The visual editor

Design Semantic UI screens visually — entirely in the browser, no backend, no install. The editor is a fully client-side app: projects and pages live in localStorage, you edit and preview live, and export a runnable app when you're done.

▶ Open the visual editor ↗ — runs in your browser, nothing to set up.

It's embedded right here — this is the real editor, not a screenshot. Pick a project, click a node in the tree, edit its JSON, watch the preview update:

More room

The editor is a full three-panel app — it's much nicer full-screen ↗.

What it is

Three resizable panels, all driven by the same SuiRenderer as production (which is why it was small to build — the UI model and the renderer are separate):

• Tree — outline of the UiNode tree, with add (+) and delete (×).
• Property panel — a Monaco JSON editor for the selected node with live schema validation generated from the real UiNode classes (wrong enum values, type mismatches and unknown node types are underlined inline); edits apply on blur or Ctrl/Cmd-Enter.
• Live preview — the actual tree rendered through the SUI renderer. Clicks on any rendered element select the corresponding tree node; selecting a tab switches the preview into that tab.

Download a runnable app

This is the part people miss: the editor doesn't just draw mock-ups — it exports a working application you can download and run. Pick a target and you get a complete project:

Export	What you get	Run it with
Static	index.html + app.js + the sui/ runtime — no backend	open the file, or any static file server
Spring Boot	a Maven project with a controller per page returning UiPage	mvn spring-boot:run
Node.js	an Express server serving each page as UiPage JSON	npm install && npm start

The output is plain, hand-written semantic-ui code — not a bundled copy of the editor, and with no dependency back on it. So it's a real starting point: design the screens visually, export, then keep building in your IDE.

It's also the fastest way to scaffold any of the three setups.

Embed it in your own app (optional)

The same editor is also an embeddable Spring Boot starter — add the dependency, provide an EditorContentStore, and /editor is live inside your app:

<dependency>
  <groupId>ai.mindconnect</groupId>
  <artifactId>mc-sui-editor</artifactId>
  <version>0.4.3</version>
</dependency>

A standalone showcase lives in editor/mc-sui-editor-app:

cd editor/mc-sui-editor-app
mvn spring-boot:run
# then open http://localhost:8080/editor

Its sample content exercises every node type (header, tabs, a table with a SKU-link cell template, a form with various field kinds, multi-select rows, …) — a good orientation when you first embed the editor.
