Last Updated : 11 Jun, 2021

React Evergreen is a popular front-end library with a set of React components for building beautiful products as this library is flexible, sensible defaults, and User friendly. Positioner Component allows the user to position an element to an anchor. It is a utility component. We can use the following approach in ReactJS to use the Evergreen Positioner Component.

Positioner Props:

position: It is used for the position the element that is being positioned is on.
isShown: It is used to show the element being positioned when it is set to true.
children: It is a function that is used to return the element being positioned.
bodyOffset: Denote the minimum distance from the body to the element which is being positioned.
targetOffset: Denote the minimum distance from the target to the element which is being positioned.
target: It is a callback function that should return a node for the target.
initialScale: It is used to denote the initial scale of the element being positioned.
animationDuration: It is used to denote the duration of the animation.
onCloseComplete: It is a function that will be triggered when the exit transition is complete.
onOpenComplete: It is a function that will be triggered when the enter transition is complete.

Creating React Application And Installing Module:

Step 1: Create a React application using the following command:
```
npx create-react-app foldername
```
Step 2: After creating your project folder i.e. foldername, move to it using the following command:
```
cd foldername
```
Step 3: After creating the ReactJS application, Install the required module using the following command:
```
npm install evergreen-ui
```

Project Structure: It will look like the following.

Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.

App.js

import React from 'react'
import { Positioner } from 'evergreen-ui'

export default function App() {

  return (
    <div style={{
      display: 'block', width: 700, paddingLeft: 30
    }}>
      <h4>ReactJS Evergreen Positioner Component</h4>
      <Positioner
        target={() => { console.log("Target Func called!") }}
        children={() => <h5>Sample Content Positioned to left</h5>}
        isShown={true}
        position="left">
      </Positioner>
    </div>
  );
}
