How to implement Menu in MVC 5 - html

A MVC 5 project was created and you want to change the menu of this one, for it resorted to Bootwatch, the menu that you want to implement is the following
The first thing I did was change the general style of my project, download the bootstrap.css file
and then I replaced it with my BundleConfig because of the previous one I had, this modifies the style of my project, but does not include the aforementioned navbar
To put the Navbar that you want, implement the following code in my _Layout.cshtml:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>#ViewBag.Title - Muebles Pangal</title>
#Styles.Render("~/Content/css")
#Scripts.Render("~/bundles/modernizr")
</head>
<body>
<div class="container">
<nav class="navbar navbar-expand-lg navbar-dark bg-success">
<a class="navbar-brand" href="#">Muebles Pangal</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarColor01" aria-controls="navbarColor01" aria-expanded="false" aria-label="Toggle navigation" style="">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarColor01">
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#Url.Action("Index", "Categorias")">Categorias </a>
</li>
<li class="nav-item">
<a class="nav-link" href="#Url.Action("Index", "Productoes")">Productos </a>
</li>
<li class="nav-item">
<a class="nav-link" href="#Url.Action("Index", "Ubicacions")">Proveedores </a>
</li>
</ul>
<form class="form-inline my-2 my-lg-0">
<input class="form-control mr-sm-2" placeholder="Buscar" type="text">
<button class="btn btn-secondary my-2 my-sm-0" type="submit">Buscar</button>
</form>
</div>
</nav>
</div>
<div class="container body-content">
#RenderBody()
<hr />
<footer>
<p>© #DateTime.Now.Year - Sistema Bodega</p>
</footer>
</div>
#Scripts.Render("~/bundles/jquery")
#Scripts.Render("~/bundles/bootstrap")
#RenderSection("scripts", required: false)
</body>
</html>
But when executing my project I find the following problem, my menu does not work in a good way to the responsive call, this means that when I change (shrink) the size of my browser and call the menu from my <span class = "navbar- toggler-icon "> </ span> this is displayed, but it immediately collapses again.
So it does not work in the right way, I've been trying to solve this for days but I have not had good results.
I have installed the Bootstrap and Bootstrap.less packages, could someone help me? what's going on?
any help for me?

You are missing jQuery.min.js i believe, or it might be placed in the wrong order in your code structure. Hope this snippet helps!!
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/js/bootstrap.min.js"></script>

<nav class="navbar navbar-expand-lg navbar-dark bg-success">
<a class="navbar-brand" href="#">Muebles Pangal</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarColor01" aria-controls="navbarColor01" aria-expanded="false" aria-label="Toggle navigation" style="">
<span class="navbar-toggler-icon"></span>

</li>
<li class="nav-item">
<a class="nav-link" href="#Url.Action(" Index ", "Ubicacions ")">Proveedores </a>
</li>
</ul>
<form class="form-inline my-2 my-lg-0">
<input class="form-control mr-sm-2" placeholder="Buscar" type="text">
<button class="btn btn-secondary my-2 my-sm-0" type="submit">Buscar</button>
</form>
</div>
</nav>

Can you check your css for the following:
.navbar-collapse.collapse {
display: none!important;
}
I am able to get a working menu in a new MVC 5 project using what you posted, but I do not have the same css as you.
Please see a similar problem: Bootstrap mobile menu wont stay open

Why my bootstrap toggler is not showing items?

Im using bootstrap version5 and learning about navbar togglers but my togler is not showing any content on clicking.
Here is my code.
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<div class="container-fluid">
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarTogglerDemo01" aria-controls="navbarTogglerDemo01" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarTogglerDemo01">
<a class="navbar-brand" href="#">Hidden brand</a>
<ul class="navbar-nav me-auto mb-2 mb-lg-0">
<li class="nav-item">
<a class="nav-link active" aria-current="page" href="#">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>
<form class="d-flex">
<input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-success" type="submit">Search</button>
</form>
</div>
</div>
</nav>
In learning bootstrap and creating a navbar using nav, So I used navbar toggler for small devices so I kept all my links in a toggler button but while clicking on toggler button nothing is showing
And this what I get.
The HTML markup you have shared with your post is correct. It should show the navigation panel while clicking on the toggle button.
I think you have not included the Bootstrap JavaScript file properly with your page. That is why the panel is not responding while clicking on the button.
Add the bootstrap JavaScript file to your page and it will work properly as you expected.
<script src="https://cdn.jsdelivr.net/npm/bootstrap#5.2.0-beta1/dist/js/bootstrap.bundle.min.js"></script>
<link href="https://cdn.jsdelivr.net/npm/bootstrap#5.2.0-beta1/dist/css/bootstrap.min.css" rel="stylesheet"/>
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<div class="container-fluid">
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarTogglerDemo01" aria-controls="navbarTogglerDemo01" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarTogglerDemo01">
<a class="navbar-brand" href="#">Hidden brand</a>
<ul class="navbar-nav me-auto mb-2 mb-lg-0">
<li class="nav-item">
<a class="nav-link active" aria-current="page" href="#">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">

Change data-bs- to data- in your toggle button.

Your code is quite good but You missed to hook up bootstrap5 correctly ;-)
As we can read in official docs:
Include Bootstrap’s CSS and JS. Place the tag in the for
our CSS, and the tag for our JavaScript bundle (including
Popper for positioning dropdowns, poppers, and tooltips) before the
closing </body>.

You can also include Popper and our JS separately. If you don’t plan
to use dropdowns, popovers, or tooltips, save some kilobytes by not
including Popper.

Did you include the Bootstrap js file ? If not, the nav bar won't work properly.

Bootstrap dropdown giving glitch with inner CSS style

I built a header using bootstrap. But, when I use a inner stylesheet on that page for other elements the dropdown has a glitch. Doing Upper lower bootstrap CDN or jQuery CDN link doesn't fix my problem. Header only works whenever there is not inner stylesheet or external stylesheet link. How can I solve this problem?
This is the problem I am facing right now

Cannot get bootstrap dropdown to work with local files offline

so I have been looking for how to solve this and it's been over a day now.
I have bootstrap version 4.5.2 downloaded locally. I have linked it to my html page and it seems to already be working, but one thing I cannot seem to get to work is the dropdown menu. I tried it with the exact same code in bootstrap website but it doesn't seem to want to work. If anyone could help I would appreciate it very much, thank you all! Also note that when I use the cdn everything works but I want it to work offline if possible.
I will link the code below.

To make bootstrap work offline. you have to link the boostrap javascript to your project. It comes with the downloaded file. Also you have to link the dependencies.

I have used your same code and just use online CDN in my code it's works fine for the same code you are provided. Compare your code with mine and find what was the mistake.

Why does my nav bar add menu items in a vertical fashion?

I'm learning to work with Bootstrap, I made a menu, but the menu items get added in the right side, vertically, instead of the left side, horizontally. Help me identify my mistake.

The webpage I see,
Help me find where I have gone wrong.
This is because you are leaving out important components i.e. stuff that's designed to be part of the Bootstrap navbar. Include those components back in and everything will show up as intended.
Bootstrap 4 is designed to be mobile first.
So, if you leave out the navbar-toggler components, then you get what you see because on mobile devices the navigation is stacked vertically.
Use this sample code as a template:
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarSupportedContent">
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown
</a>
<div class="dropdown-menu" aria-labelledby="navbarDropdown">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<div class="dropdown-divider"></div>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
<form class="form-inline my-2 my-lg-0">
<input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
</form>
</div>
</nav>
P.S. The most recent version of Bootstrap 4 is beta 3. Beta 3 did introduce a few breaking changes as opposed to beta 2. (although none of them affect the navbar components)
You should add navbar-expand-lg class on <nav> and mr-auto in ul like following way:
<nav class="navbar navbar-default navbar-expand-lg " id="navbar">
<div class="container-fluid">
<div class="navbar-header">
Brand
</div>
<ul class="nav navbar-nav mr-auto" >
<li> Home <span class="caret"></span></li>
<li>Team</li>
