I need a standard drop down menu to close on mouseout.
I tried a few things, but so far, nothing is working.
<select>
<option value="0" selected="selected" disabled="disabled">Options</option>
<option value="A">A</option>
<option value="B">B</option>
<option value="C">C</option>
<option value="D">D</option>
</select>
It seems that you can’t do this with a standard <select>
, at least not in the browsers I tried.
However, you can do it with a custom select. This snippet contains a modified version of the code from w3schools.
var x, i, j, l, ll, selElmnt, a, b, c;
/* Look for any elements with the class "custom-select": */
x = document.getElementsByClassName("custom-select");
l = x.length;
for (i = 0; i < l; i++) {
selElmnt = x[i].getElementsByTagName("select")[0];
ll = selElmnt.length;
/* For each element, create a new DIV that will act as the selected item: */
a = document.createElement("DIV");
a.setAttribute("class", "select-selected");
a.innerHTML = selElmnt.options[selElmnt.selectedIndex].innerHTML;
x[i].appendChild(a);
/* For each element, create a new DIV that will contain the option list: */
b = document.createElement("DIV");
b.setAttribute("class", "select-items select-hide");
for (j = 1; j < ll; j++) {
/* For each option in the original select element,
create a new DIV that will act as an option item: */
c = document.createElement("DIV");
c.innerHTML = selElmnt.options[j].innerHTML;
c.addEventListener("click", function(e) {
/* When an item is clicked, update the original select box,
and the selected item: */
var y, i, k, s, h, sl, yl;
s = this.parentNode.parentNode.getElementsByTagName("select")[0];
sl = s.length;
h = this.parentNode.previousSibling;
for (i = 0; i < sl; i++) {
if (s.options[i].innerHTML == this.innerHTML) {
s.selectedIndex = i;
h.innerHTML = this.innerHTML;
y = this.parentNode.getElementsByClassName("same-as-selected");
yl = y.length;
for (k = 0; k < yl; k++) {
y[k].removeAttribute("class");
}
this.setAttribute("class", "same-as-selected");
break;
}
}
h.click();
});
b.appendChild(c);
}
x[i].appendChild(b);
a.addEventListener("click", function(e) {
/* When the select box is clicked, close any other select boxes,
and open/close the current select box: */
e.stopPropagation();
closeAllSelect(this);
this.nextSibling.classList.toggle("select-hide");
this.classList.toggle("select-arrow-active");
});
}
function closeAllSelect(elmnt) {
/* A function that will close all select boxes in the document,
except the current select box: */
var x, y, i, xl, yl, arrNo = [];
x = document.getElementsByClassName("select-items");
y = document.getElementsByClassName("select-selected");
xl = x.length;
yl = y.length;
for (i = 0; i < yl; i++) {
if (elmnt == y[i]) {
arrNo.push(i)
} else {
y[i].classList.remove("select-arrow-active");
}
}
for (i = 0; i < xl; i++) {
if (arrNo.indexOf(i)) {
x[i].classList.add("select-hide");
}
}
}
/* If the user clicks anywhere outside the select box,
then close all select boxes: */
document.addEventListener("click", closeAllSelect);
document.querySelector('.select-items').addEventListener('mouseleave', closeAllSelect)
/* The container must be positioned relative: */
.custom-select {
position: relative;
font-family: Arial;
}
.custom-select select {
display: none; /*hide original SELECT element: */
}
.select-selected {
background-color: DodgerBlue;
}
/* Style the arrow inside the select element: */
.select-selected:after {
position: absolute;
content: "";
top: 14px;
right: 10px;
width: 0;
height: 0;
border: 6px solid transparent;
border-color: #fff transparent transparent transparent;
}
/* Point the arrow upwards when the select box is open (active): */
.select-selected.select-arrow-active:after {
border-color: transparent transparent #fff transparent;
top: 7px;
}
/* style the items (options), including the selected item: */
.select-items div,.select-selected {
color: #ffffff;
padding: 8px 16px;
border: 1px solid transparent;
border-color: transparent transparent rgba(0, 0, 0, 0.1) transparent;
cursor: pointer;
}
/* Style items (options): */
.select-items {
position: absolute;
background-color: DodgerBlue;
top: 100%;
left: 0;
right: 0;
z-index: 99;
}
/* Hide the items when the select box is closed: */
.select-hide {
display: none;
}
.select-items div:hover, .same-as-selected {
background-color: rgba(0, 0, 0, 0.1);
}
