## Summary Fixes #21840 Currently, selecting a root folder in **Settings → Accounts → Emails → Folders** automatically selects all of its subfolders, and selecting a subfolder automatically selects all of its ancestor folders. Users have no granular control over individual folder sync. This PR replaces the cascade selection logic with fully independent per-node selection, matching standard tree-select UX patterns used in file explorers and permission trees. ## Changes ### Bug Fix - **`computeFolderIdsForSyncToggle.ts`**: Removed `collectChildren` and `collectParents` cascade helpers. The function now returns only the toggled folder's ID, enabling fully independent selection. - **`SettingsAccountsMessageFoldersCard.tsx`**: Updated call site to match simplified function signature (removed unused `allFolders` and `isSynced` args). ### Tests - **`computeFolderIdsForSyncToggle.test.ts`**: Rewrote tests to reflect new per-node behavior. Removed tests asserting old cascade behavior; replaced with tests verifying only the toggled folder is affected. - **`isFolderTreePartiallySelected.test.ts`** *(new)*: Added 9 tests for `isFolderTreePartiallySelected`, which is now the primary mechanism driving the indeterminate checkbox state on parent folders. ## Behavior Before / After | Action | Before | After | |--------|--------|-------| | Check a root folder | Checks root + all subfolders | Checks root only | | Check a subfolder | Checks subfolder + all ancestors | Checks subfolder only | | Uncheck a root folder | Unchecks root + all subfolders | Unchecks root only | | Parent with partial children | No indeterminate state (broken) | Shows `–` indeterminate correctly | ## What Was Already Correct The indeterminate checkbox UI was already fully implemented: - `isFolderTreePartiallySelected` correctly detects mixed sync states in subtrees - `SettingsMessageFoldersTreeItem` already passes `indeterminate` to the `Checkbox` component - The `Checkbox` component in `twenty-ui` already supports the `indeterminate` prop Only the toggle cascade logic needed fixing. ## Testing ```bash # Unit tests cd packages/twenty-front && yarn jest --testPathPattern="computeFolderIdsForSyncToggle|isFolderTreePartiallySelected" # Lint npx nx lint:diff-with-main twenty-front # Type check npx nx typecheck twenty-front <!-- This is an auto-generated description by cubic. --> <a href="https://cubic.dev/pr/twentyhq/twenty/pull/21853?utm_source=github" target="_blank" rel="noopener noreferrer" data-no-image-dialog="true"><picture><source media="(prefers-color-scheme: dark)" srcset="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"><source media="(prefers-color-scheme: light)" srcset="https://www.cubic.dev/buttons/review-in-cubic-light.svg"><img alt="Review in cubic" src="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"></picture></a> <!-- End of auto-generated description by cubic. --> --------- Co-authored-by: Charles Bochet <charles@twenty.com> Co-authored-by: neo773 <62795688+neo773@users.noreply.github.com> Co-authored-by: neo773 <neo773@protonmail.com>

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
