+# Management Modal Patterns
+
+Use this guide for modals that manage scoped lists of app-owned records, such as store items now and store zones or locations later.
+
+## Purpose
+- Management modals should keep users in the current workflow while they inspect, edit, add, or remove records for a scoped parent.
+- The parent scope must be obvious in the title, for example `Costco Items`.
+- Modals should avoid repeating table labels inside every row. Use row layout, grouping, and the edit surface for detail.
+
+## Structure
+- Header: title, one short description when the scope is not obvious, and a close button.
+- Primary toolbar: search input plus the primary create action inline.
+- Bulk toolbar: destructive or multi-select actions above the list, separate from search/create controls.
+- List: compact rows with the record's primary identity and any essential visual affordance.
+- Editor: clicking or tapping a row opens the edit/settings modal for that record.
+- Confirmation: destructive actions must use `ConfirmSlideModal`, not browser dialogs.
+
+## Row Behavior
+- Normal mode: the entire row opens settings for that record.
+- Delete mode: the row toggles selected/unselected state and does not open settings.
+- Selection state must be visible on the row and must not rely only on color.
+- Avoid per-row action buttons when the same action applies to every row.
+
+## Bulk Delete Pattern
+- Show a `Delete Items` button above the list for users with delete permission.
+- Clicking `Delete Items` enters delete mode, clears any previous selection, and changes the button to `Confirm Delete (# selected)`.
+- Show a `Cancel` button while delete mode is active.
+- Disable confirm while zero items are selected.
+- Clicking confirm opens `ConfirmSlideModal`; only the slide confirmation performs the mutation.
+- On success, exit delete mode, clear selection, refresh the list, and show a toast.
+- On failure, keep the modal open and show a toast with the API error summary.
+
+## Permission Rules
+- Keep authorization server-side. Client visibility only improves UX.
+- Members can open item settings when the API allows them to manage item details.
+- Delete controls should be shown only to owners/admins when deletion is admin-scoped.
+
+## Accessibility
+- Modal containers should use dialog semantics when practical.
+- Rows that perform actions should be keyboard reachable.
+- Delete-mode rows should expose selected state with `aria-pressed` or an equivalent state.
+- Buttons must have stable labels that describe the action in the current mode.
