Alright, let's start by designing the basic elements that you'll be reusing throughout your project. Think of these as your building blocks. For instance, you might want to create a button component with different states like default, hover, active, and disabled.

Next up, let's define multiple states or styles for these base components. You can do this by creating variants. Just select your base component and head over to the "Variants" section in the right-hand properties panel. Variants are super handy for managing and switching between different styles of the same component.

Now, let's get a bit more creative. Use your base component within another component to create a nested component. For example, if you have a card component, you can use the button base component within it. This way, you can use the button’s different variants within the card component without duplicating the button's code or design. Pretty neat, right?

Time to add some personal touches! Customize the nested components as needed. You can change text, colors, or icons while keeping the primary structure and functionality of the base component intact. This flexibility ensures that all instances of the component stay consistent and can be updated globally.

Organization is key. Keep your components neatly arranged in the Assets panel. Use clear naming conventions and organize components in a hierarchical structure. This makes it easier to access and understand the nested structure.

Here's the magic part. Any changes made to the base component will automatically update all nested components. For example, if you change the primary button’s color, all instances of this button, even if nested within other components, will update instantly. It's like a ripple effect!

Let's make sure everything works smoothly. Test how the nested components interact within complex designs. Use Figma’s prototyping features to define interactions and behaviors between components. Ensure that the interactions work seamlessly and that changes reflect properly across the nested hierarchy.

Take advantage of Figma's Auto Layout feature to dynamically adjust the size and alignment of your nested components. This is especially useful for responsive designs and can ensure that nested components adapt their layout automatically based on the content or screen size.

Finally, document the structure and usage of your nested components within Figma files. This helps collaborators understand the hierarchy and how to effectively use and modify the components. You can share this documentation directly within Figma or as an external guide.
