How do I create a vertical drop down menu where if you can click the mouse on one menu to see the sub menu which stays still there until you click the head menu again to hide the submenu?

Utilize javascript to change the views of your menu items utilizing the style="display:none" and "block".  See example code for reference of how to set this up.
//Scripts relating to examples
//
function change1(){
if(document.getElementById("1Nav").style.display=="block"){
    document.getElementById("1Nav").style.display="none";
}else{
document.getElementById("1Nav").style.display="block"; 
}
document.getElementById("2Nav").style.display="none";
}
function change2(){
 
if(document.getElementById("2Nav").style.display=="block"){
    document.getElementById("2Nav").style.display="none";
}else{
document.getElementById("2Nav").style.display="block"; 
}
document.getElementById("1Nav").style.display="none"; 
}
