# Feature: Email thread members visibility
For this feature we implemented a chip and a dropdown menu that allows
users to check which workspace members can see an email thread, as
depicted on issue (#4199).
## Implementations
- create a new database table (messageThreadMember)
- relations between `messageThreadMembers` and the relevant existing
tables (`MessageThread` and `WorkspaceMembers`)
- added a new column to the `MessageThread table`: `everyone` - to
indicate that all workspace members can see the email thread
- create a new repository for the new table, including new queries
- edit the queries so that the new fields could be fetched from the
frontend
- created a component `MultiChip`, that shows a group of user avatars,
instead of just one
- created a component, `ShareDropdownMenu`, that shows up once the
`EmailThreadMembersChip` is clicked. On this menu you can see which
workspace members can view the email thread.
## Screenshots
Here are some screenshots of the frontend components that were created:

Chip with just one member of the workspace (the owner) being part of the
message thread:

## Testing and Mock data
We also added mock data (TypeORM seeds), focusing on adding mock data
related to message thread members.
## Conclusion
As some of the changes that we needed to do, regarding the change of
visibility of the message thread, were not covered by the existing
documentation, we were told to open a PR and ask for feedback on this
part of the implementation. Right now, our implementation is focused on
displaying who is part of an email thread.
Feel free to let us know which steps we should follow next :)
