Design patterns that serve as basic building blocks.
Easily extend form controls by adding text, buttons, or button groups on either side of textual <input>s.
Place one add-on or button on either side of an input. You may also place one on both sides of an input. We do not support multiple form-controls in a single input group.
<div class="input-group">
<span class="input-group-addon" id="basic-addon1">@</span>
<input type="text" class="form-control" placeholder="Username" aria-describedby="basic-addon1">
</div>
<br>
<div class="input-group">
<input type="text" class="form-control" placeholder="Recipient's username" aria-describedby="basic-addon2">
<span class="input-group-addon" id="basic-addon2">@example.com</span>
</div>
<br>
<label for="basic-url">Your vanity URL</label>
<div class="input-group">
<span class="input-group-addon" id="basic-addon3">https://example.com/users/</span>
<input type="text" class="form-control" id="basic-url" aria-describedby="basic-addon3">
</div>
<br>
<div class="input-group">
<span class="input-group-addon">$</span>
<input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
<span class="input-group-addon">.00</span>
</div>
<br>
<div class="input-group">
<span class="input-group-addon">$</span>
<span class="input-group-addon">0.00</span>
<input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
</div>Add the relative form sizing classes to the .input-group itself and contents within will automatically resize—no need for repeating the form control size classes on each element.
<div class="input-group input-group-lg">
<span class="input-group-addon" id="sizing-addon1">@</span>
<input type="text" class="form-control" placeholder="Username" aria-describedby="sizing-addon1">
</div>
<br>
<div class="input-group">
<span class="input-group-addon" id="sizing-addon2">@</span>
<input type="text" class="form-control" placeholder="Username" aria-describedby="sizing-addon2">
</div>Place any checkbox or radio option within an input group’s addon instead of text.
<div class="input-group">
<span class="input-group-addon">
<input type="checkbox" aria-label="Checkbox for following text input">
</span>
<input type="text" class="form-control" aria-label="Text input with checkbox">
</div>
<div class="input-group">
<span class="input-group-addon">
<input type="radio" aria-label="Radio button for following text input">
</span>
<input type="text" class="form-control" aria-label="Text input with radio button">
</div>Multiple add-ons are supported and can be mixed with checkbox and radio input versions.
<div class="input-group">
<span class="input-group-addon">
<input type="checkbox" aria-label="Checkbox for following text input">
</span>
<span class="input-group-addon">$</span>
<input type="text" class="form-control" aria-label="Text input with checkbox">
</div>
<div class="input-group">
<span class="input-group-addon">$</span>
<span class="input-group-addon">0.00</span>
<input type="text" class="form-control" aria-label="Text input with radio button">
</div>Buttons in input groups are a bit different and require one extra level of nesting. Instead of .input-group-addon, you’ll need to use .input-group-btn to wrap the buttons. This is required due to default browser styles that cannot be overridden.
<div class="input-group">
<span class="input-group-btn">
<button class="btn btn-secondary" type="button">Go!</button>
</span>
<input type="text" class="form-control" placeholder="Search for...">
</div>
<div class="input-group">
<input type="text" class="form-control" placeholder="Search for...">
<span class="input-group-btn">
<button class="btn btn-secondary" type="button">Go!</button>
</span>
</div>
<div class="input-group">
<span class="input-group-btn">
<button class="btn btn-secondary" type="button">Hate it</button>
</span>
<input type="text" class="form-control" placeholder="Product name">
<span class="input-group-btn">
<button class="btn btn-secondary" type="button">Love it</button>
</span>
</div>Inputs can also be placed in headers, along with buttons to submit or cancel the form.
<header class="bar bar-nav">
<div class="input-group input-group-inset">
<span class="input-group-placeholder icon icon-search"></span>
<input type="search" class="form-control" placeholder="Search">
<span class="input-group-btn">
<button class="btn btn-link" type="button">Cancel</button>
</span>
</div>
</header>Screen readers will have trouble with your forms if you don’t include a label for every input. For these input groups, ensure that any additional label or functionality is conveyed to assistive technologies.
The exact technique to be used (<label> elements hidden using the .sr-only class, or use of the aria-label, aria-labelledby, aria-describedby, title or placeholder attribute) and what additional information will need to be conveyed will vary depending on the exact type of interface widget you’re implementing. The examples in this section provide a few suggested, case-specific approaches.
