    @boohooOct 13.2021 — You can get all combinations of the length of n with this function:

    ``javascript<i>
    </i>function combinations(items, n) {
    const result = [];

    if (n === 1) return items.map(item =&gt; [item]);

    for (let i = 0; i &lt; items.length - n + 1; i++) {
    result.push(
    ...combinations(items.slice(i + 1), n - 1).map(
    t =&gt; [...items.slice(i, i + 1), ...t]
    )
    );
    }

    return result;
    }<i>
    </i>    `</CODE>
    Then, you can get all possible combination simply with:
    <CODE lang="javascript">    `javascript<i>
    </i>const groups = combinations(checkboxes, 6);<i>
    </i>    ``
