I'm trying to create pagination with Bootstrap and Angular. For now, it looks like this:
<ul class="pagination">
<li class="page-item" *ngFor="let page of pages" [class.active]="page.isActive">
<span class="page-link btn" (click)="pageChange(page.number)">{{page.text}}</span>
</li>
</ul>
But I can't make buttons behave like buttons/anchors. I would like to see hand cursor while hovering over. How can I do it?
Observe the following:
| `$enable-pointer-cursor-for-buttons` | `true` (default) or `false` |
Add "hand" cursor to non-disabled button elements.|
And in _buttons.scss we have:
.btn {
...
cursor: if($enable-pointer-cursor-for-buttons, pointer, null);
...
}
So changing span to button makes it work
<ul class="pagination">
<li class="page-item" *ngFor="let page of pages" [class.active]="page.isActive">
<button class="page-link btn" (click)="pageChange(page.number)">{{page.text}}</button>
</li>
</ul>

I am trying to hide an element until its previous sibling is hovered over, in css (or scss rather), it looks like this:
.menu-container {
// style with flex etc...
& .menu-item-link {
// style the link...
&+.sub-menu-container {
display: none;
}
&:hover+.sub-menu-container {
display: block;
}
}
}
<ul class="menu-container">
<li class="menu-item-container">
<a class="menu-item-link">Ingredients</a>
<ul class="sub-menu-container">
<li class="sub-menu-item-container">
<a class="sub-menu-link">Fruits</a>
</li>
<li class="sub-menu-item-container">
<a class="sub-menu-link">Vegetables</a>
</li>
<li class="sub-menu-item-container">
<a class="sub-menu-link">Dairy</a>
</li>
<li class="sub-menu-item-container">
<a class="sub-menu-link">Children</a>
</li>
</ul>
</li>
</ul>
How do I achieve this using tailwind?
You're not actually trying to target a sibling in your code, you're trying to target a child element. This is a very simple process when you just want to show a sub-menu dropdown.
Just add group to the hover trigger (.menu-item-link in your case) and group-hover:[some-display-class] to the child. This way the child will change it's display property when the parent element (or itself) is hovered.
You should change your title, also I'd recommend that you don't use Tailwind with class names like that. Please see extracting components for the recommended way to use Tailwind CSS. Of course, you are free to use it how you want but you're better off with plain old CSS if you want to use SCSS and classes like that.
Example with your structure:
<ul>
<li class="group">
<a>Ingredients</a>
<ul class="hidden group-hover:block">
<li>
<a>Fruits</a>
</li>
<li>
<a>Vegetables</a>
</li>
<li>
<a>Dairy</a>
</li>
<li>
<a>Children</a>
</li>
</ul>
</li>
</ul>
Example on Tailwind Play https://play.tailwindcss.com/dFc2zlmqDA
In my Angular 8 application, a fixed navigation bar exists on top of the screen. When a user hovers over a dropdown nav link, a menu will show up.
Now, if the user clicks on one of the menu links, the corresponding page will be opened using Angular Routing:
<div class="nav-left">
<div class="dropdown">
<a class="menu" routerLink="/home">
{{'HOME.TITLE' | translate}}
<span class="icon"><i class="fa fa-fw fa-angle-down"></i></span>
</a>
<div class="dropdown-content">
<a routerLink="/home/welcome">
<span class="icon"><i class="fa fa-fw fa-home"></i></span>
{{'HOME.TITLE' | translate}}
</a>
<a routerLink="/home/news-blog">
<span class="icon"><i class="fa fa-fw fa-newspaper-o"></i></span>
{{'HOME.NEWS_BLOG' | translate}}
</a>
<a routerLink="/home/features">
<span class="icon"><i class="fa fa-fw fa-cubes"></i></span>
{{'HOME.FEATURES' | translate}}
</a>
</div>
</div>
</div>
My SCSS definition has a .dropdown:hover selector that shows a menu only if it is hovered:
.dropdown {
.dropdown-content {
display: none;
}
&:hover {
.dropdown-content {
display: block;
}
}
}
What I would like to achieve is that the navigation menu closes automatically when the user clicks a menu link. Right now, the menu remains open because Angular Router does not reload the page but only replaces the page contents by the selected subpage.
In my opinion, there should be a pure CSS / SCSS solution to this problem, although it would be okay for me if it only works with some TypeScript code. My ideas have been so far:
use a special "click" or "selected" CSS selector to define display: none if a link has been clicked
activate some Angular function (if exists?) that resets the "CSS state" (as if the page would have been reloaded)
write a method to close all navigation menus when a routerLink has been clicked (seems too complicated)
Do you have any recommendations which of the mentioned approaches would fit best and how to realize it?
You could have a listener in your template along the lines of:
<div class="dropdown" [ngClass]="{'visible': menuVisible}" (mouseover)="toggleMenu()" (mouseout)="toggleMenu()">
And in your TS:
menuVisible = false;
toggleMenu() {
this.menuVisible = !this.menuVisible;
}
This would be a very simple implementation. You could also do it using Observables, for example (having a Subject emit for each mouse event).
EDIT: I totally forgot to add the click listener part haha! I think you got the idea though!
I would like to disable the nav-pill hover effect on just one item, the link that changes the language of the page, in my navbar. What is the best way to achieve this using either a bootstrap class or CSS?
<div id="navbarCollapse" class="collapse navbar-collapse">
<ul class="nav nav-pills navbar-right">
<li class="language language-active disabled">NL</li>
<li class="language language-nonactive language-right">EN</li>
<li class="approach-li">Diensten</li>
<li class="about-li">Over ons</li>
<li class="qa-li">Vragen</li>
<li class="about-li">Contact</li>
<li class="navbarpadding">
<form action="afspraak.html">
<button class="btn navbar-btn btn-primary2">Afspraak maken</button>
</form>
</li>
</ul>
</div>
Looking at your html using the class: ".language-nonactive"
You can these styles to go along with it, this will remove the hover of the grey background:
.nav>li.language-nonactive>a:hover, .nav>li.language-nonactive>a:focus {
background-color: transparent;
}
Here is a jsfiddle to show what I've done:
http://jsfiddle.net/ho1sgm1e/
Additionally you could you something like this with jquery:
$(document).ready(function() {
/*disable non active tabs*/
$('.nav li').not('.active').addClass('disabled');
/*to actually disable clicking the bootstrap tab, as noticed in comments by user3067524*/
$('.nav li').not('.active').find('a').removeAttr("data-toggle");
});
source: Bootstrap tabs pills disabling and with jQuery
Furthermore, utilising the disbaled class will effectively disable the button.
Using CSS:
.nav .language-nonactive a:hover {
background:rgba(0,0,0,0);
}

First, I'm aware of this posts:
Activating bootstrap dropdown menu on hover
Bootstrap Dropdown with Hover
How to make twitter bootstrap menu dropdown on hover rather than click
And others, but still not found the correct solution yet, here's what I did so far.
first I used the is-open attribute from the angular-bootstrap dropdown directive like this:
<span class="dropdown" dropdown is-open="status.isopen">
<a
href
class="dropdown-toggle"
ng-mouseenter="status.isopen = true"
ng-mouseleave="status.isopen = false"
>
hover me for a dropdown with angular-bootstrap
</a>
<ul
class="dropdown-menu"
>
<li ng-repeat="choice in items">
<a href>{{choice}}</a>
</li>
</ul>
</span>
that seemed to work but 2 bugs appeared:
the first is when dropdown-toggle element is clicked the dropdown menu is gone clicking again wont bring it back you have to mouseleave then mouse enter the dropdown-tooggle to get the dropdown-menu back.
the second is a css/html problem.
Usually the regular css solution for a dropdown is like this:
<a class="css-dropdown">
hover here with css.
<div class="css-dropdown-menu">
<p>item 1</p>
<p>item 2</p>
<p>item 3</p>
</div>
</a>
Notice the dropdown-menu now is inside the dropdown-toggle element which mean when moving with the mouse from the dropdown-toggle to the dropdown-menu it's moving from parent to child, so basically we still hovering over the dropdown-toggle since we are in it's child, which mean the dropdown-menu will still be visible, on other hand, the bootstrap dropdown works with the click event so having the dropdown-menu as a child of the dropdown-toggle is not needed, but now when someone wants to change the behavior to mouseenter/hover once the mouse leaves the dropdown-toggle the dropdown-menu disappear so we no longer have access to the dropdown-menu elements this is visible in this plunker
To fix the first bug, I just removed the dropdown directive then replaced the is-open with ng-class directive like this.
Change this:
<span class="dropdown" dropdown is-open="status.isopen">
to this:
<span class="dropdown" ng-class="{'open': status.isopen}">
The rest stays the same plunker that fixed the first bug.
The second bug is tricky, since the dropdown-menu is no longer a child of the dropdown-toggle the hover effect wont last while moving from the toggle to the menu, so I did this.
Changed this:
<ul class="dropdown-menu">
to this:
<ul
class="dropdown-menu"
ng-mouseenter="status.isopen = true"
ng-mouseleave="status.isopen = false"
>
That did it but another bug appeared when clicking the dropdown-menu item it stays open, so I kept hacking by doing this.
changed this:
<li ng-repeat="choice in items">
to this:
<li ng-repeat="choice in items" ng-click="status.isopen = false">
That give me the required behavior plunker.
That said, this is not a good solution since a lot of directives are involved here for a simple visual effect, the last plunker I provided contains a css solution with no Bootstrap or AngularJS involved, though it is the required behavior it is not the required html structure or visual result, what I need is to have a space between the dropdown-toggle and the dropdown-menu not a padding of the toggle element just an empty space, which make the css solution not valid in this situation.
So, my question is there a better way of doing this without adding a new plugin/library more clean and easily reusable solution for the hover drop down menu?
First, have the toggling on the top-most parent element (in this case, the <span>)
<span class="btn-group" dropdown is-open="status.isopen" ng-mouseenter="status.isopen = true" ng-mouseleave="status.isopen = false">
<a class="btn btn-primary dropdown-toggle" dropdown-toggle>
Button dropdown <span class="caret"></span>
</a>
<ul class="dropdown-menu" role="menu">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li class="divider"></li>
<li>Separated link</li>
</ul>
</span>
This will allow the behavior you wanted - while still allowing clicking to show/hide the menu ;-)
However there's an annoyance: if you move the mouse cursor slower and pass the small gap between the toggle and menu, it will hide the menu.
So secondly, add a small CSS to remove the gap
.dropdown-menu {
margin-top: 0;
}
See the action in this plunker.
I know you want a solution without adding a new plugin/library, but you (or others seeking for this behavior) might want to try using No Close from Dropdown Enhancements lib to keep the dropdown open even after clicking in one of its options:
Do not close the menu on click on radio add class .noclose.
<div class="btn-group">
<button data-toggle="dropdown" class="btn btn-default dropdown-toggle">
Checked option <span class="caret"></span>
</button>
<ul class="dropdown-menu noclose">
<li>
<input type="radio" id="gr1_1" name="gr1" value="1">
<label for="gr1_1">Option 1</label>
</li>
<li>
<input type="radio" id="gr1_2" name="gr1" value="2">
<label for="gr1_2">Option 2</label>
</li>
<li>
<input type="radio" id="gr1_3" name="gr1" value="3">
<label for="gr1_3">Option 3</label>
</li>
</ul>
</div>
Also add a CSS solution for the hovering problem:
.btn-group:hover .dropdown-menu.noclose {
display: block;
}
.dropdown-menu.noclose {
margin-top: 0px;
}
And, of course, don't forget to import the libs:
<script src="./js/dropdowns-enhancement.min.js"></script>
<link href="./css/dropdowns-enhancement.css" rel="stylesheet"\>
In your case I suggest you to study the Dropdown Enhancements's source code to see how it works and maybe find a more suitable solution.
Try adding this line to your css:
.btn-group:hover>.dropdown-menu { display: block; margin-top: 0; }
You'll have to remove your is-open, ng-mouseenter and ng-mouseleave directives.
Below is the solution I came up with, while working on the same issue.
I used a simple custom directive that:
binds the mouseenter and mouseleave events to the dropdown in order correctly to show/hide the menu.
dynamically adds a custom CSS class to the dropdown menu in order to prevent the menu from disappearing when moving the cursor from the button to the menu. Note that this solution has the advantage of not removing the visual gap between the button and menu.
prevents the menu from disappearing when the button is clicked.
The CSS rule uses a before pseudo-element to fill the gap between the button and the menu. I added the border property which can be uncommented to easily get a visual feedback.
.dropdown-hover-menu::before {
content: '';
position: absolute;
left: 0;
width: 100%;
top: -3px;
height: 3px;
/*border: 1px solid black;*/
}
The HTML structure of the snippet is based on the available examples in the dropdown section of the angular-ui bootstrap documentation
angular.module('app', ['ui.bootstrap'])
.directive('dropdownHover', function() {
return {
require: 'uibDropdown',
link: function(scope, element, attrs, dropdownCtrl) {
var menu = angular.element(element[0].querySelector('.dropdown-menu')),
button = angular.element(element[0].querySelector('.dropdown-toggle'));
menu.addClass('dropdown-hover-menu');
element.bind('mouseenter', onMouseenter);
element.bind('mouseleave', onMouseleave);
button.bind('click', onClick);
function openDropdown(open) {
scope.$apply(function() {
dropdownCtrl.toggle(open);
});
}
function onMouseenter(event) {
if (!element.hasClass('disabled') && !attrs.disabled) {
openDropdown(true);
}
};
function onMouseleave(event) {
openDropdown(false);
};
function onClick(event) {
event.stopPropagation();
}
scope.$on('$destroy', function() {
element.unbind('mouseenter', onMouseenter);
element.unbind('mouseleave', onMouseleave);
button.unbind('click', onClick);
});
}
};
});
.dropdown-hover-menu::before {
content: '';
position: absolute;
left: 0;
width: 100%;
top: -3px;
height: 3px;
/*border: 1px solid black;*/

I need a help. I was doing a drop up menu with share icons.
My problem is this: I'd like that when I pass the mouse over the main-share icon in the footer and than go to select another icon (like facebook), the main icon remains selected like as mouse hover, but it don’t works.
<div class="footer large blue">Footer Blue
<div class="pull-right buttons">
<ul>
<li><a class="btn2 large share2 blue" href="#">Share</a>
<ul>
<li><a class="btn large rss" href="#">RSS</a>
</li>
<li><a class="btn large twitter" href="#">Twitter</a>
</li>
<li><a class="btn large plus" href="#">G+</a>
</li>
<li><a class="btn large facebook" href="#">Fb</a>
</li>
</ul>
</li>
<li><a class="btn2 large btt blue" href="#">Back to Top</a>
</li>
</ul>
</div>
I think the problem is that the elements li and a, are two independent tags.
Watch this image to understand it better what am i saying (because i’m not able to explain it better ._.)

Here's the code:
http://jsfiddle.net/zPavan/KHWJ4/2/
If there are any problems or have suggestions on the code, I thank you for the advice!
Instead of depending on the hovering of the <a> specifically, make it depend on the list item that contains the entire <ul>:
li:hover > .btn2.blue {
background-color: hsl(197, 59%, 30%);
}
I would suggest giving that specific li a class like .share that you can use as well.
http://jsfiddle.net/ExplosionPIlls/KHWJ4/3/
I think this will do it:
.buttons ul li:hover > a {
background-color: #1f5f79;
}
