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!

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 have done the similar projects earlier but it was working fine. I don't know why it doesn't work in this project while i have done everything similar
I have been trying this for a whole day. Any help will be appreciated.
You want to extend index.html to homepage.html so you have to call homepage.html in your views.py file.
from django.shortcuts import render
def homepage(request):
return render(request, 'homepage.html')
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 %}

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.
Hello I am developing a django cms for my company but running into issues with the navbar in IE8.
using:
-Python 2.7.6
-Django (1, 7, 8, 'final', 0)
-django-cms 3.1.0
-boostrap 3.3.4
here is my template
{% load cms_tags staticfiles sekizai_tags menu_tags %}
<!DOCTYPE html>

<head>
<title>{% block title %}This is my new project home page{% endblock title %}</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">

{% render_block "css" %}
</head>
<body style="padding-top:60px">

<div class="container">
<div class="navbar navbar-default" role="navigation">
<div class="navbar-header">

<script src="{% static 'js/jquery.js' %}"></script>
<script src="{% static 'bootstrap/js/bootstrap.min.js' %}"></script>
{% render_block "js" %}
</body>
</html>
The issue is the navbar is always collapsed regardless of the screen size
I have already had the navbar working in IE + Bootstrap and that template is like so:
<div class="navbar navbar-default" role="navigation">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
<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="{% url 'core:home' %}">
{% load staticfiles %}
<img alt='Bell logo' src="{% static 'core/images/bell_logo.png' %}">
</a>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li>Liens</li>
<li>Tools</li>
<li>Doc</li>
<li>Wiki</li>
<li>Project</li>
<li>CAB</li>
<li>DB</li>
</ul>
<form class="navbar-form navbar-right" role="search">
<div class="form-group">
<input type="text" class="form-control" placeholder="Search">
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
</div><!-- /.navbar-collapse -->
</div><!-- /.container-fluid -->
</div>
I tried adapting my django cms template so it would look like the one I originally had, but no success. What am I doing wrong?
Had to add respond.js to page, but i thought the cms and django would take care of that
Do you know how to force django bootstrap toolkit to be responsive? I mean e.g the change of navbar when width is small.
I have in base.html:
{% bootstrap_stylesheet_tag %}
{% bootstrap_stylesheet_tag "responsive" %}
what is "translated" to when checked in view source of page:
<link rel="stylesheet" href="//cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/2.3.2/css/bootstrap.css">
<link rel="stylesheet" href="//cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/2.3.2/css/bootstrap-responsive.css">
full base.html content here: https://gist.github.com/andilab/785133e800f023c89689
example rendered # jsfiddle here: http://jsfiddle.net/andilab/4Jqab/

</div>
</div>

A couple of things were missed:
A fluid container for the nav
You need to specify the collapsible part of the navbar
A navbar toggle button
