Plone Badisblocks

Server-side rendering of Volto/Seven blocks in Plone Classic UI ("Badis UI") with Chameleon page templates — no frontend build step. Block-enabled content is rendered through BrowserViews that dispatch by block @type to per-type @@block-<type> views.

See docs/blocks-renderer-spec.md for the architecture.

Features

• Compatible with Plone 6.2+
• Renders block content (volto.blocks behavior) without a REST round-trip
• Block renderers: title, description, slate (rich text), image, gridBlock (nested), teaser, listing, introduction, html, slateTable, toc, video, maps, plus a default fallback
• Slate rich-text serializer with tag whitelisting (no unsanitized editor HTML reaches the page)
