Customising icons

Icon formats

A lot of the formatting options in Draftail rely on icons for toolbar buttons, allowing an icon?: IconProp attribute. There are multiple possible formats to this IconProp:

• An SVG path data string (the d attribute of <path />), e.g. 'M10 10 H 90 V 90 H 10 Z'.
• An array of paths, e.g. ['M10 10 H 90 V 90 H 10 Z', 'M10 10 H 90 V 90 H 10 Z'].
• An SVG symbol reference, inline or external eg. #square / test.svg#square.

The SVG has to use a 1024x1024 viewbox that will be downscaled to 16x16.

Custom icon implementation

To deal with more complex requirements, the icon prop can also be an arbitrary React component: <Icon icon={<CustomIcon icon="square" />}/>.

For example, with an icon font:

const FontIcon = ({ icon }) => (
  <span className={`icon icon-${icon}`} aria-hidden />
);

// And in the editor props:
entityTypes={[
  {
    type: "EMBED",
    description: "Embed",
    icon: <FontIcon icon="embed" />,
    source: EmbedSource,
    block: EmbedBlock,
    attributes: ["url", "title", "thumbnail"],
  }
]}

Ready-made buttons

To customise the icons of BR, HR, and undo/redo buttons, use the enableHorizontalRule, enableLineBreak, showUndoControl, showRedoControl props, providing them with an objects with icon attributes.
