Let's code

In index.html inside body tag write this

<div class="container">
    <button class="select" name="select" value="options">options</button>
    <div class="options">
        <p class="item active">option 1</p>
        <p class="item">option 2</p>
        <p class="item">option 3</p>
        <p class="item">option 4</p>
    </div>
</div>

And add some CSS

*{
    margin: 0;
    padding: 0;
    box-sizing: border-box;
}

*:focus{
    outline: none;
}

body{
    width: 100%;
    height: 100vh;
    display: flex;
    justify-content: center;
    align-items: center;
    background: #ff6767;
    font-family: 'roboto', sans-serif;
}

.container{
    position: relative;
}

.select{
    position: relative;
    width: 200px;
    height: 40px;
    border-radius: 10px;
    border: none;
    text-transform: capitalize;
    color: #fff;
    background: #292929;
    text-align: left;
    padding: 0 15px;
    font-size: 16px;
    cursor: pointer;
}

.select::after{
    content: '';
    position: absolute;
    right: 20px;
    top: 50%;
    transform: translateY(-50%) rotate(45deg);
    width: 6px;
    height: 6px;
    border-right: 2px solid #fff;
    border-bottom: 2px solid #fff;
}

.select:hover{
    background: #222222;
}

.select.active{
    background: #222222;
    border-bottom-left-radius: 0;
    border-bottom-right-radius: 0;
}

.options{
    position: absolute;
    top: 40px;
    left: 0;
    width: 100%;
    height: fit-content;
    background: rgba(0, 0, 0, 0.5);
    border-bottom-left-radius: 10px;
    border-bottom-right-radius: 10px;
    overflow: hidden;
    display: none;
}

.options.active{
    display: block;
}

.options .item{
    color: #fff;
    text-transform: capitalize;
    width: 100%;
    height: 30px;
    padding: 0 15px;
    line-height: 30px;
    cursor: pointer;
}

.options .item.active{
    background: #292929;
}

we also need to write JS. So let's write some

const select = document.querySelector('.select');
const optionBox = document.querySelector('.options');
const options = [...document.querySelectorAll('.options .item')];

let activeOption = 0; // default should be 0

window.onclick = (e) => {
    if(!e.target.className.includes('select')){
        select.classList.remove('active');
        optionBox.classList.remove('active');
    } else{
        select.classList.toggle('active');
        optionBox.classList.toggle('active');
    }
}

options.forEach((item, i) => {
    item.onmousemove = () => {
        hoverOptions(i);
    }
})

const hoverOptions = (i) => {
    options[activeOption].classList.remove('active');
    options[i].classList.add('active');
    activeOption = i;
    setValue();
}

window.onkeydown = (e) => {
    if(select.className.includes('active')){
        e.preventDefault();
        if(e.key === 'ArrowDown' && activeOption < options.length - 1){
            hoverOptions(activeOption + 1);
        } else if(e.key === 'ArrowUp' && activeOption > 0){
            hoverOptions(activeOption - 1);
        } else if(e.key === 'Enter'){
            select.classList.remove('active');
            optionBox.classList.remove('active');
        }
    }
}

const setValue = () => {
    select.innerHTML = select.value = options[activeOption].innerHTML;
}

setValue();

I hope you understood everything. If you have any doubt or you find any mistake that I made or you have any suggestion feel free to ask me in comment.

If you are interested in programming and want to know how I a 15yr old teen do coding make these design. You can follow me on my Instagram. I am also planning to post my game development stuff on Instagram.

Looks really nice, but unfortunately this isn't accessible at all to blind/visually impaired users who use screen readers, or users with reduced motor ability who use either the keyboard only or switches. Would love to see an accessible version! Until then, I'm gonna stick to the default semantic <select>...

Ah ! My bad I totally forgot this scenario but no worry you can use this select in your forms you just have to do some changes.

Step 1-. Inside CSS file remove this line

*:focus{
    outline: none;
}

Step 2- Then in JS add focus and blur event to select button

select.onfocus = () => {
    select.classList.add('focus');
}

select.onblur = () => {
    select.classList.remove('focus');
}

Step 3- And last modify window.keypress function little bit.

window.onkeydown = (e) => {
    if(select.className.includes('active') || select.className.includes('focus')){
        if(e.key === 'ArrowDown' && activeOption < options.length - 1){
            e.preventDefault();
            hoverOptions(activeOption + 1);
        } else if(e.key === 'ArrowUp' && activeOption > 0){
            e.preventDefault();
            hoverOptions(activeOption - 1);
        } else if(e.key === 'Enter'){
            e.preventDefault();
            select.classList.remove('active');
            optionsBox.classList.remove('active');
        }
    }
}

And now you can easily access this select button from tab and change options with keys.

I hope you find this helpful.
Thank you.

Thanks so much for that and I managed to create a React version of yours :)

export default function Selector({ label, value, onChange, options }) {
    const selectRef = useRef();
    const optionsRef = useRef();
    const [hover, setHover] = useState('');

    const handleOptions = (e) => {
        if (!e.target.className.includes('select')) {
            selectRef.current.classList.remove('active');
            optionsRef.current.classList.remove('active');
        } else {
            selectRef.current.classList.toggle('active');
            optionsRef.current.classList.toggle('active');
        }
    };
    return (
        <SelectWrapper>
            <label>{label}</label>
            <button ref={selectRef} className="select" onClick={handleOptions}>
                {value}
                <div ref={optionsRef} className="options">
                    {options.map((option, index) => (
                        <p
                            key={index}
                            onClick={onChange}
                            className={hover === option.value || value === option.value ? 'item active' : 'item'}
                            value={option.value}
                            onMouseOver={() => setHover(option.value)}
                        >
                            {option.label}
                        </p>
                    ))}
                </div>
            </button>
        </SelectWrapper>
    );
}
