Basic Select

This code sample demonstrates how to create a basic select dropdown with predefined options. Users can select one of the options from the dropdown.

import Select from 'rc-select';

<Select placeholder="Please select">
  <Select.Option value="option1">Option 1</Select.Option>
  <Select.Option value="option2">Option 2</Select.Option>
</Select>

<Select mode="multiple" placeholder="Please select">
  <Select.Option value="option1">Option 1</Select.Option>
  <Select.Option value="option2">Option 2</Select.Option>
</Select>

Searchable Select

This code snippet enables a search functionality within the select dropdown, making it easier for users to find and select options by typing.

import Select from 'rc-select';

<Select showSearch placeholder="Search to select">
  <Select.Option value="option1">Option 1</Select.Option>
  <Select.Option value="option2">Option 2</Select.Option>
</Select>

Custom Dropdown Render

This example demonstrates how to customize the rendering of the dropdown menu, allowing for additional elements like a custom footer to be added.

import Select from 'rc-select';

<Select dropdownRender={menu => (
  <div>
    {menu}
    <div style={{ padding: '8px', cursor: 'pointer' }}>Custom footer</div>
  </div>
)}>
  <Select.Option value="option1">Option 1</Select.Option>
  <Select.Option value="option2">Option 2</Select.Option>
</Select>
