I copy pasted this code from bootstrap to make a responsive navbar that turns into a collapsed menu with a button.
I copy pasted into the body tag of an empty template in django.
bootstrap is loaded, I get everything, even the button when the screen size is small enough.
but when I click on the button the menu doesn't expand, the button does nothing.
You may not be using the correct documentation / example code for the version of bootstrap you are loading. The code you pasted is using "data-target" attributes from Bootstrap 1.x through 4.x, whereas Bootstrap 5.x has moved to "data-bs-target" attributes.
These attributes are responsible for the JavaScript which would explain why they load but do not trigger anything when clicked.
First of all please have a look to this official bootstrap 5 documentation it has everything you want in order to start coding using bootstrap 5 and i also didn't understand why you are using bootstrap 4 since there is a newer version of bootstrap.

I supposed to have the navbar like the this. but when I first runserver with my appA, it always show the navbar like a list menu, like the figure 2. If I run another appB runserver and rerun myapp A, the navbar goes normal like figure1. So it looks like if I want to get the normal Navbar in appA, I should first run anther appB and then I can get the normal navbar for appA
This is the navbar what I get if I run appA first after I open my computer. Thak you very much for any kind suggestions. It looks like the problem of static.
I have no idea with this problem..
Navbar's Dropdown doesn't work! with this message

why don't you try scripts tags in the bottom of the file.
you should add scripts tags after </body> tag.
So, here is what I have in my app.py file:
from flask import Flask, render_template
from flask_bootstrap import Bootstrap
app = Flask( __name__)
Bootstrap(app)
#app.route('/')
def hello():
return render_template('index.html')
if __name__ == '__main__':
app.run(debug=True)
Here is what I have in my index.html file:
{% extends "bootstrap/base.html" %}
{% block navbar %}
<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">

</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">

</form>
</div>
</nav>
{% endblock %}
{% block content %}
{% endblock %}
First picture is what I expect to see, second picture is what I actually get. I've cleared all cache on my browsers, tried Google Chrome and Mozilla Firefox. Please advise.
Flask boostrap is dead i think the last commit was made over 3 years ago...
https://getbootstrap.com/docs/4.3/getting-started/introduction/
Use that starter template as your base.html and add the navbar there.
I am working through a Flask tutorial but I can't make the Bootstrap navbar work. I think I have all my code as the tutorial specified and my folder tree is as it should be.
My app.py:
from flask import Flask, render_template
app = Flask(__name__)
#app.route('/')
def index():
return render_template('index.html')
if __name__ == '__main__':
app.run(debug=True)
index.html:
{% extends 'layout.html' %}
{% block body %}
HOME
{% endblock %}
layout.html:
<html>
<head>
<meta charset="utf-8">
<title>MyFlaskApp</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">
</head>
<body>
{% include 'includes/_navbar.html' %}
{% block body %}{% endblock %}
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>
</body>
</html>
_navbar.html:
<nav class="navbar navbar-default">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">MyFlaskApp</a>
</div>
<div id="navbar" class="collapse navbar-collapse">
<ul class="nav navbar-nav">
<li>Home</li>
<li>About</li>
<li>Contact</li>
</ul>
</div><!--/.nav-collapse -->
</div>
</nav>
Folder structure is as follows:
Try adding the following code to your layout.html file,
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#">MyFlaskApp</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNav">
<ul class="navbar-nav">
<li class="nav-item active"><a class="nav-link" href="/">Home</a></li>
<li class="nav-item"><a class="nav-link" href="/about">About</a></li>
<li class="nav-item"><a class="nav-link" href="/articles">Articles</a></li>
</ul>
</div>
It will give the following output,
Add Bootstrap Bundle it will work perfectly!
