An icon is a graphic symbol that represents an object (ie a file) or a function. They can be used to give the user feedback.

Icon Default

Icon Rotate

Icon Flip

Icon Animation



A spinner icon can show a user that something is loading or saving.

Icon Pull

Icon Pull can be used to indicate that the user can perform a pull action.

Icon Border

Icon Sizes














Icon Custom

Custom icons are compatible with other icon props (size, rotation, spin, flip, etc). Their SVG fill colors will be inherited from parent element's css color properties.

Tips for Custom Icons

When using custom icons it is important to introduce a "clean" SVG. In order to ensure these custom icons perform as intended within your kit(s), ensure these things have been modified from the original SVG markup:

Attributes must be React compatible e.g. xmlns:xlink should be xmlnsXlink and so on. There should be no hyphenated attributes and no semi-colons!.

Fill colors with regards to g or path nodes, e.g. fill="black", should be replaced with currentColor ala fill="currentColor". Your mileage may vary depending on the complexity of your SVG.

Pay attention to your custom icon's dimensions and viewBox attribute. It is best to use a viewBox="0 0 512 512" starting point when designing instead of trying to retrofit the viewbox afterwards!

You must source your own SVG into component/view you are working on. This can easily be done in programmatic and maintainable ways.


So long as you have a valid React <SVG> node, you can send it as the customIcon prop and the kit will take care of the rest.


Some Rails applications use only webpack(er) which means using image_url will be successful over image_path in most cases especially development where Webpack Dev Server is serving assets over HTTP. Rails applications still using Asset Pipeline may use image_path or image_url. Of course, YMMV depending on any custom configurations in your Rails application.

Things to Avoid

Be careful of use cases where there should be a clickable area around the icon. Icon Circle Button may need to be used instead.
