# UnifiedWriter dev-5.46.3 File Menu Submenu Fix

This build fixes the File menu Import / Export submenu behavior.

## Root cause

The root dropdown menu had `overflow-y:auto` for long menu regression checks. In CSS, a vertical scroll container also creates horizontal clipping behavior for absolutely positioned child submenus. As a result, Import / Export showed a right arrow but the child menu was clipped and a horizontal scrollbar appeared.

## Fix

- Keep nested menu panels as visible popouts instead of scroll-contained children.
- Preserve click and hover behavior for submenu parent rows.
- Keep actual Import / Export commands on child rows so they still flow through the CommandBus and Host callback policy.
- Keep `showFileProperties` using the runtime `escapeHtml` helper added in v5.46.2.

## Policy

Import / Export / Save As do not expose storage-provider submenus inside UnifiedWriter. Host OpenFile / SaveFile / Export callbacks or Host-side adapters remain responsible for choosing Local Device, App Storage, Google Drive, Backend API, WebDAV, etc.
