Component properties in Figma enable the creation of customizable elements within components, making it easier to reuse and adapt designs across projects. There are three main types of component properties:

1. Instance Swap Property

This property allows you to swap nested components, such as icons, within the main component. Pre-selected icons or values can be added for easy customization.

To create this property:

• Select the instances you want to swap.

• Use the Create Instance Swap Property option from the Design panel.

2. Boolean Property

The Boolean property enables toggling elements on or off, like showing or hiding icons or text.
For example, a property named "Has Left Icon?" can control the visibility of an icon on the left side of a button. This property is added under the Appearance section.

3. Text Property

The Text property allows you to change text within a component directly from the Design panel.

To create this property:

• Select the text element.

• Use the Apply Property or Variant icon in the top-right corner of the Design panel to create the property.

These properties can be reordered in the Design panel for better organization. Changes made to the properties, such as toggling a Boolean property, automatically adjust other related properties for seamless functionality. Testing all properties by creating an instance of the component ensures adaptability for future projects.

Component properties greatly improve efficiency in building and managing reusable components, such as button libraries, saving time and ensuring design consistency.
