React.JS creating toggle switch with state

Currently I have a toggle switch from the Semantic UI React library and I am setting the checked property to be defaulted to false on the page.

I want to make it toggable so the user can click on it but I need to add a OnClick event property. I want to create a function to handle this but I don't want to use state hooks which were introduced in React.JS version 16 and am not sure how to go about it.

Here is my ToggleSwitch.tsx file where I create the toggle switch

    import * as React from "react";
import { Checkbox } from 'semantic-ui-react'
import * as PropTypes from "prop-types";

const ToggleSwitch = ({ id, name,label, checked, onclick }) => {

    return (
        <Checkbox
            name={name}
            id={id}
            label={label}
            checked={checked}
            onclick={onclick}
            toggle

        />
    );
}

ToggleSwitch.propTypes = {
    id: PropTypes.string.isRequired,
    checked: PropTypes.bool.isRequired,
    label: PropTypes.string,
    name: PropTypes.string,
    onclick: PropTypes.func,
   
};

export default ToggleSwitch;

I then insert the switch into my subheader.tsx which creates a subheader across multiple pages on my website which now will have this switch

import * as React from "react";
import ToggleSwitch from './new_layout/ToggleSwitch'

interface Props {
    name: string;
  renderAction?: () => any;
}




const SubHeader: React.SFC<Props> = ({ name, renderAction }) => {
    return (
        <div className="settings-submenu">
            <div className="settings-submenu-name">{name}</div>
            <div className="settings-submenu-name">{renderAction && renderAction()}</div>
            <ToggleSwitch name='LayoutToggleSwitch' label='Enable New Layout' id='LayoutToggleSwitch' checked={false} onclick = {} />

        </div>
    
  );
};

export default SubHeader;

I am not sure what to put in my OnClick function to make this switch able to be switched as currently when I click on it, it does not change from its checked value which is false

You can use useState in subHeader component and initialize it with false as the default value.

const [newLayoutEnabled, setNewLayoutEnabled] = useState(false);

const handleToggleSwitchClick = () => {
   setNewLayoutEnabled(!newLayoutEnabled);
}

And then pass newLayoutEnabled and handleToggleSwitchClick to ToggleSwitch component.

Using the checked attribute will prevent you from changing the state of the checkbox by clicking on it: You should probably use defaultChecked={false}.

However, you will still need some state management at some point if you want to interact with the checkbox: You can either use hooks (the React documentation provides a really easy-to-follow introduction to the useState hook), or use a state object you will update on click and pass to the checked attribute.
