Input groups

Easily extend form controls by adding text, buttons, or button groups on either side of textual inputs, custom selects, and custom file inputs.

Place one add-on or button on either side of an input. You may also place one on both sides of an input. Remember to place <label>s outside the input group.

Input group components

Icons

Add icons simply by placing them in the .input-group-text element. By default, items in the .input-group-text element are vertically aligned in the center. For larger input groups, such as <textarea>s, you can reset this behavior to place the icon at the top again by adding the flex styling utility class .align-items-start. 


<div class="form-group">
	<label>Input with icon</label>
	<div class="input-group">
		<div class="input-group-prepend">
			<span class="input-group-text"><i class="fas fa-user"></i></span>
		</div>
		<input type="text" placeholder="Username" class="form-control" id="inputDefault1">
	</div>
</div>

<div class="form-group">
	<label>Textarea with icon</label>
	<div class="input-group">
		<div class="input-group-prepend">
			<span class="input-group-text align-items-start"><i class="fas fa-pencil-alt"></i></span>
		</div>
		<textarea name="" class="form-control noresize" id="" cols="30" rows="5"></textarea>
	</div>
</div>

Checkboxes, radios and switches

Place any checkbox or radio option within an input group’s addon instead of text. 


<div class="input-group mb-3">
	<div class="input-group-prepend">
		<div class="input-group-text">
			<div class="custom-control custom-checkbox">
				<input type="checkbox" class="custom-control-input" id="checkbox1">
				<label class="custom-control-label" for="checkbox1"></label>
			</div>
		</div>
	</div>
	<input type="text" class="form-control" aria-label="Text input with checkbox" placeholder="Your input..">
</div>

<div class="input-group mb-3">
	<div class="input-group-prepend">
		<div class="input-group-text">
			<div class="custom-control custom-radio">
				<input id="radio1" name="radio" type="radio" class="custom-control-input">
				<label class="custom-control-label" for="radio1"></label>
			</div>
		</div>
	</div>
	<input type="text" class="form-control" aria-label="Text input with radio button" placeholder="Your input..">
</div>

<div class="input-group">
	<div class="input-group-prepend">
		<div class="input-group-text">
			<div class="custom-control custom-switch">
				<input id="checkbox2" name="checkbox" type="checkbox" class="custom-control-input">
				<label class="custom-control-label" for="checkbox2"></label>
			</div>

	</div>
	<input type="text" class="form-control" aria-label="Text input with switch" placeholder="Your input..">

Customizing input groups

Sizing

Add .input-group-sm or .input-group-lg to an .input-group to make it smaller or larger respectively. The contents within will automatically resize.

Small
Default
Large 

<div class="input-group input-group-sm mb-3">
	<div class="input-group-prepend">
		<span class="input-group-text" id="inputGroup-sizing-sm">Small</span>
	</div>
	<input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-sm">
</div>

<div class="input-group mb-3">
	<div class="input-group-prepend">
		<span class="input-group-text" id="inputGroup-sizing-default">Default</span>
	</div>
	<input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-default">
</div>

<div class="input-group input-group-lg">
	<div class="input-group-prepend">
		<span class="input-group-text" id="inputGroup-sizing-lg">Large</span>
	</div>
	<input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-lg">
</div>

Multiple addons

Multiple add-ons are supported and can be mixed with checkbox and radio input versions.
