docs/guide/preact/advanced/combining-icons.md
You can combine multiple icons into a single icon by nesting SVG elements. This is useful if you want to create custom icons by combining existing ones.
::: sandpack {showTabs=false editorHeight=400 editorWidthPercentage=60 dependencies="lucide-preact"}
import { Scan, User } from "lucide-preact";
import { h } from "preact";
function App() {
return (
<div className="app">
<Scan size={48}>
<User
size={12}
x={6}
y={6}
absoluteStrokeWidth
/>
</Scan>
</div>
);
}
export default App;
:::
This is valid, since SVGs can be nested, and all SVG properties are supported on the icons.
The x and y coordinates can be adjusted to position the icons as you like.
::: info Limitation
When combining icons, you need to make sure that the x and y coordinates are within the viewBox of the outer icon (24x24).
:::
You can also combine Lucide icons with native SVG elements to build custom icon variations.
For example, you can add a notification badge to an icon by using the circle SVG element.
::: sandpack {showTabs=false editorHeight=580 editorWidthPercentage=60 dependencies="lucide-preact"}
import { Mail } from "lucide-preact";
import { h } from "preact";
function App() {
const hasUnreadMessages = true;
return (
<div className="app">
<Mail size={48}>
{hasUnreadMessages && (
<circle
r="3"
cx="21"
cy="5"
stroke="none"
fill="#F56565"
/>
)}
</Mail>
</div>
);
}
export default App;
:::
You can also use the text SVG element to add text to your icon.
::: sandpack {showTabs=false editorHeight=400 editorWidthPercentage=60 dependencies="lucide-preact"}
import { File } from "lucide-preact";
import { h } from "preact";
function App() {
return (
<div className="app">
<File size={48}>
<text
x={7.5}
y={19}
font-size={8}
font-family="Verdana,sans-serif"
stroke-width={1}
>
JS
</text>
</File>
</div>
);
}
export default App;
