## Summary Closes #20139. In a workflow **Create / Update / Upsert Record** action, the field input for a `SELECT` field always offered a **"No value"** option. Selecting it clears the field — even when that field is **not nullable** (for example an opportunity `Stage`). The maintainer asked in the issue to *"not allow to put a 'No stage' if the field is not nullable"*. ### Root cause `FormSelectFieldInput` unconditionally builds a `defaultEmptyOption` and passes it as the `<Select>`'s `emptyOption`, regardless of the field's nullability: ```tsx const defaultEmptyOption = { label: label ? t`No ${label}` : t`No value`, value: '', icon: IconCircleOff, }; // ... <Select ... emptyOption={defaultEmptyOption} /> ``` The nullability is already available on the field metadata (`FieldSelectMetadata.isNullable`), and the regular (non-workflow) record input already gates its clear affordance on it in `SelectFieldInput.tsx` (`fieldDefinition.metadata.isNullable && canSelectEmpty ? handleClearField : undefined`). The workflow form input just wasn't using it. ### Fix - Add an optional `isNullable` prop to `FormSelectFieldInput` and only build the empty option when the field is nullable (`isNullable !== false`). `emptyOption` is already optional on `<Select>`, so omitting it cleanly removes the choice. - Pass `isNullable={field.metadata?.isNullable}` from `FormFieldInput`'s `isFieldSelect` branch. The prop is optional and defaults to the previous behaviour, so the other `FormSelectFieldInput` call sites (country, calling code, currency, cron, etc.) are unaffected. Scope is intentionally limited to single `SELECT`: `FieldMultiSelectMetadata` has no `isNullable` field and the multi-select input has no equivalent empty option, so it is left untouched. ## Test plan - [x] `npx oxlint --type-aware` — passes on the changed files - [x] `npx oxfmt --check` — passes - [x] `tsc --noEmit` — no type errors in the changed files - [x] Added a `NonNullable` Storybook interaction test asserting the "No value" option is not rendered when `isNullable={false}` - [ ] Manual: in a workflow Update Record step on Opportunity, the **Stage** field no longer shows a "No value" option; a nullable select still does --------- Co-authored-by: Charles Bochet <charles@twenty.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.
