I have a search results screen showing 10 results (locations in the world) per page. If a result has an image available, the image will show, otherwise it shows the location on an OpenLayers map.
I'm just trying to upgrade this page using Bootstrap carousel to allow users to cycle between the map and the image (if available).
I got carousel working fine using 2 test images. However when I swap in the OL map, although the image/photo shows OK, when you cycle to the next item (the map), the map just shows a white screen / nothing shows.
Code is below. (FYI the map works fine when I pull it out of the carousel code.
Any ideas?
Happy to share the Ol.map code, although as mentioned it runs OK outside of carousel, so I assume it might be some sort of formatting/CSS issue.
<div class="carousel-inner">
<div class="carousel-item active">
<%= image_tag(#phototouse, class:"map img-responsive", style:"display:block;height: 100%;max-height:350px") %>
</div>
<div class="carousel-item">
<div id="<%= location.location_id %>" class="map" style="display:block;height: 100%;max-height:350px"></div>
</div>
</div>
<a class="carousel-control-prev" href="#carouselExampleControls<%= location.location_id %>" role="button" data-slide="prev">
<span class="carousel-control-prev-icon" aria-hidden="true"></span>
<span class="sr-only">Previous</span>
</a>
<a class="carousel-control-next" href="#carouselExampleControls<%= location.location_id %>" role="button" data-slide="next">
<span class="carousel-control-next-icon" aria-hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>
Update:
I thought I had got this working by adding in the updateSize event (below) but weirdly the map only shows when I resize the window. If I don't touch the window, the map doesn't show and I get the following java error: 'map1.updateSize is not a function'.
Any ideas?

I have an app where I'm using custom svg icons using Materials 'MatIconRegistry'.
The import works fine, but a strange thing is happening when I have multiple icons on a page. For some reason, any icons that following an initial icon end up bing the same as the first, even though they are clearly labeled as another icon.
When I comment out the initial icon, the next instance changes to the one being called by that instance, but then all the following icons then change to that icon.
What could be causing this?
Here is the code:
<mat-sidenav-container>
<mat-sidenav mode="side" opened="true" class="app-sidenav">
<div class="logo-wrapper">
<img
class="menu-logo"
alt="Avocado"
src="./assets/logo.png"
/>
</div>
<div>
<div class="menu-item">
<a
class="menu-button"
routerLink="/"
mat-button
routerLinkActive="active"
[routerLinkActiveOptions]="{ exact: true }"
>
<div>
<mat-icon svgIcon="dashboard"></mat-icon>
</div>
<div class="button-label">
Dashboard
</div>
</a>
</div>
<div class="menu-item">
<a
class="menu-button"
routerLink="/sessions"
mat-button
routerLinkActive="active"

<div>
<mat-icon svgIcon="sessions"></mat-icon>
</div>
<div class="button-label">

</div>
<div class="menu-item">
<a

I've pasted my code for a bootstrap carousel below. It doesn't work, but I'm not sure why.

I compared your code snippet to the one on bootstrap's website.
It looks like you're not using the classes on your div's and spans that Bootstrap needs.
For example you have <div class="item"> when the Boostrap documentation shows <div class="carousel-item">. I also noticed you using glyphicon chevron's when you should be using <span class="carousel-control-prev-icon" aria-hidden="true"></span> and <span class="carousel-control-next-icon" aria-hidden="true"></span>.
Basically, after verifying that Bootstrap is correctly imported, you're going to need to go through the Bootstrap documentation code snippet and your own line-by-line to make sure the CSS classes used are the same. You'll probably find it helpful to start with a 2-slide carousel, rather than a 6-slide carousel.
You didn't post what version of Bootstrap you're using, so I assumed version 4.1 (the latest stable version as I'm writing this).
The collapsed navbar for mobile versions will not open. The website is www.insaka.org. This is the navbar code. I could have sworn it was working last time I checked it, but now it is not. Any ideas?
<div class="container">
<nav class="navbar navbar-expand-md fixed-top navbar-dark">
<a class="navbar-brand" href="/">Home</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarsExampleDefault">
<ul class="navbar-nav mr-auto">
<%= render 'layouts/navigation_links' %>
<% render 'layouts/nav_links_for_auth' %>
</ul>
<div>

If you check for javascript errors in the console you will find the problems:
popper.min.js
bootstrap.min.js
holder.min.js
These three js files could not be found.
I am trying to make a slideshow using multiple photos that users uploaded through carrierwave.
This is my post/show.html.erb
<div id = "carousel-example-generic" class= "carousel slide" data-ride= "carousel">
<!-- Wrapper for slides -->
<div class="carousel-inner">
<% #photo_attachments.each do |p| %>
<div class="item active">
<%=image_tag p.avatar_url.to_s%>
</div>
<!-- Controls -->
<a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
</a>
<a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
</a>
<% end %>
</div>
.....
<script type="text/javascript">
$(function(){
$('.carousel').carousel();
});
</script>
I cannot figure it out the way to list one photo per slide:( It is still listing all the photos that I have to scroll :(
You are applying active class to all photos that you use
div class="item active"
but it should be
div class="item"
and add this into your javascript
$( '.item:first' ).addClass( 'active');
