bootstrap drop down menu doesn't open - javascript

I am having trouble getting my dropdown's to work. I can get the navbar to show up perfectly, but when I click on "Dropdown" (either of them) it does not display the dropdown menu. I have tried looking on other posts about this, but nothing that fixed everyone's problems helped.
Here is the code

In my case, I loaded bootstrap JS twice. Removed duplicate one and it worked.

The problem is in your stylesheet or bootstrap js Link (look at below). Check again!
<script type="javascript" src="dist/js/bootstrap.js"></script>
<link href="dist/css/bootstrap.css" rel="stylesheet">

I get this to work:

I used the code from http://getbootstrap.com/components/#navbar.
And i get an Error with your jquery version so i used also the link from getbootstrap.com
http://getbootstrap.com/getting-started/#template

I tried openning you code with jsFiddle and it worked perfectly.
maybe there is a problem with one of your bootstrap files..?
Try downloading another bootstrap js file
Here is the working example - https://jsfiddle.net/ckcrogo6/ (The HTML code is exactly the same as the code you posted)
Used the bootstrap files found here - https://www.bootstrapcdn.com/

You have two typos
il instead of li and fadeout instead of fadeOut and you unnecessary load myscript.js as a <link rel="stylesheet" - you can remove that line
If I add the JS and CSS and insert your header it works:
$(function() {
$('ul.nav li.dropdown').hover(function() {
$('.dropdown-menu', this).fadeIn();
}, function() {
$('.dropdown-menu', this).fadeOut('fast');
});
});
$(function() {
$('ul.nav li.dropdown').hover(function() {
$('.dropdown-menu', this).fadeIn();
}, function() {
$('.dropdown-menu', this).fadeOut('fast');
});
});

Bootstrap Dropdown Not Un-Collapsing Menu

I've looked everywhere, but can't seem to find the answer to my solution. I am following a tutorial on how to make a navbar for my website and I am trying to make it mobile friendly as well. I want the navbar to display a button that un-collapses the menu on a smaller device. But even after I added jQuery, it still doesn't open the menu.
Here is my code that I have, hopefully it is just a simple fix that I am overlooking.

there is a mistake in your button. you forgot to place the # in your data-target attribute.

Bootstrap Navigation with more links.. Trying to find a solution with jquery

I'm trying to find a solution for my site navigation that consists with more links. After add more links it display in 2, 3 lines.please check the attached picture.This is after add more links
in above picture, i added blue colored link and rest of all are default bootstrap navigation. I want to keep navigation in one line. if need to see more links, need to click that blue colored link (for testing purpose i set it to display none). also when re sizing the browser it also should keep in one line.
i wrote a jquery code and it works when browser decreasing the size. but when increasing the size it doesn't work by adding one by one again. Is there anyway to do this? Anybody can please help me to solve the issue or by giving an idea.
Thanks
my codes,
$(document).ready(function(e) {
$(document).load($(window).bind("load", resThis));
$(document).load($(window).bind("resize", resThis));
var tot=$('.nav').find('.chld').length;
var pos_top=$('.btn').position().top;
var marg=$('.container').width();
function resThis(){
for(var i=tot; i>=0; i--){
if(pos_top>0){
$( ".nav .chld:nth-child("+i+")" ).addClass('a');
}
pos_top=$('.btn').position().top;
}
}

Demo:https://jsfiddle.net/1rwdc9os/
add Jquery library file.
Use either bootstrap.css or bootstrap.min.css and bootstrap.min.js or bootstrap.js
<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
Try in angular.... This is better than others...
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.names = ["Emil", "Tobias", "Linus"];
});
<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<body>
<div ng-app="myApp" ng-controller="myCtrl">
<select ng-model="selectedName" ng-options="x for x in names">
</select>
</div>
<p>This example shows how to fill a dropdown list using the ng-options directive.</p>
