# Customize theme components

You can customize theme components instead of ejecting them completely.

Customizing components can be useful in several scenarios:

- When developing custom components by reusing existing `theme` functionality, rather than building from scratch.
This is particularly effective when integrating into more complex components.
- When extending or modifying the styles of existing components, especially in cases where the default theme `variables` are insufficient.


Find a list of available components with their properties in the [components list](/docs/realm/customization/react-components/list) and a full list of supported icons in the [icons list](/docs/realm/customization/react-components/list/icons).
