Jquery . Stop Hover after clicking value

Please help me how to stop the hover effect. I want a Javascript or Jquery code to stop hover after clicking the values and the list of value will stay. And for the "x" button(close), it will close list of value and reset back to hover.
Thanks in advance.
CSS:
.dropbtn {
background-color: #04AA6D;
color: white;
padding: 16px;
font-size: 16px;
border: none;
}
.dropdown {
position: relative;
display: inline-block;
}
.dropdown-content {
display: none;
position: absolute;
background-color: #f1f1f1;
min-width: 160px;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
z-index: 1;
}
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}
.dropdown-content .close{
float:right;
cursor: pointer;
}
.dropdown-content a:hover {background-color: #ddd;}
.dropdown:hover .dropdown-content {display: block;}
.dropdown:hover .dropbtn {background-color: #3e8e41;}
<div class="dropdown">
<button class="dropbtn">Dropdown</button>
<div class="dropdown-content">
<div class="close">x</div>
Value 1
Value 2
Value 3
</div>
</div>

You can use the mouseover and mouseout events to simulate a hover.
So:
document.getElementById('dropbtn').addEventListener('mouseover', ()=>document.getElementById('dropdown-content').style.display = 'blobk')
document.getElementById('dropbtn').addEventListener('mouseout', ()=>document.getElementById('dropdown-content').style.display = 'none')

You can remove all CSS hover and use jquery to open the dropdown on the click button and close it on click time
$(()=> {
const dropOpen = $('.dropbtn');
const dropClose = $('.dropdown-content .close');
dropOpen.on('click', function() {
$(this).next().fadeIn();
});
dropClose.on('click', function() {
$(this).parent().fadeOut();
});
});

Why does adding a second dropdown mess up the JS to close menu when user clicks outside it?

I'm not super familiar with JS. I used the W3Schools tutorial for creating an on-click dropdown menu as a reference and added a second menu. However, only the second dropdown menu listed in the javascript maintains the functionality of closing when the user clicks outside the dropdown. (I can switch the order of the functions listed in the JS, and changing nothing else, that switches which menu has that close-when-click-outside functionality.)
Can anyone help me understand why that is? How to fix it would be a bonus but mostly I just don't get why it works for one menu and not the other.

Thank you!

You are only allowed to have one onclick.
The second will overwrite the first
Instead use eventListener and delegation
Notice I removed the inline click and I now only have one class instead of a class per button
window.addEventListener("load", function() {
// click the dropdown if the user clicks outside it unless that is a button
document.addEventListener("click", function(e) {
const tgt1 = e.target.closest('.dropdown-content');
const tgt2 = e.target.closest('.dropbtn');
if (!tgt1 && !tgt2) {
document.querySelectorAll('.dropdown-content').forEach(div => div.classList.remove('show'));
}
})
document.querySelector(".navbar").addEventListener("click", function(e) {
const tgt = e.target.closest("button");
if (tgt && tgt.matches('.dropbtn')) {
document.querySelectorAll('.dropdown-content').forEach(div => div.classList.remove('show'));
document.getElementById(tgt.dataset.id).classList.add('show');

✨ I'm going to make the smallest possible change to your code to make it work, so that you can best learn what happened. I'm not going to redesign your approach.
window.onclick is a variable, and you are assigning a value to it twice. The second function you assign it, for Dropdown 2, overwrites the first, which was for Dropdown 1.
The problem is easily solved by combining the logic into one function assigned to window.onclick as below.
Another simple, and probably better fix, is to use window.addEventListener("click", function(event) { }) rather than window.onclick.
/* When the user clicks on the button,
toggle between hiding and showing the dropdown content */
function drop1() {
document.getElementById("drop1").classList.toggle("show");
}
/* When the user clicks on the button,
toggle between hiding and showing the dropdown content */
function drop2() {
document.getElementById("drop2").classList.toggle("show");
}
// Close the dropdown if the user clicks outside of it
window.onclick = function(e) {
if (!e.target.matches('.dropbtn1')) {
var drop1 = document.getElementById("drop1");
if (drop1.classList.contains('show')) {
drop1.classList.remove('show');
}
}
if (!e.target.matches('.dropbtn2')) {
var drop2 = document.getElementById("drop2");
if (drop2.classList.contains('show')) {
drop2.classList.remove('show');
}
}

Dear stackoverflow, I am currently coding a top nav bar, with this menu drop-down button, this code works fine, however when clicking the WHITE part of the font awesome icon, it does not trigger the javascript event.
Is there any way to make the menu icon clickable too? or let it be invisible to mouse pointer events.
thank you x

The problem with your current code is that the icon is rendered as a svg within the button. This is an independent element and the onclick attribute does not apply to it.
The best way to solve this is to explicitly set the pointer-events to none for the icon SVG:
.dropbtn > svg {
pointer-events: none
}
The pointer-events property dictates how the UI should respond to events on the object. By setting it to none, we are saying that this object does not process events and they are therefore passed to the object underneath the SVG.
The working snippet showing this can be seen below.
function myFunction() {
document.getElementById("myDropdown").classList.toggle("show");
}
// Close the dropdown if the user clicks outside of it
window.onclick = function(event) {
if (!event.target.matches('.dropbtn')) {
var dropdowns = document.getElementsByClassName("dropdown-content");
var i;
for (i = 0; i < dropdowns.length; i++) {
var openDropdown = dropdowns[i];
if (openDropdown.classList.contains('show')) {
openDropdown.classList.remove('show');
}
}
}
}
.dropbtn {
background-color: #3498DB;
color: white;
padding: 10px;
font-size: 10px;
border: none;
cursor: pointer;
}
.dropbtn:hover, .dropbtn:focus {
background-color: #2980B9;
pointer-events: all;
}
.dropdown {
position: relative;
display: inline-block;
}
.dropdown-content {
display: none;
position: absolute;
background-color: #f1f1f1;
min-width: 160px;
overflow: auto;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
z-index: 1200;
}
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}
.dropdown a:hover {background-color: #ddd; display: block;}
.show {display: block;}
.dropbtn > svg {
pointer-events: none
}
<script src="https://use.fontawesome.com/releases/v5.11.2/js/all.js" data-auto-replace-svg="nest"></script>
<body>
<div id="dropdown">
<button class="dropbtn fas fa-bars fa-2x" onclick="myFunction()" style="visibility: visible;"></button>
<div id="myDropdown" class="dropdown-content">
DROPDOWN CONTENT
DROPDOWN CONTENT
DROPDOWN CONTENT
</div>
</div>
</body>

I mean this could be a simple solution or i might be wrong but this might work. Putting this css code on the menu icon:
pointer-events: none;
Hopefully this helps.

Navigation drop downs dont close when opening another

This is almost working as intended, the drop downs do close when clicking on the screen but they stay open when opening up a new drop down. I would like it so that it also closes the open drop down when opening up a new one. What would I have to change in the script in order to make it do that? Thank you in advance.

Create a simple function that clears all the dropdowns, and fire it before showing each dropdown, as well as clicking on window.
/* When the user clicks on the button, toggle between hiding and showing the dropdown content */
function myFunction(event) {
event.stopPropagation();
closeDropdowns();
document.getElementById("myDropdown").classList.toggle("show");
}
function myFunction2(event) {
event.stopPropagation();
closeDropdowns();
document.getElementById("myDropdown2").classList.toggle("show");
}
function myFunction3(event) {
event.stopPropagation();
closeDropdowns();
document.getElementById("myDropdown3").classList.toggle("show");
}
function closeDropdowns(){
document.getElementById("myDropdown").classList.remove("show");
document.getElementById("myDropdown2").classList.remove("show");
document.getElementById("myDropdown3").classList.remove("show");
}
// Close the dropdown menu if the user clicks outside of it
window.onclick = function(event) {
closeDropdowns();
}

HTML select field with filter

I have a select field where a large amount of published names, could reach hundreds.
What I need is to filter the field, I mean:
That if one was selected and searched, displayed as sample texts for forms and with the possibility of writing a new search deleting the sample text searched before.
That fence as typing the text in the box will display the filtered list of options for the text.
An example would be: if I type D or d in the text box, it displays the list of options Daniel Diego, so for all, and that if you search with Diego then after loading the search text box appears as example Diego.
<select id="id_name" name="name">
<option value="3">Diego </option>
<option value="4">Daniel </option>
<option value="5">Fernando </option>
<option value="6">Luz </option>
<option value="7">Catherine </option>
<option value="8">Samuel </option>
<option value="10">Eduardo </option>
</select>

Try this.
Chosen is a jQuery plugin for the <select> html tag.
Not only does it make your select boxes look nicer, but it adds a very nice search feature at the top of the select box.
The source/demo is found here: https://harvesthq.github.io/chosen/

If you want to go with jQuery then these are great UI options available :
https://select2.org/dropdown
https://jqueryui.com/selectmenu/
https://harvesthq.github.io/chosen/
If you want to use Vanilla JavaScript (without jQuery). This is the best option.
You can customise the colours and button layout as per your choice.

toggle between hiding and showing the dropdown content */
function myFunction() {
document.getElementById("myDropdown").classList.toggle("show");

div = document.getElementById("myDropdown");
a = div.getElementsByTagName("a");
for (i = 0; i < a.length; i++) {
txtValue = a[i].textContent || a[i].innerText;
if (txtValue.toUpperCase().indexOf(filter) > -1) {
a[i].style.display = "";
