I only need Box Component, but there are many other components In theme Object
like AvatarStyles、DialogStyles tec

what can I do if I only need teams themes?
what can I do if I only need some Components?

Hi @zerofront, there's documentation & example code on the Fluent site about the case when you want to import just a few components & use the teams theme - is this what you're looking for? https://fluentsite.z22.web.core.windows.net/theming-examples

Hi @aneeshack4 , Thank you for your prompt reply

import React from 'react'
import { Button, Icon, Label, Provider, themes } from '@fluentui/react'

export default () => (
  <Provider theme={themes.teams}>
    <Button content="Button" />
    <Button icon="add" iconOnly primary />
    <Button icon="email" content="Send email" secondary />
    <Icon name="emoji" size="larger" />
    <Label content="Label with icon" icon="close" />
  </Provider>
)

For this example, I just want to import Button、icon、Label Component，but in theme object, therer are many style of other component which is unnecessary。

@zerofront I opened #12224 to fix broken exports.

Future items:

• Fix https://github.com/microsoft/fluent-ui-react/issues/2325 to do not reference components in styles, i.e. a theme will not require components
• Remove icons from themes https://github.com/microsoft/fluent-ui-react/pull/2320 to allow import only needed icons

@layershifter - doing some housekeep here. do you think we need to leave this issue open or can be closed?

[layershifter]

@xugao I think that we can close this as a duplicate and keep #12953.
