Changelog

All notable changes will be documented in this file.

[Unreleased]

Added

  • Marquee [New]: Initial release of marquee component for continuously scrolling content

Fixed

  • Angle Slider: Resolved an issue where dragging the thumb from non-center positions caused unexpected value jumps. The thumb now maintains consistent positioning relative to the initial click point.

  • Slider: Fixed a problem where the thumb offset shifted dynamically during dragging, resulting in value jumps. The offset now remains constant from the pointer throughout the drag operation.

[5.26.2] - 2025-10-18

Fixed

  • Angle Slider: Fix accessibility violation where the slider thumb element lacked an accessible name. The thumb now supports aria-label and aria-labelledby props, and automatically falls back to the label element's ID for proper ARIA labeling.

  • Select: Fix accessibility violation where the required state was not set correctly to on the trigger.

  • Tags Input: Fix issue where entering a custom tag with combobox integration required pressing Enter twice. The tags-input now correctly handles custom values when the combobox has no highlighted item (aria-activedescendant is empty), allowing the tag to be added on the first Enter press.

[5.26.1] - 2025-10-15

Fixed

  • Checkbox

    • Fix issue where setting initial checked state to indeterminate doesn't work
    • Ensure api.checkedState returns the correct checked state (boolean | "indeterminate")

  • Collapsible: Fix issue where dir prop value was hardcoded to ltr instead of using the provided value

  • Combobox: Fix issue where controlled single-select combobox does not propagate its initial value to inputValue

  • Listbox: Fix issue where pressing Enter key when no highlighted item still calls event.preventDefault()

  • Radio Group: Refactor to use getBoundingClientRect() for precise indicator positioning

  • Slider

    • Fix issue where slider could stop abruptly when scrubbing thumb
    • Fix issue where range slider thumbs become stuck when dragged to the same position without minStepsBetweenThumbs

  • Tabs: Refactor to use getBoundingClientRect() for precise indicator positioning

  • Tags Input: Fix issue where maxLength doesn't apply to the edit input as well

[5.26.0] - 2025-10-08

Added

  • Collapsible: Add support for collapsedHeight and collapsedWidth props to control the dimensions of the collapsible content when in its collapsed state.

  • Focus Trap: Allow elements referenced by aria-controls to be included in the trap scope. This makes it possible for menus, popovers, etc. to be portalled and work correctly.

  • Pagination: Add getPageUrl prop for generating href attributes when using pagination as links.

const service = useMachine(pagination.machine, {
  type: 'link',
  getPageUrl: ({ page, pageSize }) => `/products?page=${page}&size=${pageSize}`,
})

  • Select: Add SelectRootComponentProps type export for better component type composition.

  • Listbox: Add ListboxRootComponentProps type export for better component type composition.

  • Combobox: Add ComboboxRootComponentProps type export for better component type composition.

  • TreeView:

    • Add TreeViewRootComponentProps type export for better component type composition.
    • (Experimental) Add support for node renaming functionality:
      • Add TreeViewNodeRenameInput component for inline node label editing
      • Add canRename prop to control which nodes can be renamed
      • Add onRenameStart, onBeforeRename, and onRenameComplete callbacks for rename lifecycle
      • Add CheckedChangeDetails, LoadChildrenErrorDetails, RenameStartDetails, and RenameCompleteDetails type exports

Fixed

  • Scroll Area: Fix RTL horizontal scrollbar positioning on Safari

  • Slider: Fix issue where slider continues dragging when disabled during drag operation.

  • Switch: Fix issue where data-active is inconsistently applied when disabled state changes at runtime

[5.25.1] - 2025-09-27

Fixed

  • Date Picker

    • Fix issue where year range picker doesn't show the hovered range
    • Fix issue where quarter presets returns incorrect date

  • FormatByte: Add support for unitSystem property to allow changing between decimal (1000 bytes) and binary (1024 bytes) systems.

  • Number Input: When formatOptions is used (like style: "currency"), the cursor would jump to the end of the input when typing in the middle. The cursor now maintains its relative position during formatting changes.

  • Pin Input: Fix issue where using the keyboard shortcuts Cmd+Backspace and Cmd+Delete to delete text in pin inputs would insert "undefined" instead of clearing the field.

  • Scroll Area: Fix issue where resize tracking was not observing the root element, which caused the scrollbar to not update when the root element's size changed.

[5.25.0] - 2025-09-16

Added

  • Added mergeProps utility for combining multiple props objects with proper event handler and className merging.
  • Added createContext utility for creating typed React contexts with improved DX.
import { createContext } from '@ark-ui/react/utils'

Fixed

  • AngleSlider: Export angleSliderAnatomy from the anatomy exports

[5.24.1] - 2025-09-14

Fixed

  • General: Fix issue where mergeProps throws when props is undefined or null

[5.24.0] - 2025-09-14

Added

  • Combobox: Add alwaysSubmitOnEnter prop to allow bypassing the default two-step behavior (Enter to close combobox, then Enter to submit form) and instead submit the form immediately on Enter press. This is useful for single-field autocomplete forms where Enter should submit the form directly.

  • Dismissable: Add support for layer types in dismissable layer stack. Layers can now be categorized as dialog, popover, menu, or listbox. This enables:

    • data-nested attribute on nested layers of the same type
    • data-has-nested attribute on parent layers with nested children of the same type
    • --nested-layer-count CSS variable indicating the number of nested layers of the same type

Changed

  • Hover Card: Change default delay values for hover card to improve accessibility.

    • openDelay: from 700ms to 600ms

  • Tooltip: Change default delay values for tooltip to improve accessibility. Learn more

    • openDelay: from 1000ms to 400ms
    • closeDelay: from 500ms to 150ms

Removed

  • TimePicker: The TimePicker component has been removed from this release. This component was never part of the public API and was considered experimental. It had significant bugs and usability issues across all frameworks and locales, making it unsuitable for production use.

    Migration: We recommend building a custom time picker using the Select component for simple use cases, or implementing a time grid pattern for more complex scenarios.

Fixed

  • Editable: Allow text selection in editable preview when autoResize is enabled

    Previously, when autoResize was set to true, the preview element had userSelect: "none" applied, preventing users from selecting text. This has been fixed by removing the userSelect style property.

  • File Upload: Fix regression where clicking the trigger doesn't open the file picker when used within the dropzone

  • Menu:

    • Fix issue where keyboard activation of menu items with target="_blank" would open two tabs
    • Fix issue where hovering a partially visible item with pointer causes it to scroll into view

  • Tabs: Fix issue where ids for item and content could not be customized

  • Toast: Allow creating a toast store without any arguments

[5.23.0] - 2025-09-08

Added

  • Field: Add data-required attribute to Field.Label
  • Select, Combobox, Listbox, TreeView: Export RootComponent and RootProviderComponent types which are useful when building compositions that wrap the Root and RootProvider components and you still want type-safety for the collection.

Fixed

  • Menu: Fix Menu.ItemText not working inside Menu.TriggerItem

    import { Select } from '@ark-ui/react/select'
import { styled } from 'styling-lib'

const Root = styled(Select.Root) as Select.RootComponent<{}>

[5.22.0] - 2025-08-28

Added

  • Combobox: Add ComboboxEmpty component to display content when the combobox has no items

  • Color Picker: Fix issue where color picker was not working correctly in RTL mode

  • Date Picker: Fix issue where datepicker doesn't revert to a valid value when the input value exceeds the min/max and blurred

  • Dismissable: Expose onRequestDismiss custom event handler for event a parent layer requests the child layer to dismiss. If prevented via event.preventDefault(), the child layer will not dismiss when the parent layer is dismissed.

  • Number Input

    • Omit the input pattern when formatOptions is provided. This prevents native pattern validation from conflicting with formatted values (e.g., currency or percent).
    • Handle empty values consistently across all format options.
    • Add data-scrubbing attribute to the number input parts.

  • Tags Input: Fix issue where highlighted item doesn't clear when tabbing out of the input to an external button within the control part.

  • Tooltip

    • Set closeOnPointerdown to false when closeOnClick is set to false
    • Reduce bundle size by replacing @zag-js/store dependency with a lightweight store implementation.

    • Fix issue where first enabled item should be highlighted by default when listbox receives focus and no item is currently highlighted.
    • Add getElement to scrollToIndexFn details
    • Track collection changes and clear highlightedValue if the item is no longer in the collection.

    Hover range states are only active when not overlapping with actual selected range, enabling distinct styling for hover preview vs actual selection in range mode.

Fixed

  • Date Picker: Fix date comparison issues when time components are involved. This resolves critical issues with date comparison operations when different date types (CalendarDate, CalendarDateTime, ZonedDateTime) are mixed, particularly in scenarios involving time components.

[5.0.0] - 2025-03-06

Ark UI just got a major performance boost! 🚀

What’s new in v5?

  • Blazing-fast performance – Every component runs smoother and renders faster.
  • Smaller bundle size – Leaner components and adapters for a more efficient build.

We made this happen by using React’s native reactive primitives instead of external stores.

In our stress tests with 10,000 components, Ark v5 delivered 1.5x–4x better performance across the board.

Performance comparison showing Ark v5 is 1.5x-4x faster than other libraries

A quick note on tests

Most component updates are non-breaking, but due to this change, some tests may need adjustments. For example:

// Before
it('should open by default', () => {
  render(<ComponentUnderTest defaultOpen />)
  expect(screen.getByRole('dialog')).toBeInTheDocument()
})

// After
it('should open by default', async () => {
  render(<ComponentUnderTest defaultOpen />)
  expect(await screen.findByRole('dialog')).toBeInTheDocument()
})

Added

  • Carousel: ⚠️ Breaking change: Added required prop slideCount to Carousel.Root component.
  • Clipboard: Added onValueChange and defaultValue props.
  • ColorPicker: Added defaultFormat prop.
  • Combobox: Added defaultHighlightedValue and defaultInputValue props.
  • DatePicker: Added defaultFocusedValue prop, getViewProps, and visibleRangeText.
