Dropdown

Options

Import

import {
  Dropdown,
  DropdownTrigger,
  DropdownContent,
  DropdownItem,
  DropdownSeparator,
} from "@pelagornis/page/components";

Example

The preview above renders this file. Copy it into src/components/ to start from it.

src/components/DropdownExample.tsx

import {
  Button,
  Dropdown,
  DropdownContent,
  DropdownItem,
  DropdownSeparator,
  DropdownTrigger,
} from "@pelagornis/page/components";

export default function DropdownDemo() {
  return (
    <Dropdown>
      <DropdownTrigger>
        <Button variant="outline">Options</Button>
      </DropdownTrigger>
      <DropdownContent align="start">
        <DropdownItem selected>Edit</DropdownItem>
        <DropdownItem>Duplicate</DropdownItem>
        <DropdownSeparator />
        <DropdownItem disabled>Delete</DropdownItem>
      </DropdownContent>
    </Dropdown>
  );
}

Use in MDX

Dropdown is composed from parts that share React state. Children written in MDX are rendered as separate islands, so the parts can’t reach each other. Put the composition in a .tsx file, like the example above, and import that file instead.

src/content/docs/example.mdx

---
title: Example
---

import DropdownExample from "../../components/DropdownExample";

<DropdownExample client:load />

client:load hydrates the island on page load. Use client:visible for content far down the page.

Use in Markdoc

Markdoc tags render Astro components, and this one needs client state. Wrap the example in an .astro file that hydrates it, then register that file as a tag.

src/components/markdoc/DropdownExample.astro

---
import DropdownExample from "../DropdownExample";
---

<DropdownExample client:load />

markdoc.config.mjs

import { component, defineMarkdocConfig } from "@astrojs/markdoc/config";
import starlightMarkdoc from "@astrojs/starlight-markdoc";
import pageMarkdoc from "@pelagornis/page/markdoc";

export default defineMarkdocConfig({
  extends: [starlightMarkdoc(), pageMarkdoc()],
  tags: {
    "dropdown-example": {
      render: component("./src/components/markdoc/DropdownExample.astro"),
      selfClosing: true,
    },
  },
});
