What is rc-dropdown?

The rc-dropdown package is a React component that provides a flexible and customizable dropdown menu. It allows developers to create dropdown menus with various content, trigger behaviors, and alignment options.

What are rc-dropdown's main functionalities?

Basic Dropdown

This code sample demonstrates how to create a basic dropdown menu with selectable options. When an option is selected, it triggers an alert with the selected key. The visibility of the dropdown is logged to the console when it changes.

{"import React from 'react';\nimport Dropdown from 'rc-dropdown';\nimport Menu, { Item as MenuItem } from 'rc-menu';\n\nfunction onSelect({ key }) {\n  alert(`selected ${key}`);\n}\n\nfunction onVisibleChange(visible) {\n  console.log(visible);\n}\n\nconst menu = (\n  <Menu onSelect={onSelect}>\n    <MenuItem key='1'>Option 1</MenuItem>\n    <MenuItem key='2'>Option 2</MenuItem>\n    <MenuItem key='3'>Option 3</MenuItem>\n  </Menu>\n);\n\nconst App = () => (\n  <Dropdown\n    overlay={menu}\n    onVisibleChange={onVisibleChange}\n    trigger={['click']}\n  >\n    <a className='ant-dropdown-link' onClick={e => e.preventDefault()}>\n      Click me\n    </a>\n  </Dropdown>\n);\n\nexport default App;"}

Trigger Modes

This code sample shows how to create a dropdown that is triggered by hovering over the link instead of clicking. The menu appears when the user hovers over the 'Hover me' link.

{"import React from 'react';\nimport Dropdown from 'rc-dropdown';\nimport Menu, { Item as MenuItem } from 'rc-menu';\n\nconst menu = (\n  <Menu>\n    <MenuItem key='1'>Option 1</MenuItem>\n    <MenuItem key='2'>Option 2</MenuItem>\n  </Menu>\n);\n\nconst App = () => (\n  <Dropdown\n    overlay={menu}\n    trigger={['hover']}\n  >\n    <a className='ant-dropdown-link' href='#'>\n      Hover me\n    </a>\n  </Dropdown>\n);\n\nexport default App;"}

Alignment

This code sample illustrates how to align the dropdown menu relative to the trigger element. The 'align' prop is used to specify the alignment points, offset, and overflow behavior.

{"import React from 'react';\nimport Dropdown from 'rc-dropdown';\nimport Menu, { Item as MenuItem } from 'rc-menu';\n\nconst menu = (\n  <Menu>\n    <MenuItem key='1'>Option 1</MenuItem>\n    <MenuItem key='2'>Option 2</MenuItem>\n  </Menu>\n);\n\nconst App = () => (\n  <Dropdown\n    overlay={menu}\n    align={{\n      points: ['tr', 'br'],\n      offset: [0, 4],\n      overflow: { adjustX: 1, adjustY: 1 }\n    }}\n  >\n    <a className='ant-dropdown-link' href='#'>\n      Align me\n    </a>\n  </Dropdown>\n);\n\nexport default App;"}
