Greptile Overview

Greptile Summary

This PR adds @ mention functionality to the BlockNote editor in notes, allowing users to mention and link to any object in the CRM.

Key changes:

• Added MentionInlineContent component that renders mentions as clickable RecordChip elements using useFindOneRecord to fetch record data
• Extended the BlockNote schema to include mention inline content spec
• Implemented useMentionMenu hook that searches across all active, non-system, searchable objects using useObjectRecordSearchRecords
• Created CustomMentionMenu and CustomMentionMenuListItem components following similar patterns to the existing slash menu
• Added click-outside handling to prevent command menu from closing when interacting with the mention dropdown

Architecture notes:

• The search is limited to 50 results (MENTION_SEARCH_LIMIT)
• Mentions are stored with recordId and objectNameSingular, fetching fresh data on render via useFindOneRecord
• Results are filtered to exclude system objects and non-searchable items

Confidence Score: 4/5

• PR is generally safe to merge; the identified race condition may cause brief UI flicker but is not critical.
• Well-structured implementation following existing patterns (CustomSlashMenu). One potential race condition in search results delivery, but the feature will still function correctly after results load.
• useMentionMenu.ts has a potential race condition where search results may briefly show stale data.

Important Files Changed

File Analysis

Filename	Score	Overview
packages/twenty-front/src/modules/ui/input/editor/hooks/useMentionMenu.ts	3/5	New hook for mention menu search. The getMentionItems callback has a potential race condition - it sets state then immediately returns stale items before the search query completes.
packages/twenty-front/src/modules/activities/blocks/components/MentionInlineContent.tsx	4/5	New inline content component for rendering mentions using RecordChip. Fetches record data using useFindOneRecord hook when rendered.
packages/twenty-front/src/modules/ui/input/editor/components/CustomMentionMenu.tsx	4/5	New mention menu dropdown component following similar patterns to CustomSlashMenu. Uses SelectableList and DropdownContent for consistent UI.
packages/twenty-front/src/modules/ui/input/editor/components/BlockEditor.tsx	5/5	Added @ trigger for mention suggestions using new CustomMentionMenu and useMentionMenu hook.
packages/twenty-front/src/modules/activities/blocks/constants/Schema.ts	5/5	Extended BlockNote schema with mention inline content spec for displaying linked mentions.

   logic: Potential race condition: setSearchQuery(query) triggers an async state update, but mentionItems is returned immediately with results from the previous query. On first keystroke, users may see stale/empty results until the next render cycle.

@Bonapara is this useful if it doesn't ping the user? I feel it's too early

[Bonapara]

@charlesBochet I think it’s useful to be able to mention other records in notes, even without notifications, as long as you can mention a team member in v1.

(It seems this PR only allows mentioning records from objects that are:

• Active (isActive: true)
• Not a system object (isSystem: false)
• Searchable (isSearchable: true)
  )

Which seems fine to me.

Thanks a lot for raising this PR @acee3! It will bring a lot of value to Twenty.

Two main pieces of feedback from a product/design perspective:

1. Can you use our relation chip component?

2. A few notes on the menu design:

   
   1. Add top padding.
   2. Add the name of the object as a subtitle.
   3. Set the menu width to 240 px.

@Bonapara Thanks for your response and feedback! I am a little bit confused about what you mean by using the relation chip component. I wasn't able to find one other than the RecordChip, which I was already using. I assumed you meant that the icon of the object should show, so I made some updates to that. If that is the case, I was able to implement all your changes.

Also, I don't think the failing CI front storybook test about network failure seems to be related to the change I just made. Other people seem to be getting the same exact failing test.

[Bonapara]

Hi @acee3, yes indeed!

For the rest, I couldn’t try your PR yet, as it seems you didn’t take permissions into account:

message: "Entity performing the request does not have permission"

[acee3]

@Bonapara @prastoin I fixed the issues with perms. Let me know if there is anything else that needs to be changed/added!

[prastoin]

Hey @charlesBochet could you please re-review this when you have some freetime please ?

[acee3]

@charlesBochet @prastoin @Bonapara Just checking in if there is anything I need to do to get this merged?
