Overview
This lets you modify how components are structured and rendered in your app. You can:- Replace default HTML with your own components and HTML structure
- Remove or reorder components
- Create multiple variants of the same component
All layout customizations are done using Wireframe components that act as templates. Changes apply globally wherever that component is used.
Ways to Customize Layout
Single Component Customization (Targeted)
This lets you customize individual parts of a component without dealing with the entire structure. We recommend this approach for most use cases. Benefits:- Simpler, more maintainable code
- Focus on just the parts you need to change
- Greater flexibility for specific UI elements
- React / Next.js
- Other Frameworks
Full Component Tree Customization (Comprehensive)
Use this pattern when you need to modify the entire component structure or multiple related components. Benefits:- Complete control over component hierarchy
- Easier to modify relationships between components
- Better for large-scale structural changes
- Custom CSS required for the entire component tree since adding children components to wireframes removes Velt’s default styles.
- React / Next.js
- Other Frameworks
Variants
Variants allow you to:- Create multiple styled versions of the same component
- Switch between them dynamically in different parts of your app
- Maintain consistent behavior while having different looks
Create Custom Variants
Custom variants let you define your own versions of components. For example: You can have a variant of Comment Sidebar for one page and another for another page.1
Define variants
On the wireframe component, add the
variant prop to define your custom variants.- React / Next.js
- Other Frameworks

Use variants
- Use the
variantprop on the related Velt component to apply the custom variant you defined. The value should match the variant name from step 1. - For example, use
variant="preview-page"to apply the preview page variant you created above.
- React / Next.js
- Other Frameworks
Use Pre-defined Variants
Many components come with built-in variants optimized for specific use cases. For example, the Comment Dialog has two pre-defined variants for different contexts:- React / Next.js
- Other Frameworks
- Each component’s documentation lists its supported pre-defined variants
- Pre-defined variants are optimized for specific use cases but can still be customized
- You can combine pre-defined variants with your own custom styling
Common Customization Tasks
Replace Default Layout
Simply provide your own HTML or components as children of the wireframe component:- React / Next.js
- Other Frameworks
Remove Components
To remove a component, you either:- simply omit it from the wireframe template as shown below, or
- use Conditional Templates
- React / Next.js
- Other Frameworks
Reorder Components
To reorder components, simply rearrange them within the wireframe template.- React / Next.js
- Other Frameworks
