Luna theme — key capabilities

Modern UI/UX

Contemporary card-based layout with elevated content blocks, configurable heroes, homepage tiles (flat, gradient, glass, elevated), and consistent styling across KB, community, search, and service pages.

✔ Four brand-ready color palettes

Switch the entire Help Center in one click—Ocean, Verdant, Ember, and Sand—from Global colors in the theme editor. Custom mode keeps your manual color picks.

✔ Structured admin settings (12 sections)

Logo, colors, typography, header, homepage hero, homepage tiles, community tiles, footer, images & banners, search, KB sidebar, and display toggles—labels translated in 37 locales, displayed in each administrator’s Zendesk interface language (agent profile setting—not the visitor’s Help Center locale or OS language).

✔ Knowledge base sidebar

Persistent category tree on KB pages with expand/collapse navigation, active-state highlighting, optional soft navigation, mobile drawer, skeleton loading, and client-side caching.

✔ Advanced search results

Date range filters, hierarchical category filter with hit counts, sort control, live results count, category-column browsing, and support for Zendesk generative answers.

✔ Redesigned KB pages

Unified layout for categories, sections, and articles—subsection icon cards, scoped in-page search, breadcrumbs, and card-style content panels.

✔ Article print to PDF

One-click Print button (toggleable) exports a clean PDF with title, metadata, body, and attachments only—no site chrome, A4-ready pagination.

✔ Community & service catalog

Community topic grids with independent tile styling; branded service catalog landing page with custom hero image when Service Catalog is enabled on your plan.

Built for modern Zendesk & AI-ready experiences

✔ Generative answers compatible

Search results template supports Zendesk generative answers alongside Luna’s enhanced filtering and browsing tools.

✔ Structured knowledge architecture

Semantic article layout, breadcrumb navigation, and hierarchical sidebar help users—and retrieval systems—locate content by section, not just keyword.

✔ Multilingual by design

37 translation files for theme setting labels (matched to each agent’s Zendesk UI language); frontend i18n for Luna-specific UI (sidebar, search, print, section headings). Partial RTL support (Arabic and Hebrew locales included).

✔ Performance-minded

No third-party CDN for Luna custom assets; KB sidebar tree cached locally; search module respects API pagination; CSS design tokens generated from theme settings.

✔ API v4 & full Guide coverage

Templates for home, category, section, article, search, community, requests, approvals, user profile, errors, and service catalog (list + detail).
