How to Supercharge your Design System with Slots | Figma Blog (opens in new tab)
Slots let designers customize components without detaching them from a design system. By allowing content to be inserted into stable structures—much like components work in code—slots reduce variant sprawl, preserve consistency, and improve design-to-development handoff. Figma recommends starting with high-traffic components and using default content strategically to balance guidance with flexibility. ## Why Slots Matter - Growing design systems often become restrictive, leading teams to: - Create excessive variants - Expand component libraries - Detach instances - Develop workarounds outside the system - Slots allow designers to change content while preserving a component’s underlying structure. - The approach mirrors code-based composition, where developers inject dynamic content into predictable layouts. - Benefits include: - **Design system managers:** fewer variants and less maintenance - **Designers:** more freedom within the system - **Developers:** structures that map more predictably to production - **Automation and AI:** clearer, more interpretable component structures - Figma introduced slots at Schema 2025 and made them available in open beta. ## Start with High-Use Components The greatest immediate value comes from components that teams frequently detach or customize. - Prioritize components that: - Appear often across screens - Are duplicated throughout the system - Have accumulated many variants - Support frequently changing content - Common starting points include: - Dialogs and modals - Menus and lists - Cards and panels - Slots are especially useful when the structure stays stable but the content varies. - Repeating elements such as menu items or list rows no longer require numerous hidden layers for every possible item count. - Designers can add only the items they need while keeping the component connected. - For configuration-heavy components like cards and modals, slots can replace combinations of properties and variants for titles, descriptions, media, and buttons. ## Use Pre-filled and Empty Slots Deliberately Slots can either contain default content or remain empty, depending on the intended workflow. - **Pre-filled slots:** - Provide context and demonstrate expected usage. - Reduce unnecessary work when content is usually predictable. - Are useful for persistent elements, such as an icon in the top-right corner of a card. - **Empty slots:** - Clearly signal that the designer must add content. - Work well when customization is required. - Resemble existing instance-swap patterns used in many design systems. - Authors should choose between the two based on whether content is optional, predictable, or required. Figma’s practical recommendation is to introduce slots where teams already experience the most friction, then use defaults and empty placeholders intentionally to guide customization without sacrificing flexibility.
