how to use one state in two component / shere state - reactjs

Question

import React, { useState } from 'react';
export const Context = React.createContext();
export const ContextProvider = ({ children }) => {
const [open, setOpen] = useState(false);
return (
<Context.Provider value={{ open, setOpen }}>{children}</Context.Provider>
);
};
componen1
import React, { useContext } from 'react';
import { Context } from '../context/Context';
export default function SideNav({ surahs }) {
const { open, setOpen } = useContext(Context);
return (
<div className={`${open} bg-red`}></div>
);
}
componen2
import React, { useContext } from 'react';
import { Context } from '../context/Context';
export default function Nav() {
const { open, setOpen } = useContext(Context);
const clickHandler = () => {
setOpen((o) => (o === false ? 'hidden' : 'block'));
};
return (
<button onClick={clickHandler}></button>
);
}
how to trigger component 2, once the button on component 1 is clicked it will trigger component 2 and add or remove block and hidden classes
this confuses me

Answer 1

First, you need a state to monitor which category is currently active.
const [category, setCategory] = useState("All"); // possible values [All, Web, App, Design]
Then, you need to set and unset the item-active class depending on which category is active.
You can do the primitive way
className={`work__item ${category === "All" ? "item-active" : ""}`}
Or using a small utility library clsx
clsx("work__item", { "item-active": category === "All"})
Putting everything together:
import React, { useMemo, useState } from "react";
import "./portfolio.css";
import Menu from "./Menu";
import clsx from "clsx";
const Portfolio = () => {
const [category, setCategory] = useState("All");
// a computed variable "items" which update itself only when "category" is changed
const items = useMemo(
// array filter, get items when category matches or when category is selected to "All"
() => Menu.filter(({ category: c }) => c === category || category === "All"),
[category] // watch "category" state, update "items" when "category" changes
);
return (
<div className="work__filters container">
<span
className={clsx("work__item", { "item-active": category === "All" })}
onClick={() => setCategory("All")}
>
All
</span>
<span
className={clsx("work__item", { "item-active": category === "Web" })}
onClick={() => setCategory("Web")}
>
Web
</span>
<span
className={clsx("work__item", { "item-active": category === "App" })}
onClick={() => setCategory("App")}
>
App
</span>
<span
className={clsx("work__item", { "item-active": category === "Design" })}
onClick={() => setCategory("Design")}
>
Design
</span>
</div>
);
};
