Playbook Design System

Default

This kit's options prop requires an array of objects, each of which will be used as the selectable options within the dropdown. Each option object can support any number of key-value pairs, but each must contain label and value.

import React from 'react'
import { Dropdown } from 'playbook-ui'

const DropdownDefault = (props) => {

  const options = [
    {
      label: "United States",
      value: "United States",
    },
    {
      label: "Canada",
      value: "Canada",
    },
    {
      label: "Pakistan",
      value: "Pakistan",
    }
  ];  


  return (
  <div>
    <Dropdown
        options={options}
    />
  </div>
  )
}

export default DropdownDefault

Subtle Variant

For the subtle variant, it is recommended that you set the Separators prop to false to remove the separator lines between the options for a more cleaner look.

import React from 'react'
import { Dropdown } from 'playbook-ui'

const DropdownSubtleVariant = (props) => {

  const options = [
    {
      label: "United States",
      value: "United States",
    },
    {
      label: "Canada",
      value: "Canada",
    },
    {
      label: "Pakistan",
      value: "Pakistan",
    }
  ];  


  return (
  <>
     <Dropdown
         options={options}
         separators={false}
         variant="subtle"
    />
  </>
  )
}

export default DropdownSubtleVariant

Subcomponent Structure

The dropdown is built using all of the following subcomponents:

Dropdown.Trigger is the UI component that users interact with to toggle the dropdown.
Dropdown.Container is the floating container that wraps the list of dropdown options.
Dropdown.Option renders options that are passed to the container.
Each of these subcomponents can be altered using global props and/or their respective props. See doc examples below for more information on each.

import React from 'react'
import { Dropdown } from 'playbook-ui'

const DropdownSubcomponentStructure = (props) => {


  const options = [
    {
      label: "United States",
      value: "United States",
    },
    {
      label: "Canada",
      value: "Canada",
    },
    {
      label: "Pakistan",
      value: "Pakistan",
    }
  ];  


  return (
  <div>
    <Dropdown
        options={options}
    >
      <Dropdown.Trigger/>
      <Dropdown.Container>
        {options.map((option) => (
          <Dropdown.Option key={option.id} 
              option={option}
          />
        ))}
      </Dropdown.Container>
    </Dropdown>
  </div>
  )
}

export default  DropdownSubcomponentStructure

With Label

The top-level Dropdown component optionally accepts any string through a label prop to produce a label above your trigger element.

import React from 'react'
import { Dropdown } from 'playbook-ui'

const DropdownDefault = (props) => {

  const options = [
    {
      label: "United States",
      value: "United States",
    },
    {
      label: "Canada",
      value: "Canada",
    },
    {
      label: "Pakistan",
      value: "Pakistan",
    }
  ];  


  return (
  <div>
    <Dropdown
        label="Select a Country"
        options={options}
    >
      {options.map((option) => (
        <Dropdown.Option key={option.id} 
            option={option}
        /> 
      ))}
    </Dropdown>
  </div>
  )
}

export default DropdownDefault

Custom Options

Dropdown.Option subcomponent accepts any child components to customize the options' contents and display. By default, options are Body kit text that is set by the label value from the option object.

import React from 'react'
import { Dropdown, Icon, Body, FlexItem, Flex } from 'playbook-ui'

const DropdownWithCustomOptions = (props) => {

  const options = [
    {
      label: "United States",
      value: "United States",
      areaCode: "+1",
      icon: "🇺🇸",
      id: "United-states"
    },
    {
      label: "Canada",
      value: "Canada",
      areaCode: "+1",
      icon: "🇨🇦",
      id: "canada"
    },
    {
      label: "Pakistan",
      value: "Pakistan",
      areaCode: "+92",
      icon: "🇵🇰",
      id: "pakistan"
    }
  ];  


  return (
  <div>
    <Dropdown
        options={options}
    >
        {options.map((option) => (
          <Dropdown.Option key={option.id} 
              option={option}
          >
            <Flex
                align="center"
                justify="between"
            >
              <FlexItem>
                <Flex>
                  <Icon icon={option.icon} 
                      paddingRight="xs"
                  />
                  <Body text={option.label} />
                </Flex>
              </FlexItem>
              <FlexItem>
                <Body color="light" 
                    text={option.areaCode} 
                />
              </FlexItem>
            </Flex>
          </Dropdown.Option>
        ))}
    </Dropdown>
  </div>
  )
}

export default  DropdownWithCustomOptions

Custom Display

Optionally utilize customDisplay on the Dropdown.Trigger subcomponent to customize its content after an option is selected. The component passed to customDisplay will be rendered to the left of the default text-based display. In this example the Avatar kit is being used.

The placeholder prop can also be used to customize the placeholder text for the default Dropdown.Trigger.

The onSelect prop returns the selected option as an object to be utilized by the dev. In this example we are using the onSelect to set a state with the selected option and using it to customize the customDisplay.

import React, { useState } from 'react'
import { Dropdown, User, Flex, FlexItem, Badge, Avatar } from 'playbook-ui'

const DropdownWithCustomDisplay = (props) => {
  const [selectedOption, setSelectedOption] = useState();

  const options = [
    {
      label: "Jasper Furniss",
      value: "Jasper Furniss",
      territory: "PHL",
      title: "Senior UX Engineer",
      id: "jasper-furniss",
      status: "Offline"
    },
    {
      label: "Ramon Ruiz",
      value: "Ramon Ruiz",
      territory: "PHL",
      title: "Senior UX Designer",
      id: "ramon-ruiz",
      status: "Away"
    },
    {
      label: "Jason Cypret",
      value: "Jason Cypret",
      territory: "PHL",
      title: "VP of User Experience",
      id: "jason-cypret",
      status: "Online"
    },
    {
      label: "Courtney Long",
      value: "Courtney Long",
      territory: "PHL",
      title: "UX Design Mentor",
      id: "courtney-long",
      status: "Online"
    }
  ];

  const CustomDisplay = () => {
    return (
      <>
      {
        selectedOption && (
            <Avatar
                name={selectedOption.label}
                size="xs"
            />
        )
      }
    </>
    )
  };


  return (
  <div>
    <Dropdown
        onSelect={(selectedItem) => setSelectedOption(selectedItem)}
        options={options}
    >
      <Dropdown.Trigger customDisplay={<CustomDisplay/>}
          placeholder="Select a User"
      />
        {options.map((option) => (
          <Dropdown.Option key={option.id} 
              option={option}
          >
            <Flex
                align="center"
                justify="between"
            >
              <FlexItem>
                <User
                    align="left"
                    avatar
                    name={option.label}
                    orientation="horizontal"
                    territory={option.territory}
                    title={option.title}
                />
              </FlexItem>
              <FlexItem>
                <Badge dark
                    rounded
                    text={option.status}
                    variant={`${
                        option.status === "Offline"
                        ? "neutral"
                        : option.status === "Online"
                        ? "success"
                        : "warning"
                    }`}
                />
              </FlexItem>
            </Flex>
          </Dropdown.Option>
        ))}
    </Dropdown>
  </div>
  )
}

export default DropdownWithCustomDisplay

Custom Trigger

Optionally replace the default trigger's select element by passing child components directly to the Dropdown.Trigger.

import React, { useState } from 'react'
import { Dropdown, Icon, Body, FlexItem, Flex, IconCircle } from 'playbook-ui'

const DropdownWithCustomTrigger = (props) => {

const [selectedOption, setSelectedOption] = useState();

  const options = [
    {
      label: "United States",
      value: "United States",
      areaCode: "+1",
      icon: "🇺🇸",
      id: "United-states"
    },
    {
      label: "Canada",
      value: "Canada",
      areaCode: "+1",
      icon: "🇨🇦",
      id: "canada"
    },
    {
      label: "Pakistan",
      value: "Pakistan",
      areaCode: "+92",
      icon: "🇵🇰",
      id: "pakistan"
    }
  ];  


  return (
  <div>
    <Dropdown
        onSelect={(selectedItem) => setSelectedOption(selectedItem)}
        options={options}
    >
        <Dropdown.Trigger>
            <div key={selectedOption ? selectedOption.icon : "flag"}>
                <IconCircle
                    cursor="pointer"
                    icon={selectedOption ? selectedOption.icon : "flag"}
                    variant="royal"
                />
            </div>
        </Dropdown.Trigger>
      <Dropdown.Container maxWidth="xs">
        {options.map((option) => (
          <Dropdown.Option key={option.id} 
              option={option}
          >
            <Flex
                align="center"
                justify="between"
            >
              <FlexItem>
                <Flex>
                  <Icon icon={option.icon} 
                      paddingRight="xs"
                  />
                  <Body text={option.label} />
                </Flex>
              </FlexItem>
              <FlexItem>
                <Body color="light" 
                    text={option.areaCode} 
                />
              </FlexItem>
            </Flex>
          </Dropdown.Option>
        ))}
      </Dropdown.Container>
    </Dropdown>
  </div>
  )
}

export default  DropdownWithCustomTrigger

Custom Option Padding

By default, dropdown option paddingX is set to sm and paddingY is set to xs, but this padding can be overridden using our global padding props. In this example we are setting the option padding to sm all around.

import React from 'react'
import { Dropdown } from 'playbook-ui'

const DropdownWithCustomPadding = (props) => {

  const options = [
    {
      label: "United States",
      value: "United States",
      areaCode: "+1",
      icon: "🇺🇸",
      id: "United-states"
    },
    {
      label: "Canada",
      value: "Canada",
      areaCode: "+1",
      icon: "🇨🇦",
      id: "canada"
    },
    {
      label: "Pakistan",
      value: "Pakistan",
      areaCode: "+92",
      icon: "🇵🇰",
      id: "pakistan"
    }
  ];  


  return (
  <div>
    <Dropdown
        options={options}
    >
      {options.map((option) => (
        <Dropdown.Option key={option.id} 
            option={option}
            padding="sm"
        /> 
      ))}
    </Dropdown>
  </div>
  )
}

export default DropdownWithCustomPadding

Dropdown with Error

import React, { useState } from 'react'
import { Dropdown } from 'playbook-ui'

const DropdownError = (props) => {
    const [selectedOption, setSelectedOption] = useState()
    const error = selectedOption?.value ? null : "Please make a valid selection"
    const options = [
        {
            label: "United States",
            value: "United States",
        },
        {
            label: "Canada",
            value: "Canada",
        },
        {
            label: "Pakistan",
            value: "Pakistan",
        }
    ]

    return (
        <>
            <Dropdown
                error={error}
                onSelect={(selectedItem) => setSelectedOption(selectedItem)}
                options={options}
            />
        </>
    )
}

export default DropdownError

Default Value

import React from 'react'
import { Dropdown } from 'playbook-ui'

const DropdownDefaultValue = (props) => {
  const options = [
    {
      label: "United States",
      value: "United States",
    },
    {
      label: "Canada",
      value: "Canada",
    },
    {
      label: "Pakistan",
      value: "Pakistan",
    }
  ];  

  return (
  <>
    <Dropdown
        defaultValue={options[2]}
        options={options}
    />
  </>
  )
}

export default DropdownDefaultValue

Blank Selection

import React from 'react'
import { Dropdown } from 'playbook-ui'

const DropdownBlankSelection = (props) => {
  const options = [
    {
      label: "United States",
      value: "United States",
    },
    {
      label: "Canada",
      value: "Canada",
    },
    {
      label: "Pakistan",
      value: "Pakistan",
    }
  ];

  return (
  <>
    <Dropdown
        blankSelection="Select one..."
        options={options}
    />
  </>
  )
}

export default DropdownBlankSelection

Clear Selection

To use an external control (like a reset button) to clear Dropdown selection, you can make use of the useRef hook. You must pass a ref to the Dropdown component and use that ref within the onClick for the external control in the way shown in the code snippet below.

import React, { useRef } from 'react'
import { Button, Dropdown } from 'playbook-ui'

const options = [
    {
        label: "United States",
        value: "United States",
    },
    {
        label: "Canada",
        value: "Canada",
    },
    {
        label: "Pakistan",
        value: "Pakistan",
    }
]

const DropdownClearSelection = (props) => {
    const dropdownRef = useRef(null)

    const handleReset = () => {
        if (dropdownRef.current) {
            dropdownRef.current.clearSelected()
        }
    }

    return (
        <>
            <Dropdown
                defaultValue={options[2]}
                options={options}
                ref={dropdownRef}
            />
            <Button
                marginTop="md"
                onClick={handleReset}
                text="Reset"
            />
        </>
    )
}

export default DropdownClearSelection

Separators Hidden

import React from 'react'
import { Dropdown } from 'playbook-ui'

const DropdownSeparatorsHidden = (props) => {

  const options = [
    {
      label: "United States",
      value: "United States",
    },
    {
      label: "Canada",
      value: "Canada",
    },
    {
      label: "Pakistan",
      value: "Pakistan",
    }
  ];  


  return (
  <div>
    <Dropdown
        options={options}
        separators={false}
    />
  </div>
  )
}

export default DropdownSeparatorsHidden
