Is it a problem with my browser that this dropdown is not working?
I wanted to add a dropdown menu in a navbar in one of my projects and it wasn't opening, so i took the example from bootstrap and it doesn't even work in a code snippet on jsfiddle.net . I am using Angular2
<div class="dropdown">
<button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria- expanded="true">
Dropdown
<span class="caret"></span>
</button>
<ul class="dropdown-menu" aria-labelledby="dropdownMenu1">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li role="separator" class="divider"></li>
<li>Separated link</li>
</ul>
</div>
It is working, just add the .js file of Bootstrap and jquery.min.js
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<div class="dropdown">
<button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria- expanded="true">
Dropdown
<span class="caret"></span>
</button>
<ul class="dropdown-menu" aria-labelledby="dropdownMenu1">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li role="separator" class="divider"></li>
<li>Separated link</li>
</ul>
</div>
Basically, Dropdown requires Jquery and bootstrap.js to be included in the page.
In Angular, you will not be requiring JQuery. But, bootstrap.js is fully dependent on JQuery.
So the alternative for bootstrap.js in Angular is ngx-bootstrap(https://github.com/valor-software/ngx-bootstrap). By adding ngx-bootstarp as a dependency to your project will help you. Thanks for Volarkin for developing it.
Example http://valor-software.com/ngx-bootstrap/#/dropdowns
I faced similar issue that Nav bar dropdown not working. I fixed it by following the below steps.
In Angular.json add below lines
"scripts": [
"node_modules/jquery/dist/jquery.min.js",
"node_modules/bootstrap/dist/js/bootstrap.min.js",
"node_modules/popper.js/dist/umd/popper.min.js"
]
"styles": [ "node_modules/bootstrap/dist/css/bootstrap.min.css" ]
Because bootstrap has dependencies on both jquery and popper.js

I know it's hard to provide the code for my question but I would like to know how to make Bootstrap dropdown menu can't be closed (remain open) after it has been opened by default?
Thank you
You have to use 2 functions one onclick dropdown and one onclick body
use e.stopPropagation(); to prevent closing...
var flag=true;
$( ".dropdown-toggle" ).click(function(e) {
if (!flag)
e.stopPropagation();
else
flag=false;
});
$(document).on('click', ':not(.dropdown)', function(e) {
if ($(this).closest('.dropdown').length == 0) {
e.stopPropagation();
}
});

This solution stops propagation on the Bootstrap hide (hide.bs.dropdown) event, which stops it from continuing on to the hidden (hidden.bs.dropdown) event. You may read more into it here: http://css-tricks.com/dangers-stopping-event-propagation/
I personally prefer this way also because it uses the built in Bootstrap dropdown events, which could be found here: http://getbootstrap.com/javascript/#dropdowns-events
$(function () {
$('.dropdown.keep-open').on({
"shown.bs.dropdown": function () {
$(this).data('closable', false);
},
"click": function (event) {
$(this).data('closable', false);
},
"hide.bs.dropdown": function (event) {
temp = $(this).data('closable');
$(this).data('closable', true);
return temp;
}
});
});

I have a dropdown in my html:

Wherein, I'm using thymeleaf template in my html. I got to know that, spring thymeleaf does not allow any incomplete options in the working html.
<html xmlns:th="http://www.thymeleaf.org">
And while launching this via Spring Boot App, I get an exception,
Attribute name "uib-dropdown" associated with an element type "div"
must be followed by the ' = ' character.
Can someone help me with what would I assign this uib-dropdown, uib-dropdown-toggle and uib-dropdown-menu options?
You can append angular attributes or directives with data-<ng att>
<div class="btn-group" data-uib-dropdown="" is-open="status.isopen">
<button id="single-button" type="button" class="btn btn-primary" uib-dropdown-toggle ng-disabled="disabled">

</button>
<ul class="dropdown-menu" uib-dropdown-menu role="menu" aria-labelledby="single-button">

I am new to front-end. I want to modify design of bootstrap dropdown button like this:
picture
Bootstrap dropdown code:
<div class="dropdown">
<button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">
Dropdown
<span class="caret"></span>
</button>
<ul class="dropdown-menu" aria-labelledby="dropdownMenu1">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li role="separator" class="divider"></li>
<li>Separated link</li>
</ul>

How can I modify it according to above picture?
see my code below or this fiddle for working demo
.dropdown-menu>li>a{
color: red;
padding: 3px 10px;
}
.dropdown-menu>li>a .fa{
margin-right: 5px;
}
<div class="dropdown">
<button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">
Dropdown
<span class="caret"></span>
</button>
<ul class="dropdown-menu" aria-labelledby="dropdownMenu1">
<li><i class="fa fa-cog"></i>Action</li>
<li><i class="fa fa-cog"></i>Action</li>
<li><i class="fa fa-cog"></i>Action</li>
<li><i class="fa fa-cog"></i>Action</li>
<li><i class="fa fa-cog"></i>Action</li>
</ul>
</div>
There's many ways..
Create a new CSS class with your own style and then add the class to your default jquery dropdown
Overide jquery class
Ex for number 1:
Create new CSS class:
.newDropdown {
background-color: #ddd;
color: #fff
border: 1px solid #000
}
then add .newDropdown to your html
<ul class="dropdown-menu newDropdown" aria-labelledby="dropdownMenu1">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li role="separator" class="divider"></li>
<li>Separated link</li>
</ul>
Ex for number 2:
Just overide the class:
.dropdown-menu {
background-color: #777;
}
.dropdown-menu li {
padding: 10px
}

I am using a dropdown-menu to show the candidate options I can choose. And I also want an input to filter the options, so when I enter something, the dropdown-menu should also be shown. So I want to adjust the width of the dropdown-menu to be equal to the input. And how can I show it when the I enter something in the input?
The html I current use is:
<div class="input-group">
<input type="text" class="form-control" aria-label="...">
<div class="input-group-btn">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<span class="caret"></span>
</button>
<ul class="dropdown-menu dropdown-menu-right">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li role="separator" class="divider"></li>
<li>Separated link</li>
</ul>
</div><!-- /btn-group -->
Actually you are searching for some kind of suggestion search box with given selectable choices if I understood correctly.
See this thread:twitter bootstrap autocomplete dropdown / combobox with Knockoutjs
Solution suggestions: selectize.js or Select2
The aspect of automatically adjusting the dropdown's width to be equal to the input's width is hard to achieve because it would cut off some of your given choices (example: Input is only one character - Dropdown would only show first character of every choice). This can't be what you want to achieve.
possible solution:
$('.dropdown-menu').width($('.input-group').width());
.input-group{
width:33%;
}

<div class="input-group">
<input type="text" class="form-control" aria-label="...">
<div class="input-group-btn">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"><span class="caret"></span></button>
<ul class="dropdown-menu dropdown-menu-right">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li role="separator" class="divider"></li>
<li>Separated link</li>

I am using a Legacy Bootstrap version (2.3) to support a tool that is not planned for upgrade anytime soon.
I am trying to make a simple Filter Style Dropdown & Input Group but I am having some issues with the menus.
Here is my code:
<div id="main" class="container">
<div class="page-header">
<h3 class="text-info">
Training Summary <small>Schedule Breakdown</small>
<span class="pull-right">
<div class="input-prepend input-append">
<button tabindex="-1" data-toggle="dropdown" class="btn dropdown-toggle">
Start Date <span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li class="divider"></li>
<li>Separated link</li>
</ul>
<input class="span2 dp cen" type="text" placeholder="Select a Start Date" name="startDate">
<button tabindex="-1" data-toggle="dropdown" class="btn dropdown-toggle">
End Date <span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li class="divider"></li>
<li>Separated link</li>
</ul>
<input class="span2 dp cen" type="text" placeholder="Select an End Date" name="endDate">
<button class="btn" type="button" name="fetch"><i class="icon-refresh"></i></button>
</div>
</span>
</h3>
</div>
What I am trying to do is get the dropdown menus to fire when you click on the "Start Date" or "End Date" dropdowns. Nothing appears to be happening and I'm not too sure why.
I created a fiddle to show the issue: http://jsfiddle.net/3h6x6ztw/1/
My goal is to get the dropdown menu to show up under the buttons as they normally would in a dropdown menu. Not sure if it's something I am missing or just a syntax issue.
In Bootstrap plugins can be included individually (using Bootstrap's individual *.js files), or all at once (using bootstrap.js or the minified bootstrap.min.js).
Some plugins and CSS components depend on other plugins. If you include plugins individually, make sure to check for these dependencies in the docs. Also note that all plugins depend on jQuery (this means jQuery must be included before the plugin files).
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css">
<!-- jQuery library -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<!-- Latest compiled JavaScript -->
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script>
Also you have to set a content for the button an the ul.dropdown-menu with position: relative because ul.dropdown-menu has position: absolute the default in bootstrap is btn-group
something like this:
<div class="btn-group">
<button tabindex="-1" data-toggle="dropdown" class="btn dropdown-toggle">
Start Date <span class="caret"></span>
</button>
<ul class="dropdown-menu">
<li>Action</li>
</ul>
</div>
