I have a dropdown in my webpage. But it shows the menu items only once. ie-It shows the menu items only when I click it for the first time. If I reload the page again then it work again. Following is the code I have written for the dropdown menu.
<!-- Dropdown -->
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbardrop" data-toggle="dropdown">
Shop
</a>
<div class="dropdown-menu">
<a class="dropdown-item" href="#">Shoes</a>
<a class="dropdown-item" href="#">Handbags</a>
</div>
</li>
Thank you.
And this is my header code

Add role="button" to your toggle link:
<a class="nav-link dropdown-toggle" href="#" id="navbardrop" data-toggle="dropdown" role="button">Shop</a>
Also, make sure you have loaded the Bootstrap JS file in your code.

Below is the relevant HTML for my _Layout.cshtml page. My issue is that when you click the dropdown menu, Supporting Tables, nothing happens - nothing drops down. I have even tried many other examples after searching Google, but none worked. Finally, one stylesheet link from an online how-to worked, but it changed the styles of my page, so am looking for a solution that won't do that.
Would appreciate it if someone could take a look and see what I might have wrong/be missing. I think it must be a script src or stylesheet link, but I do not know which one I would need to add or replace. Very new to this, so am sorry for my ignorance. Thank you!

Found this on another stackoverflow post (I had searched here prior to posting the question, but must have used other search terms. I found this on Google.)
I needed to include these script srcs under my link rels and in this order:
<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>

The link to the original solution is here:
Bootstrap 4 Dropdown Menu not working?
Hope that can help others! I had no idea there was a particular order.
You are using Bootstrap but cdn of bootstrap CSS is not included in your head tag. The only thing you have to do is to add this to your head tag :
<link
rel="stylesheet"
href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css"
integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm"

This question already has answers here:
Navbar dropdown (collapse) is not working in Bootstrap 5
(11 answers)
Closed last year.
I'm trying to make a dropdown menu with Bootstrap, but it's not working (there's no dropdown when clicking on the button). However, I can perfecly use the framework to do styling stuff.
The Bootstrap js link is at the bottom of the body tag too. I've tried many things, like changing the CDN link for another one, or trying other type of drop down, but nothing's working still. I've also tried other StackOverflow thread related to my problem, but again, nothing works.
Here's the HTML (I've simplified it for you)
<!DOCTYPE html>

Thank you!
You need to apply 2 changes:
data-toggle has been renamed to data-bs-toggle.
Second, add the dependency to popper.js:
<script src="https://cdn.jsdelivr.net/npm/#popperjs/core#2.9.2/dist/umd/popper.min.js" integrity="sha384-IQsoLXl5PILFhosVNubq5LC7Qb9DXgDA9i+tQ8Zj3iwWAwPtgFTxbJ8NT4GN1R8p" crossorigin="anonymous"></script>
Or use the bootstrap version that has popper compiled in according to https://getbootstrap.com/docs/5.0/getting-started/download/
I'm trying to mix a Pill's Tab with some Collapse Multi targets, so that, when a certain pill is selected, the corresponding pane appears and a secondary pane closes.
In the case below, when Profile is selected the profile tab should appear and the Text div should disappear. When another tab is selected, the corresponding tab should, again, open and the div should also show itself.
I switched the data-bs-target on the profile pill to a class, as it is in the Collapse Multi targets Docs, but it isn't that simple. Also played with the id's but no results.
Can't seem to find a way to do this with only Bootstrap :/

So I have this code below.
Using Bootstrap I would like to have this drop down on the left in the middle of the screen. https://screenshots.firefox.com/WKjwlW5eUiVdS0fO/null How would I do this?
Additional Question: How do I make the 3 lines bigger? Do I just make the navbar-toggler-icon bigger?

Setting the left and right margin to auto might work. Try this! mx-auto - says margin on the x-axis (ie., left and right) is set to auto!

Hope this helps!
Bootstrap includes a flexbox grid system for building layouts. It’s based on a 12 column layout and has multiple tiers. It is basically a css class like any other. Bootstrap comes with these classes predefined.
For example:
<div class="col-lg-12">
This would take up all available screen space
</div>
Then all you have to do is center your content and you will end up with a div that takes up the area you want with content that is centered inside it.
The lg in this example stands for a large area, but there are several of these. They can be used in pairs to change the grid based on the available screen area. These col types are predefined and can be easily referenced.
Using this grid system is going to make whatever you create responsive. It is a joy to work with. I recommend you check it out.
I just haven't been able to figure out the syntax
I am trying to have a drop-down menu appear when I click on the second button.

My first attempt at making a nav menu. (For some reason, I am unable to submit this question without providing "details" so please forgive this meaningless text here)
I think you're missing the call to bootstrap's javascript library which is needed for the hamburger nav. Try adding this after you add the jquery reference (i.e. <script src="...jquery.min.js"...)
