I have created a custom CSS select and need help to make the #drop in form of a modal.
So that whenever a user clicks on the dropdown button, it will open a modal containing a list of options. And selecting a list will show information on that particular list option.
Also, the #drop div does not appear in the middle of the screen.
I'm new to JS and have managed to create a structure. I'm sharing the code below. Please help me with the modal so that the entire thing works perfectly.
Thanks in advance.
PS: If you think there's some easy way of doing this please add the code to the answer.

I'm trying to populate a dropdown menu with jquery with a series of elements (projects) but it doesn't work. From the interface I see the button "dropdown", but if I click it I don't see anything, how can I solve this? When I click it I should see the list of projects that I pass to it (see loop for javascript)

The issue is that you have no way to display the drop down. There's a comment that says "add [.show] on click" - but you can also do this with hover css, so no need for js.
.dropbtn:hover + .dropdown-content {
display:block;
}
Adding that to your (otherwise working snippet) gives:
var result = {
"status": 0,
"message": "OK",
"projects": ["p1", "p2", "p3"]
}
for (var i = 0; i < result.projects.length; i++) {
$('#myDropdown').append('<a data-id= "' + i + '">' + result.projects[i] + '</a>');
}
.dropbtn:hover + .dropdown-content {
display:block;
}
.dropbtn {
background-color: #3498DB;
color: white;
padding: 16px;
font-size: 16px;
border: none;
cursor: pointer;
}
/* Dropdown button on hover & focus */
.dropbtn:hover,
.dropbtn:focus {
background-color: #2980B9;
}
/* The container <div> - needed to position the dropdown content */
.dropdown {
position: relative;
display: inline-block;
}
/* Dropdown Content (Hidden by Default) */
.dropdown-content {
display: none;
position: absolute;
background-color: #f1f1f1;
min-width: 160px;
box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);

If you do want it on click, then you need to add a click handler, eg:
$(".dropbtn").click(() => { $(".dropdown-content").toggleClass("show") });
Giving:
var result = {
"status": 0,
"message": "OK",
"projects": ["p1", "p2", "p3"]
}
for (var i = 0; i < result.projects.length; i++) {
$('#myDropdown').append('<a data-id= "' + i + '">' + result.projects[i] + '</a>');
}
$(".dropbtn").click(() => { $(".dropdown-content").toggleClass("show") });
.dropbtn {
background-color: #3498DB;
color: white;
padding: 16px;
font-size: 16px;

cursor: pointer;
}
/* Dropdown button on hover & focus */

I started writing a responsive navigation bar (4 menu item) with two clickdowns. Now, I would like to add a third one. But when I add a third one, it won't dropdown. Earlier someone helped me with the second one (which also didn't drop down) and it works. So I thought I'd just copy the JS from the second one but that didn't work. Can someone tell me what I need to do in order for the third one to also dropdown? Thx!

You are calling myFunction3 but not defined you have to create myFunction3 in
js.
function myFunction3() {
document.getElementById("myDropdown3").classList.toggle("show");
}
Appreciate if useful.
Your onClick buttons should be ...
<button onclick="myFunction('myDropdown')" class="dropbtn">ONS AANBOD</button>
<button onclick="myFunction('myDropdown2')" class="dropbtn">PORTFOLIO</button>
<button onclick="myFunction('myDropdown3')" class="dropbtn">SPELERS</button>
... and your function myFunction should look like this:
function myFunction(id) {
document.getElementById(id).classList.toggle("show");
}
/* When the user clicks on the button,
toggle between hiding and showing the dropdown content */
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];

What is the problem here? It should dropdown 2 different things when i click the specific button .. but it doesn't.
If i click dropdown it shows home about contact. If i click dropdown 2, same home about contact, but i want it to be home2 about2 contact2.
The entire website contains 5 parallax slides. It is a project for school, to obtain some sort of license, so i'm really trying to understand that code ( and mostly i do ). I understand every "function" but when i combine them all... i just screw up.
So, please, be as clear as you can. Thank you !
P.S: Excuse my bad english, it's not my first language.. :(
You are using the same ID for two different div elements.
IDs must be unique.
You may solve this issue simply adding the id text and event object to your inline events:
<button onclick="myFunction('myDropdown1', event)" class="dropbtn">Dropdown</button>
<button onclick="myFunction('myDropdown2', event)" class="dropbtn">Dropdown2</button>
And so you can change your function in order to handle the parameters.
When clicking on a dropbtn button:
stop event propagation in order to avoid the window.onclick execution
hide/remove show class to the dropdown-content div if any
toggle the show class on the current dropdown-content div
When clicking on the window be sure to be outside the dropdown-content visible div and dropbtn buttons.
For more details take a look to:
var elt = element.closest(selectors);:
The Element.closest() method returns the closest ancestor of the current element (or the current element itself) which matches the selectors given in parameter. If there isn't such an ancestor, it returns null.
- >var result = element.matches(selectorString);
The snippet:
/* When the user clicks on the button,
toggle between hiding and showing the dropdown content */
function myFunction(eleId, event) {
//
// stop event propagation in order to avoid the window.onclick execution
//
event.stopPropagation();
//
// remove show class to previous shown div
//
document.querySelectorAll('.dropdown-content.show').forEach(function(ele, idx) {
ele.classList.remove("show");
});
//
// select by id using the param value
//
document.getElementById(eleId).classList.toggle("show");
}
// Close the dropdown if the user clicks outside of it
window.onclick = function(event) {
//
// if not a button and not a dropdown-content....
//
if (!event.target.matches('.dropbtn') && event.target.closest('.dropdown-content') == null) {
//
// remove show class to previous shown div
//
document.querySelectorAll('.dropdown-content.show').forEach(function(ele, idx) {
ele.classList.remove("show");
});
}

I want to be able to open a drop down menu, and when I select one of the options, a small window will popup with more options available. Something shown in this picture I found: http://datasmugglers.com/wp-content/uploads/mute-someone.jpg
I tried some solutions I found but no matter what I do it doesn't seem to work. I can't find any errors but I'm trying to do it exactly like the template someone gave me in my last question and its just not working.
//toggles the hidden dropdown
function dropdown() {
document.getElementById("myDropdown").classList.toggle('show');
}
//opens a popup window from clicking settings
function settings() {
document.getElementById('settingsD').classList.toggle('show');

As you can see I can't click on the settings part of the dropdown and have the settings text show, and I'm not sure why. Thank you for your help in advance!
You have to place the .show below .settings in your css. If you have it like you do the display:block; in .show gets overwritten by the display:none; in .settings which is below.
Else you could do .settings:not(.show) if none of the css for .settings should be displayed.
