
- When focus is on an open node, closes the node.
- When focus is on a child node that is also either an end node or a closed node, moves focus to its parent node and selects it if it is selectable.
- When focus is on a root node that is also either an end node or a closed node, does nothing.
