What is Full Site Editing (FSE) in WordPress and how is it related to Kadence?
Full Site Editing (FSE) has completely revolutionized the way we design and manage WordPress websites. If you’re looking to master this transformative technology and get the most out of Kadence in this new ecosystem, you’ve come to the right place.
What is Full Site Editing and Why Should You Care?
Full Site Editing isn’t just another WordPress update it’s the most significant revolution since the introduction of the Gutenberg editor. This functionality, which reached maturity with WordPress 5.9 in January 2022, allows you to visually edit every aspect of your website using a block based approach.
Many designers are still clinging to outdated methods while their competitors are already leveraging the advantages of FSE to build faster, more flexible, and easier to maintain sites.
Core Components of FSE
FSE is built on four essential pillars that revolutionize the design experience:
Site Editor: A unified interface under Appearance → Editor that lets you visually edit templates and template parts.
Templates and Template Parts: Design structures for specific content types and reusable sections like headers and footers.
Global Styles: Centralized controls for typography, colors, and layout that apply across the entire site.
Block Themes: Themes built entirely with blocks, which are necessary to fully utilize FSE features.
FSE vs. The Classic Editor: A Night and Day Difference
The contrast between the Classic Editor and FSE represents a paradigm shift in web development:
Classic Editor: Limited to an interface similar to Microsoft Word with basic formatting functions and total reliance on the theme for design modifications.
FSE: A modern, block based interface with intuitive controls that allows for complete visual editing of the entire website, granting total creative freedom without theme restrictions.
But here’s where it gets interesting: FSE not only improves the editing experience but also democratizes web design by allowing users without advanced technical skills to create professional sites.
The Unstoppable Evolution of FSE in WordPress

The development of FSE has been a gradual but steady process that began with the Gutenberg project and has evolved significantly to become the WordPress standard.
WordPress 5.9: The Historic Turning Point
WordPress 5.9 “Josephine,” released in January 2022, marked the MVP (Minimum Viable Product) of Gutenberg’s customization phase. This version introduced revolutionary elements that changed the WordPress landscape forever:
- Block Themes: Themes based entirely on blocks
- Site Editor: A unified interface for complete site editing
- Global Styles: A visual configuration system
- Editable Templates: Customization of page layouts
- theme.json file: Programmatic configuration of styles
WordPress 6.8: The Definitive Consolidation
WordPress 6.8, released in April 2025, consolidated FSE functionalities with significant improvements in usability and performance. The most notable enhancements include:
Improved Editor:
- Integrated template selector with direct access from the preview menu
- Optimized data views for more organized page and template management
- Simplified navigation with a more intuitive workflow
Revamped Style Book:
- More structured layout with clear labels
- Direct access from the editor’s sidebar menu
- Consolidated editing for colors, typography, and block styles
Performance Enhancements:
- Speculative Loading: Faster navigation that preloads pages in the background
- bcrypt for passwords: Enhanced security
- Code optimizations for better overall performance
Current Trends in Modular Design
Modular design has established itself as a dominant trend, and FSE is perfectly aligned with this philosophy. The features of modular design in FSE include:
Reusable Components:
- Reusable pre designed block patterns
- Flexible and adaptable modular templates
- Custom blocks for various specific needs
- Design systems that ensure visual consistency
Dynamic and modular content allows administrators to create content that updates automatically based on user behavior, maximizing engagement and relevance.
Kadence and its Strategic Position in the FSE Ecosystem
What Makes the Kadence Theme Special?
Kadence Theme is a lightweight yet feature rich WordPress theme designed for building fast, accessible, and visually stunning websites. With over 400,000 active installations and a 5 star rating, it has established itself as one of the most popular alternatives on the market.
Distinctive Features of Kadence:

The Current State of Kadence with FSE
The reality is: Currently, Kadence Theme is not a native FSE theme but a classic/hybrid theme that offers advanced customization features through its own system. However, Kadence WP has confirmed the development of an FSE version of the theme.
As the Kadence team officially stated: “Will Kadence Theme support WordPress core’s block-based, full-site editing? Yes! We are working on a version of the Kadence Theme which will support FSE”.
Kadence Blocks: The Bridge to FSE
Kadence Blocks is the companion plugin that extends Gutenberg’s capabilities with advanced blocks designed for creating professional websites. This plugin is crucial because it works in both classic and FSE themes.
Essential Blocks Included:
Content Blocks:
- Accordion: Expandable sections with nested content
- Advanced Button: Customizable buttons with hover effects
- Advanced Text: Complete typography control
- Icons: Over 1,500 SVG icons included.
Layout Blocks:
- Row/Layout: Flexible column system
- Spacer/Divider: Spacing and separator control
- Testimonials: Stylized review sections
- Advanced Gallery: Responsive carousels and sliders
The result was stunning: Kadence Blocks only loads CSS or JavaScript when needed and only for the blocks being used on a specific page, significantly optimizing performance.
How to Implement Kadence with FSE: A Practical Strategy
Step 1: Initial Ecosystem Setup
To leverage Kadence in an FSE environment, you need to correctly set up both the theme and its companion plugins:
Installing the Kadence Ecosystem:
- WordPress Admin → Themes → Add New → Search for “Kadence”
- WordPress Admin → Plugins → Add New → “Kadence Blocks”
- WordPress Admin → Plugins → Add New → “Kadence Starter Templates”
Activating a Compatible FSE Theme:
- Twenty Twenty-Four: Recommended native FSE theme
- Other FSE themes: That support Kadence Blocks
- FSE Check: Verify that “Editor” appears under Appearance
Step 2: Optimizing Kadence Blocks for FSE
Critical Settings:
| Setting | Recommendation | Purpose |
|---|---|---|
| Required Blocks | Activate only those needed | Performance optimization |
| CSS Loading | Optimized mode | Reduce page weight |
| Global Settings | Establish defaults | Design consistency |
| Responsive settings | Configure breakpoints | Adaptive design |
Disabling unnecessary blocks can reduce resource load by up to 40%, significantly improving loading speed.
Step 3: Creating Advanced Global Templates
Creating global templates by leveraging Kadence Blocks in an FSE environment allows you to design reusable and consistent layouts:
Recommended Template Structure:
text- Header with Kadence Blocks: Logo, navigation, and custom elements
├── Advanced Header Block
├── Advanced Navigation Block
└── Logo and custom elements
- Content Area: Kadence Blocks for specific sections
├── Row/Layout Blocks
├── Advanced Text Blocks
└── Custom Button Blocks
- Custom Footer: Contact info, social links
├── Advanced Footer Elements
├── Social Media Integration
└── Copyright and secondary navigation
Step 4: Professional Headers and Footers
Kadence offers two powerful methods for customizing headers and footers in FSE environments:
Method 1: Kadence Native Builder (Classic Theme)
- 3 header rows: Top, main, and bottom
- 3 sections per row: Left, center, right
- Available elements: Logo, navigation, buttons, search, cart, social.
Method 2: Advanced Header/Footer Blocks for FSE
