Bootstrap Button groups dropdown

Introduction

In the pages we generate we commonly possess a few feasible alternatives to exhibit as well as a few actions that may possibly be at some point taken pertaining to a particular product or a topic so it would undoubtedly be rather useful assuming that they got an convenient and simple solution designating the controls in charge of the user having one path or a different inside a small group with commonly used appeal and styling.

To handle such cases the most recent version of the Bootstrap framework-- Bootstrap 4 has full assistance to the so called Bootstrap Button groups dropdown which in turn typically are exactly what the title specify-- bunches of buttons covered just as a particular component together with all of the elements within seeming nearly the exact same and so it's simple for the site visitor to pick out the right one and it's much less bothering for the eye since there is definitely no free space among the some components in the group-- it appears as a one button bar using various selections.

The best ways to utilize the Bootstrap Button groups responsive:

Setting up a button group is definitely really simple-- everything you really need is an element along with the class

.btn-group

to wrap in your buttons. This specific generates a horizontally coordinated group of buttons-- just in case you angle for a up and down loaded group employ the

.btn-group-vertical

class in its place.

The size of the buttons inside a group can be universally dealt with so with assigning a single class to the whole group you can certainly acquire both small or large buttons in it-- simply just incorporate

.btn-group-sm

for small-sized or else

.btn-group-lg

class to the

.btn-group

element and all the buttons within will obtain the determined sizing. In contrast to the former version you can't tell the buttons in the group to display extra small since the

.btn-group-xs

class in no longer maintained by the Bootstrap 4 framework. You have the ability to eventually merge a number of button groups in to a toolbar simply just enclosing them in a

.btn-toolbar

element or nest a group within another in order to place a dropdown component in the child button group.

Standard example

Cover a variety of buttons by using

.btn

inside

.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

Combine bunches of Bootstrap Button groups dropdown right into button toolbars for more complex components. Use utility classes as demanded 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 mix up input groups with button groups in your toolbars. Like the example just above, you'll likely really need special utilities though to space items effectively.

<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>

Measurement

As opposed to utilizing button scale classes to each button within a group, just provide

.btn-group-*

to every

.btn-group

, including each one whenever nesting several 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>

Nesting

Set a

.btn-group

inside of an additional

.btn-group

when you desire dropdown menus merged with a set of buttons. ( click this)

<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 variety

Generate a set of buttons show up up and down loaded as opposed to horizontally. Split button dropdowns are not actually assisted here.

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

Popovers and Tooltips

Caused by the certain implementation ( and also additional components), a bit of special casing is demanded for tooltips and also popovers within button groups. You'll need to determine the option

container: 'body'

to stay away from unwanted secondary reactions ( including the component growing wider and/or giving up its round edges whenever the tooltip or popover is caused). ( read this)

Another factor to keep in mind

In order to get a dropdown button in a

.btn-group

set up an additional element carrying the exact same class in it and wrap it around a

<button>

with the

.dropdown-toggle

class,

data-toggle="dropdown"

plus

type="button"

attributes. Next in addition to this

<button>

situate a

<div>

with the class

.dropdown-menu

and establish the links of your dropdown in it ensuring you have certainly specified the

.dropdown-item

class to every one of them. That is actually the easy and quick solution generating a dropdown within a button group. Optionally you can build a split dropdown following the very same routine just setting one more ordinary button before the

.dropdown-toggle

component and clearing out the text message in it with the purpose that just the small triangle pointer remains.

Final thoughts
