Key Value Input

sanity-key-value-input

Sanity Studio input component for editing ordered key-value string pairs. Supports add, remove, and reorder operations with real-time patch updates.

Use it in place of Sanity's default array-of-objects editor when you want a compact, spreadsheet-style row layout — both fields visible inline, with explicit up/down reordering — for metadata, attributes, or any ordered list of key → value strings.

Preview

Empty / initial state — a single placeholder row with the Add Row button below.

With entries — once rows exist, the reorder rail appears on the left and a trash icon on the right of each row.

Install

npm install @liiift-studio/sanity-key-value-input

Usage

Use KeyValueInput as a custom input component on an array field. The array items must be objects with two string fields named exactly key and value — the component reads and writes those field names directly.

import { defineType, defineField } from 'sanity'
import { KeyValueInput } from '@liiift-studio/sanity-key-value-input'

export const mySchema = defineType({
	name: 'myDocument',
	type: 'document',
	fields: [
		defineField({
			name: 'metadata',
			title: 'Metadata',
			type: 'array',
			of: [
				{
					type: 'object',
					fields: [
						{ name: 'key', type: 'string' },
						{ name: 'value', type: 'string' },
					],
				},
			],
			components: {
				input: KeyValueInput,
			},
		}),
	],
})

The component provides:

• Add new key-value pairs
• Remove existing pairs
• Reorder pairs up and down
• Inline editing of both key and value fields

Data shape & querying

Each row is persisted as an object with an auto-generated _key plus the key and value strings. The component manages _key for you (you do not need to set it), so the stored field is an ordered array of:

flowchart LR
	A["metadata (array)"] --> B["{ _key, key, value }"]
	A --> C["{ _key, key, value }"]
	A --> D["…"]
	subgraph item["one row"]
		B1["_key: string  (auto-generated)"]
		B2["key: string   (your label)"]
		B3["value: string (your value)"]
	end
	B -.-> item

A stored document field looks like:

"metadata": [
	{ "_key": "a1b2c3d4e", "key": "Engineer", "value": "Name" },
	{ "_key": "f5g6h7i8j", "key": "Edition",  "value": "2024" }
]

Read the pairs back with GROQ — array order is preserved:

*[_type == "myDocument"]{
	"metadata": metadata[]{ key, value }
}

Styling (optional)

The reorder and remove controls render as functional buttons out of the box. For finer visual control they expose styling hooks via the class names manualButton, manualButtonUp, manualButtonDown, and manualButtonWrap. The package does not ship CSS for these — add your own rules in the consuming Studio if you want to customise their appearance. Reorder and remove work whether or not you style them.

Requirements

• Sanity Studio v3+ (uses set() patches and the array field components.input API).
• The peer dependencies below, installed in the consuming Studio.
