What changed

• Expand models directly when the desktop selector has a single model family.
• Show family entries and a cascading model submenu when multiple families are available.
• Keep cascading menus on the outward side when the selector flips near the viewport edge.
• Add focused regression coverage and update the Wework task documentation in Chinese and English.

Why

The desktop selector previously flattened every family into one model list. This made models from different providers indistinguishable and did not match the intended progressive menu behavior.

User impact

Small catalogs remain fast to scan, while larger catalogs are organized by family before model selection.

Validation

• pnpm --filter wework exec prettier --check ...
• pnpm --filter wework exec eslint ...
• pnpm --filter wework exec tsc --noEmit
• pnpm --filter wework test (200 files, 1997 tests)
• Isolated real-Tauri verification for single-family expansion, multi-family navigation, cross-family hover switching, and final model selection
• Pre-push Wework ESLint, TypeScript, and unit-test checks

Summary by CodeRabbit

• New Features

  • Improved the desktop model selector with nested model-family menus.
  • When multiple model families are available, select a family to view its models; single-family menus show models directly.
  • Added clearer empty states, model labels, environment indicators, and disabled-model handling.

• Documentation

  • Updated English and Chinese guidance to explain model selector behavior.
  • Reformatted the task-control keyboard shortcut tables for improved readability.

Warning

Review limit reached

@qdaxb, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 20 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The desktop model selector now groups models by family. Single-family menus show models directly, while multi-family menus require choosing a family before displaying its models. State handling, submenu positioning, rendering, tests, and English and Chinese documentation were updated.

Changes

Desktop model selector family navigation

Layer / File(s)	Summary
Selector state, activation, and submenu layout wework/src/components/chat/composer/ModelSelector.tsx	Tracks the active family, resets submenu state, centralizes model submenu activation, and calculates nested submenu placement.
Family and model option rendering wework/src/components/chat/composer/ModelSelector.tsx	Renders model states and nested family-specific model options, including empty, disabled, and cloud model handling.
Behavior coverage and usage guidance wework/src/components/chat/composer/ModelSelector.test.tsx, wework/src/components/chat/ChatInput.test.tsx, docs/en/wework/tasks.md, docs/zh/wework/tasks.md	Tests single- and multi-family expansion behavior and documents the corresponding model selection flows.
Estimated code review effort: 3 (Moderate)	~20 minutes
