v0.1.0

Upstream

• Tracks upstream commit 3260085, the same as v0.0.1, which builds on @base-ui/react v1.8.0
• The changes below are Solid-specific. The full list of differences from the React API is in the public API differences.

Breaking changes

• Popup Root render-function children are called once with { payload }, where payload is an accessor (Dialog, Alert Dialog, Drawer, Popover, Menu, Context Menu, Tooltip, Preview Card).
  Read the payload as payload().
• Combobox and Autocomplete List and Collection render functions are called once per item with item and index as accessors, like <For keyed>.
  Read them as item() and index(). Rows are keyed by the item value, so they update in place.
• *.Value render functions (Progress, Meter, Slider, Select, Combobox, Autocomplete) are called once with accessors of their arguments.
  Read them in JSX, as a returned plain string isn’t reactive.
• actionsRef and inputRef are callbacks instead of ref objects. actionsRef is called once with the actions on setup.
  Replace { current } objects with (actions) => … or (input) => ….
• container, anchor, initialFocus and finalFocus take the element itself instead of a ref object.
  Store the element in a signal from a ref callback and pass its value (null until it’s set).
• ToastObject.ref is a getter that returns the toast element.
  Call toast.ref() instead of reading toast.ref.current.
• mergeProps and mergePropsN return a reactive object like Solid’s merge, with stable merged event handlers.
  Read its properties where they’re used instead of copying them out once.
• Type parameters are Combobox.Root<Item, Multiple, Value = Item> and Select.Root<ItemValue, Multiple, Value = ItemValue>, and the value type is inferred from items when there’s no value or defaultValue.
  Reorder explicit type arguments.

Bug fixes

• Fix development builds freezing when an Accordion Item, Collapsible, Field Root, Radio or Checkbox is removed from a <For> list
• Fix useToastManager().toasts replacing a toast’s object on update, which made unkeyed <For> lists remount or loop. Toasts are now reconciled by id.
• Fix Menu item children freezing when a checkbox or radio item indicator mounts
• Fix server-rendered input parts losing defaultValue and defaultChecked when render replaces the input
• Fix the active list item not receiving focus when it’s set in the same update as the items mount
• Fix Radio Group keeping its initial id for field registration
• Fix Tabs panel registration shifting hydration keys and holding up route transitions
• Fix the Collapsible panel rendering one stale frame when its forced idle status ends

Improvements

• Infer Combobox and Select value types from items, and make the List, Collection and *.Value parts generic, for example <Combobox.List<Fruit>>
• Accept style={false}, so render function props spread on components
• Allow data-* attributes in useRender.ElementProps
• Track popup handles’ isOpen in JSX, memos and effects
• Read Autocomplete.useFilter options lazily, like Combobox.useFilter
• Log a development error pointing to a render function when render receives an element
• Halve Solid’s development diagnostics from the library by keeping memo outputs stable and deriving registrations, and name the store’s signals, memos and effects (BaseUI.Store(PopoverStore).track) so the remaining ones point to the library
• Docs: map React types to Solid types in the API references, use Solid patterns in examples, replace the React Hook Form section with Formisch, and point package documentation links at the Solid docs
