Select changelog

2026-10-23: Graphic and short-label examples in complex attachments reuse Frame single-line composition and Text truncation with full-text access. Documentation only; host, clearing and selection protocols remain unchanged.

Field mode uses shared single-line layout and minimum graphics/text spacing. The invisible buttonTrigger host adds no gap; the actual Button retains content ownership.
Forward ariaLabel to the actual combobox, retaining options, native form values, return focus and custom attachments.

Fixed buttonTrigger/SelectButton list dismissal restoring focus to a noninteractive wrapper. The shared Listbox now receives the real trigger button; positioning anchors and selection behavior remain unchanged.

In the default options mode, updated option labels are reflected immediately in the selected trigger instead of retaining the previous language. The registration protocol for explicit children is unchanged.

Explicit children and custom trigger-button content no longer inherit parts configured for Select’s default children; options mode keeps its previous configuration entry points.

2026-09-21: Aligned the usage guide, source Prop table, and Site / AI reading entry. Documentation only; component behavior is unchanged.

The nonvisual buttonTrigger wrapper no longer receives a separate field border, preventing shared Field styling from overriding the real Button host variant.

When buttonTrigger has no triggerContent, it falls back to the selected option, then placeholder, then ariaLabel, avoiding an invisible empty Button.
Added a trigger ID to the Button trigger, restoring the Listbox aria-labelledby association.

The built-in dropdown indicator uses ComponentIcon name="arrow-line-up-down". Components provides it by default, while an application-level IconProvider can switch icon libraries.
The direct-child trailing-slot contract remains. A custom trailing child still replaces the default indicator.

Select-Docs.2026-05-25 Archived the historical changelog from the source header. New changes now belong in this document’s changelog; the source header retains only its role, current key architecture, and documentation path.

SEL-Break.1 Split Listbox into independent components (Listbox.svelte and MenuItem.svelte).
SEL-Break.2 Changed the API from <option> children to <Listbox> + <MenuItem> composition.
SEL-Break.3 Form submission now uses a hidden <input type="hidden">; removed the hidden <select> and MutationObserver.
SEL-Break.4 Child communication now uses ListboxOwnerContext through setContext.
SEL-Break.5 Removed multiple, nativeSize, and autocomplete Props.
SEL-Feat.2 Added readonly.

SEL-Feat.1 Replaced the native <select> with a fully custom architecture: trigger button plus fixed-position Listbox.
