I am attempting to design a drop-down navigation bar with 2 rows. Initially, only 1 row is visible. Upon clicking the visible row, both rows should appear. Subsequently, when one of the 2 rows is clicked, only that specific row should be displayed. Below are a few images illustrating my desired outcome.
This example showcases what I am aiming for, however, I would like to accomplish it without utilizing jQuery. https://codepen.io/matthewbeta/pen/zioHr
It is partially functional already, yet I am struggling to display Row-B only upon its click. Currently, clicking on Row-A reveals both rows simultaneously. Conversely, selecting Row-B causes Row-A to be the sole visible row.
var select = document.getElementById("select");
var rowB = document.getElementById("rowB");
rowB.style.display = "none";
select.addEventListener("click", function(){
if (rowB.style.display == "none") {
rowB.style.display = "flex";
}
else {rowB.style.display = "none"};
});body {
margin: 0px;
}
