Installation

npx payload-components add comparator-stack

What it installs

Copies 3 source files into your project:

src/blocks/shared/comparatorFields.tsshared
src/blocks/ComparatorStack/config.ts
src/blocks/ComparatorStack/Component.tsx

…and makes 4 edits to wire the block into your project:

Registers the block	`src/collections/Pages/index.ts`
Maps the renderer	`src/blocks/RenderBlocks.tsx`
Regenerates types	`src/payload-types.ts`
Regenerates the admin import map	`src/app/(payload)/admin/importMap.js`

Registers the blocksrc/collections/Pages/index.ts

Maps the renderersrc/blocks/RenderBlocks.tsx

Regenerates typessrc/payload-types.ts

Regenerates the admin import mapsrc/app/(payload)/admin/importMap.js

comparatorFields.ts is the shared field core for this family — every variant composes it. Editing it updates each installed block at once, and re-running an install never overwrites a copy you have changed.

Re-running the install converges: it detects existing wiring, skips it, and records install state in .payload-components/state.json.

Content model

title and description come from the shared Comparator family base (src/blocks/shared/comparatorFields.ts); the plans stack is specific to this variant. Unlike the table and grid variants, each plan carries its own features checklist rather than sharing one matrix — good for mobile-first, plan-centric pages.

Usage

Add the block to a page. In the Payload admin, open (or create) a Page and add the ComparatorStack block to its layout.

Fill the content. Complete the fields from the content model above — the component ships sample content you can start from.

Publish. Save and publish the page; the block renders through RenderBlocks on the frontend, fully typed — no extra wiring.

Requirements

Target: payload-website-starter
Payload: v3
Next.js: 15 / 16
shadcn UI: badge, card

Your project must already expose components.json, src/payload.config.ts, src/blocks/RenderBlocks.tsx, src/collections/Pages/index.ts — the surfaces payload-components add patches. The CLI verifies this against the support matrix before touching anything.

In this family

comparator-grid

Comparator GridA plan-column comparison card: pricing columns over a feature matrix, with a highlighted column and per-plan CTAs.

comparator-table

Comparator TableA tiered feature-comparison table: plan columns with CTAs over grouped feature rows of checkmarks or text values.

comparator-stackcurrent

Comparator StackA stacked plan-card comparison: one card per plan with its own price, CTA, and feature checklist.
