Select

Two field types, not six (AD decision, 2 Sep 2026 — review ACRM-76–81, pick ACRM-105). The four approved dropdown types A–D (Petr, 21 Aug 2026 — docs/PLAN-dropdown-sjednoceni.md in acrm) are two axes — search yes/no × multiple yes/no — so the family has Select (closed list) and Record select (searchable list of records), each with a multiple mode, plus Nav select (context switch in the top bar, different trigger) and Picker menu (action menu, not a field).

Everything else that used to be its own entry is a mode or a usage of those two and is now deprecated: MultiSelect = Select with multiple (1 usage), Combobox = Record select with free text (1 usage), CheckMenu = the multiple mode drawn as a menu (2), RailPickerMenu = Record select anchored in a rail row (2), EntityPicker = Record select with async search (12), ProductPicker = the same limited to products (2). They stay listed until their usages are migrated; nothing new is built on them. Rule that binds the family (docs/DS-USAGE.md): dropdowns are always the DS popover, never a native <select>.

Values measured from apps/web/src/ds.css and apps/web/src/ds/inputs.css on main: shell .acrm-popover (or .acrm-recordselect-pop for search panels) = --surface-100, 1px --border-strong, --radius-md, --shadow-pop, padding --sp-2, z-index 101 over a scrim at 85; row = 500 13px/20px var(--font-sans), padding --sp-2 --sp-3 → 32px, hover --hover-surface; select-one check = .chk in --accent, hidden with visibility; multi = .acrm-checkbox 16px, 1.5px --border-strong, --radius-xs, on the RIGHT; search row = borderless input 400 14px, 18px icon, hairline --border below; list scrolls inside max-height: 264px. Field triggers (.acrm-select-trigger, .acrm-recordselect-trigger, .acrm-combobox) are 32px, --radius-sm, open state = --accent border + 3px accent halo (16%). Top-bar trigger .tchip = --control-h 30px, --radius-md, --shadow-xs, open = --active-surface.

The story Components / Select → Dropdown types shows the four side by side.

Where each picker sits

Consolidation notes

• One shell: AddRefMenu + useAnchoredPanel (EntityPicker, ProductPicker, RecordSearchSelect) and .rcpt-menu (AssignPicker) re-implement what Popover and useAnchoredMenu already do. Plan MR 7 and MR 15 fold them into type B.
• One row: DialCodePicker rows (.phe-ccrow) should become .acrm-popover-item (the code in the name, no trailing tag).
• One check: RecordSelect single should draw .acrm-recordselect-ck like RailPickerMenu — a checkbox promises multi-select (F261).
• Async options on RecordSelect remove the reason for RecordSearchSelect.
• CheckMenu and RailPickerMenu are canonical by anatomy but live app-side; the catalog renders their markup, not the components.
• Zero native selects is the target: ChannelsPopoverEditor type cell is the last one.

Legacy card Inputs — what still holds

Harvested from legacy/Inputs.html ("Výběr & rozbalovací nabídky", "Rozbalovací nabídky") and legacy/popover.html, checked against apps/web/src/ds.css and apps/web/src/ds/inputs.css:

• Still true: "No headings inside menus — never an eyebrow above the items; the only exception is a hairline group separator." "Menu, combobox and popover carry --shadow-pop over a hairline ring and --radius-md." "The active item in a single select carries the check on the right; in a multi select the filled checkbox on the right (D6, 22 Aug 2026)." "Record select opens with a search box on top (hairline), the list scrolls inside 264px; use it whenever the list has more than ~10 items." "The LIST scrolls, not the panel — a scrolling panel with a sticky header produced F257." "One-line items 500 13/20 → 32px; .sub descriptions removed 21 Aug 2026; the trailing .tag removed 28 Sep 2026 (ACRM-375–377) — a row is its name only." "Fields are flat at rest; the shadow belongs to the open menu." Record select variants "single (check, closes on pick) · text-only (no avatar, code lists) · in menu (no trigger, search is the first row) · search without list (hairline disappears)".
• Superseded or ahead of code: the card's Record select "single" check is only implemented app-side (RailPickerMenu); RecordSelect in the package still draws a checkbox in single mode (F261 alignment pending). The card's "text-only" Record select rows have no package prop — RecordSelect always renders an avatar; the text-only row exists in RailPickerMenu (avatar omitted). The card's "Nadpis-dropdown (s ikonou)" is the .pipe-btn screen switch (family Section top bar), not a member of this family. The registry summary "native select on mobile" for Select is not in code — the native element is sr-only form backing on every viewport.

Sub-components

Current

• Select · accessibility — closed list, single or multiple
• Record select · accessibility — searchable records, single or multiple, optional free text
• Nav select · accessibility — context switch in the top bar
• Picker menu · accessibility — menu of actions

Deprecated — listed for migration, never for new work

Migration order (largest first): Entity picker → Product picker → Check menu → Rail picker → Multi-select → Combobox. Each step is a separate merge request; the deprecated entry disappears from the registry once its last usage is gone.
