Convert SelectField component to TypeScript

This PR converts src/components/select-field from JavaScript with Flow to TypeScript.

Changes

  • Converted BaseSelectField, MultiSelectField, SelectField, SelectFieldDropdown, and SingleSelectField to .tsx with exported *Props interfaces
  • Converted index.js to index.ts, re-exporting the public components and their types
  • Converted props.js to props.ts with exported SelectOptionProp / SelectOptionValueProp
  • Converted __tests__/*.test.js to *.test.tsx
  • Created .js.flow files for backward compatibility

Contract

  • Declared Flow props contract preserved (requiredness, accepted values, defaults, exports)

Testing

  • Ran tests for src/components/select-field; all 113 pass with existing snapshots matching previous output
  • yarn lint:ts and flow check pass

Summary by CodeRabbit

  • New Features

    • Added single-select and multi-select fields with customizable options and rendering.
    • Added search filtering, keyboard navigation, clear options, separators, and configurable dropdown alignment and scrolling.
    • Added localized labels for searching, clearing selections, and no-result states.
    • Added accessible listbox behavior, active-option tracking, and outside-click dismissal.
    • Added form integration that automatically updates selected values.
  • Tests

    • Updated select-field coverage and assertions for TypeScript compatibility.

Align buttonText with the button title contract. renderButtonText() can return React.ReactNode, but SelectButtonProps.title accepts only string. Typing buttonProps directly will therefore fail the lint:ts check at title: buttonText. Pass only strings to the HTML title attribute, then remove the assertion.

...
-            title: buttonText,

...

Export the select-field types from the Flow barrel. The published Flow sidecar currently exports only the three components, while index.ts exposes SingleSelectFieldProps, MultiSelectFieldProps, SelectFieldProps, SelectOptionProp, and SelectOptionValueProp. Flow consumers importing these types from box-ui-elements/es/components/select-field will receive missing-export errors. Export the component Props types from their Flow sidecars and re-export all five types from index.js.flow.

Treat an omitted selectedValue as unselected.

selectedValue is optional, but the current check treats undefined as selected and forwards [undefined] to BaseSelectField. The base field then skips the placeholder path and renders no matching option. Use a nullish check:

Find the default index in newSelectedValues before splicing. newSelectedValues follows selectedValues, not options. If defaultValue is at index 2 in options and is selected alone, selecting another option makes splice(2, 1) a no-op, so the default remains selected with that option.

153-158: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Keep activeItemIndex relative to getFilteredOptions().

updateSearchText and handleKeyDown use indices from options, but selectSingleOption, selectMultiOption, and renderSelectOptions use getFilteredOptions(). For example, searching [No match, Video, Video 2] sets index 1, so Enter selects Video 2 instead of Video. If the raw index exceeds the filtered length, getFilteredOptions()[index] is undefined and item.value throws. Compute the search match with the new search text and derive keyboard bounds from the same filtered list.

- Around line 408-411: Update the default-option removal logic in the
hasDefaultValue branch to find defaultValue’s index in newSelectedValues, which
is derived from selectedValues, rather than in options. Use that selected-values
index for the splice so the default is removed when another option is selected,
including when its options index differs.
- Around line 153-158: Update updateSearchText and handleKeyDown to keep
activeItemIndex relative to getFilteredOptions(), not the unfiltered options
array. Compute the search match using the new search text against the filtered
options, and derive keyboard bounds from that same filtered list so selection
and rendering target the correct item without undefined access.

In `@src/components/select-field/SingleSelectField.tsx`:
- Around line 63-64: Update the selected-value check in SingleSelectField so
both null and undefined selectedValue values are treated as unselected, ensuring
selectFieldProps.selectedValues receives an empty array when omitted and only
forwards a value when present.

Preserve falsy single-select values

SelectOptionValueProp permits numeric and string values, including 0 and ''. In single-select mode, value || null converts either value to null, so SingleSelectField renders no selected option. Use selectedValue={value ?? null}. Valid multi-select values are arrays, so [0] and [''] already survive value || [].

In `@src/components/select-field/SelectField.tsx` at line 57, Update
SingleSelectField’s selectedValue assignment to use nullish fallback instead of
a truthiness check, preserving valid falsy values such as 0 and ''. Leave
multi-select fallback behavior unchanged because arrays already remain truthy.
