## What kind of change does this PR introduce? Bug fix and shared UI primitive. ## What is the current behaviour? In **Database > Replication > Add destination**, the searchable **Publication** field uses a double chevron and button styling. It looks inconsistent beside the **Initial sync** select, which uses a single chevron and the standard select surface. The shared multi-select trigger uses the same inconsistent double chevron. These differences are easy to repeat because searchable comboboxes do not have a dedicated trigger that shares the select styling. ## What is the new behaviour? - Adds `ComboboxTrigger` with the same shared styling as `SelectTrigger` - Uses a fixed single down chevron so combobox and select triggers cannot drift - Migrates the Studio **Database > Replication > Add destination > Publication** field to `ComboboxTrigger` - Updates `MultiSelectorTrigger` to replace `ChevronsUpDown` with the same fixed `ChevronDown`, including **Connect > MCP > Feature groups** in Studio - Updates the canonical design-system combobox examples - Leaves `Button` unchanged, so adopting combobox styling is explicit | Before | After | | --- | --- | | <img width="1256" height="448" alt="CleanShot 2026-09-09 at 10 21 32@2x" src="https://github.com/user-attachments/assets/bb7a6056-0b4e-4cb4-8dce-e92fa4f5afe7" /> | <img width="1256" height="448" alt="CleanShot 2026-09-09 at 10 21 11@2x" src="https://github.com/user-attachments/assets/860a06b9-617d-4d94-ac98-944316e9fdc3" /> | | <img width="1210" height="520" alt="CleanShot 2026-09-09 at 10 58 28@2x" src="https://github.com/user-attachments/assets/e916d3a2-6a75-40eb-965a-56e0694ba447" /> | <img width="1210" height="520" alt="CleanShot 2026-09-09 at 10 57 57@2x" src="https://github.com/user-attachments/assets/c5f1b8ff-8083-47b8-8242-59116d085c00" /> | ## Left for incremental migration These existing Studio comboboxes still use bespoke button triggers and will move to `ComboboxTrigger` in focused follow-up changes: - **Database > Backups > Point in time > Timezone** - **Authentication > Third-party auth > AWS region** - **Account > Preferences > Timezone** - Shared schema and function selectors See https://github.com/supabase/supabase/pull/50157. The organisation and project switchers in the top navigation are intentionally out of scope. They are context switchers rather than form-field comboboxes. ## To test ### Studio callsites On the [Studio preview](https://studio-staging-git-dnywh-featcombobox-trigger-supabase.vercel.app): 1. Open **Database > Replication > Add destination**. 2. Compare **Publication** with **Initial sync**. Both should use a single down chevron and the same closed-field surface, border, sizing, and hover treatment. 3. Open **Publication**, search for an option, and select it. The popover should close and the selected publication should be shown. 4. Open **Connect** from the project header, select **MCP**, and check **Feature groups**. Its multi-select trigger should use a single down chevron. ### Design system 1. Check the [combobox examples](https://design-system-git-dnywh-featcombobox-trigger-supabase.vercel.app/design-system/docs/components/combobox). 2. Check the [multi-select examples](https://design-system-git-dnywh-featcombobox-trigger-supabase.vercel.app/design-system/docs/fragments/multi-select). 3. Both trigger types should use a single down chevron.
Supabase Studio
A dashboard for managing your self-hosted Supabase project, and used on our hosted platform. Built with:
What's included
Studio is designed to work with existing deployments - either the local hosted, docker setup, or our CLI. It is not intended for managing the deployment and administration of projects - that's out of scope.
As such, the features exposed on Studio for existing deployments are limited to those which manage your database:
- Table & SQL editors
- Saved queries are unavailable
- Database management
- Policies, roles, extensions, replication
- API documentation
Managing Project Settings
Project settings are managed outside of the Dashboard. If you use docker compose, you should manage the settings in your docker-compose file. If you're deploying Supabase to your own cloud, you should store your secrets and env vars in a vault or secrets manager.
How to contribute?
- Branch from
masterand name your branches with the following structure{type}/{branch_name}- Type:
chore | fix | feature - The branch name is arbitrary — just make sure it summarizes the work.
- Type:
- When you send a PR to
master, it will automatically tag members of the frontend team for review. - Review the main contributing guide to help test your feature before sending a PR.
- The Dashboard is under active development. You should run
git pullfrequently to make sure you're up to date.
Developer Quickstart
Note
Supabase internal use: To develop on Studio locally with the backend services, see the instructions in the internal
infrastructurerepo.
# You'll need to be on Node v22
# in /studio
## For external contributors
pnpm install # install dependencies
pnpm run dev # start dev server
## For internal contributors
## First clone the private supabase/platform repo and follow instructions for setting up mise
mise studio # Run from supabase/platform alongside `mise infra`
## For all
pnpm run test # run tests
pnpm run test -- --watch # run tests in watch mode
Running within a self-hosted environment
Follow the self-hosting guide to get started.
cd ..
cd docker
docker compose -f docker-compose.yml -f ./dev/docker-compose.dev.yml up
Once you've got that set up, update .env in the studio folder with the corresponding values.
POSTGRES_PASSWORD=
SUPABASE_ANON_KEY=
SUPABASE_SERVICE_KEY=
Then run the following commands to install dependencies and start the dashboard.
npm install
npm run dev
If you would like to configure different defaults for "Default Organization" and "Default Project", you will need to update the .env in the studio folder with the corresponding values.
DEFAULT_ORGANIZATION_NAME=
DEFAULT_PROJECT_NAME=
