Bootstrap Button groups dropdown

Introduction

Inside of the pages we build we commonly possess a handful of achievable options to present or a few actions which in turn can be ultimately taken regarding a specific product or a topic so it would most likely be quite helpful in the event that they had an easy and convenient method designating the controls tasked with the visitor having one course or another within a compact group with commonly used appeal and styling.

To maintain this sort of cases the current edition of the Bootstrap framework-- Bootstrap 4 has whole assistance to the so knowned as Bootstrap Button groups value which in turn commonly are exactly what the name explain-- bunches of buttons covered as a individual component along with all of the elements within looking basically the very same so it is definitely convenient for the visitor to select the right one and it's less bothering for the sight given that there is certainly no free space between the certain features in the group-- it looks as a single button bar having multiple opportunities.

Effective ways to apply the Bootstrap Button groups dropdown:

Building a button group is really uncomplicated-- everything you need is simply an element together with the class

.btn-group

to wrap in your buttons. This specific creates a horizontally straightened group of buttons-- in the event that you want a up and down stacked group utilize the

.btn-group-vertical

class as a substitute.

The scale of the buttons within a group may possibly be widely controlled so using specifying a single class to the whole group you can certainly acquire either large or small buttons in it-- simply just put in

.btn-group-sm

for small-sized or else

.btn-group-lg

class to the

.btn-group

component and all the buttons within will get the defined size. Compared with the former version you can't tell the buttons in the group to display extra small because the

.btn-group-xs

class in no longer maintained by Bootstrap 4 framework. You are able to ultimately mix a number of button groups in a toolbar just enclosing them within a

.btn-toolbar

element or else nest a group in another in order to put in a dropdown component inside the child button group.

Standard instance

Cover a variety of buttons through

.btn

.btn-group

<div class="btn-group" role="group" aria-label="Basic example">
  <button type="button" class="btn btn-secondary">Left</button>
  <button type="button" class="btn btn-secondary">Middle</button>
  <button type="button" class="btn btn-secondary">Right</button>
</div>

Example of the Button Toolbar

Incorporate sets of Bootstrap Button groups label inside button toolbars for additional complex elements. Utilize utility classes like needed to space out groups, tabs, and even more.

<div class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups">
  <div class="btn-group mr-2" role="group" aria-label="First group">
    <button type="button" class="btn btn-secondary">1</button>
    <button type="button" class="btn btn-secondary">2</button>
    <button type="button" class="btn btn-secondary">3</button>
    <button type="button" class="btn btn-secondary">4</button>
  </div>
  <div class="btn-group mr-2" role="group" aria-label="Second group">
    <button type="button" class="btn btn-secondary">5</button>
    <button type="button" class="btn btn-secondary">6</button>
    <button type="button" class="btn btn-secondary">7</button>
  </div>
  <div class="btn-group" role="group" aria-label="Third group">
    <button type="button" class="btn btn-secondary">8</button>
  </div>
</div>

Do not hesitate to combine input groups together with button groups within your toolbars. Much like the good example mentioned above, you'll probably really need some utilities though to space items efficiently.

<div class="btn-toolbar mb-3" role="toolbar" aria-label="Toolbar with button groups">
  <div class="btn-group mr-2" role="group" aria-label="First group">
    <button type="button" class="btn btn-secondary">1</button>
    <button type="button" class="btn btn-secondary">2</button>
    <button type="button" class="btn btn-secondary">3</button>
    <button type="button" class="btn btn-secondary">4</button>
  </div>
  <div class="input-group">
    <span class="input-group-addon" id="btnGroupAddon">@</span>
    <input type="text" class="form-control" placeholder="Input group example" aria-describedby="btnGroupAddon">
  </div>
</div>

<div class="btn-toolbar justify-content-between" role="toolbar" aria-label="Toolbar with button groups">
  <div class="btn-group" role="group" aria-label="First group">
    <button type="button" class="btn btn-secondary">1</button>
    <button type="button" class="btn btn-secondary">2</button>
    <button type="button" class="btn btn-secondary">3</button>
    <button type="button" class="btn btn-secondary">4</button>
  </div>
  <div class="input-group">
    <span class="input-group-addon" id="btnGroupAddon2">@</span>
    <input type="text" class="form-control" placeholder="Input group example" aria-describedby="btnGroupAddon2">
  </div>
</div>

Measurements

Instead of using button measurements classes to each and every button inside a group, simply just bring in

.btn-group-*

to every

.btn-group

, incorporating each one when nesting numerous groups

<div class="btn-group btn-group-lg" role="group" aria-label="...">...</div>
<div class="btn-group" role="group" aria-label="...">...</div>
<div class="btn-group btn-group-sm" role="group" aria-label="...">...</div>

.btn-group

<div class="btn-group" role="group" aria-label="Button group with nested dropdown">
  <button type="button" class="btn btn-secondary">1</button>
  <button type="button" class="btn btn-secondary">2</button>

  <div class="btn-group" role="group">
    <button id="btnGroupDrop1" type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
      Dropdown
    </button>
    <div class="dropdown-menu" aria-labelledby="btnGroupDrop1">
      <a class="dropdown-item" href="#">Dropdown link</a>
      <a class="dropdown-item" href="#">Dropdown link</a>
    </div>
  </div>
</div>

Vertical type

Generate a set of buttons appear up and down loaded instead of horizontally. Split button dropdowns are not actually maintained here.

<div class="btn-group-vertical">
  ...
</div>

Popovers and also Tooltips

Due to the specific setup ( and also additional components), a piece of specific casing is demanded for tooltips and popovers just within button groups. You'll have to define the option

container: 'body'

to stay clear of undesirable lesser consequences (such as the component growing wider and/or losing its round edges the moment the tooltip or popover is activated). ( read here)

Another detail to bear in mind

In order to get a dropdown button inside a

.btn-group

make another feature coming with the very same class inside it and wrap it around a

<button>

by using the

.dropdown-toggle

class,

data-toggle="dropdown"

plus

type="button"

attributes. Next together with this

<button>

made a

<div>

with the class

.dropdown-menu

and set up the web links of your dropdown in it making sure you have actually assigned the

.dropdown-item

class to each one of them. That is actually the simple and quick solution making a dropdown inside a button group. Optionally you have the ability to build a split dropdown following the very same routine simply just setting one more regular button right before the

.dropdown-toggle

element and removing the text in it with the result that simply the tiny triangle pointer remains.
