.btn-group-vertical

class in its place.

.btn-group-sm

for small-sized or else

.btn-group-lg

class to the

.btn-group

component and all the buttons within will obtain the defined size. Compared with the former version you aren't able to tell the buttons in the group to present extra small given that the

.btn-group-xs

class in no longer supported by Bootstrap 4 framework. You have the ability to ultimately mix a several button groups in to a toolbar simply covering them in a

.btn-toolbar

element or else nest a group in another just to add a dropdown element in the child button group.

One other detail to consider

In order to get a dropdown button inside a

.btn-group

create one more component coming with the same class within it and wrap it around a

<button>

by using the

.dropdown-toggle

class,

type="button"

attributes. Next along with this

<button>

place a

<div>

.dropdown-menu

and produce the hyperlinks of your dropdown within it being sure you have actually specified the

.dropdown-item

class to each one of them. That is certainly the easy and fast way developing a dropdown inside a button group. Additionally you can easily establish a split dropdown following the exact same routine simply setting extra ordinary button just before the

element and getting rid of the text in it with the result that only the small triangle pointer remains.
