New Dropbox after Checking Checkboxes

I was hoping to find the best way to display a new dropdown for every checkbox that is checked. Every time a user checks that they took a certain medication, a dropdown with question should appear (so if they select four medications, four questions with dropdowns should appear). Right now, I have it working so that one hidden question and dropdown appear when a checkbox is checked. What would be the best way to achieve my desired results?

let hiddenMed = document.querySelector('.questionMed');
let hiddenMedQ = document.querySelector(".hiddenQ");
let initialH2 = hiddenMedQ.innerHTML;

//whenever i call the function, whatever is in the parenthesis is going to be known as element within the function
function selectMeds(element) {
    //when you set the variable to element, it enables you to onclick on the thises instead of when you getElementbyId and it only finds the first one
    let checkBox = element;
    //    let checkBox = document.getElementById("medType");
    //    let text = document.getElementById("text");

    if (checkBox.checked == true) {
        hiddenMed.classList.remove("hidden");
        let medName = checkBox.value;
        hiddenMedQ.innerHTML = initialH2 + medName + "?";



    } else {
                let hiddenMed = document.querySelector('.questionMed');
                hiddenMed.classList.add("hidden");
                hiddenMedQ.innerHTML = initialH2;
    }
}
