Range Inputs

Set horizontally scrollable range inputs using .form-control-range.

<form><div class="form-group"><label for="formControlRange">Example Range input</label><input type="range" class="form-control-range" id="formControlRange"></div></form>
Checkboxes and radios

By default,any number of checkboxes and radios that are immediate sibling will be vertically stacked and appropriately spaced with .form-check.

<div class="form-check"><input class="form-check-input" type="checkbox" value="" id="defaultCheck1"><label class="form-check-label" for="defaultCheck1">Default checkbox </label></div><div class="form-check"><input class="form-check-input" type="checkbox" value="" id="defaultCheck2" disabled><label class="form-check-label" for="defaultCheck2">Disabled checkbox </label></div>
<div class="form-check"><input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios1" value="option1" checked><label class="form-check-label" for="exampleRadios1">Default radio </label></div><div class="form-check"><input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios2" value="option2"><label class="form-check-label" for="exampleRadios2">Second default radio </label></div><div class="form-check"><input class="form-check-input" type="radio" name="exampleRadios" id="exampleRadios3" value="option3" disabled><label class="form-check-label" for="exampleRadios3">Disabled radio </label></div>

Inline

Group checkboxes or radios on the same horizontal row by adding .form-check-inline to any .form-check.

<div class="form-check form-check-inline"><input class="form-check-input" type="checkbox" id="inlineCheckbox1" value="option1"><label class="form-check-label" for="inlineCheckbox1">1</label></div><div class="form-check form-check-inline"><input class="form-check-input" type="checkbox" id="inlineCheckbox2" value="option2"><label class="form-check-label" for="inlineCheckbox2">2</label></div><div class="form-check form-check-inline"><input class="form-check-input" type="checkbox" id="inlineCheckbox3" value="option3" disabled><label class="form-check-label" for="inlineCheckbox3">3(disabled)</label></div>
<div class="form-check form-check-inline"><input class="form-check-input" type="checkbox" id="inlineCheckbox1" value="option1"><label class="form-check-label" for="inlineCheckbox1">1</label></div><div class="form-check form-check-inline"><input class="form-check-input" type="checkbox" id="inlineCheckbox2" value="option2"><label class="form-check-label" for="inlineCheckbox2">2</label></div><div class="form-check form-check-inline"><input class="form-check-input" type="checkbox" id="inlineCheckbox3" value="option3" disabled><label class="form-check-label" for="inlineCheckbox3">3(disabled)</label></div>

Without labels

Add .position-staticto inputs within .form-checkthat don’t have any label text. Remember to still provide some form of label for assistive technologies(for instance,using aria-label).

<div class="form-check"><input class="form-check-input position-static" type="checkbox" id="blankCheckbox" value="option1" aria-label="..."></div><div class="form-check"><input class="form-check-input position-static" type="radio" name="blankRadio" id="blankRadio1" value="option1" aria-label="..."></div>
Layout

Form row

You may also swap .rowfor .form-row,a variation of our standard grid row that overrides the default column gutters for tighter and more compact layouts.

<form><div class="form-row"><div class="col"><input type="text" class="form-control" placeholder="First name"></div><div class="col"><input type="text" class="form-control" placeholder="Last name"></div></div></form>

More complex layouts can also be created with the grid system.

<form><div class="form-row"><div class="form-group col-md-6"><label for="inputEmail4">Email</label><input type="email" class="form-control" id="inputEmail4" placeholder="Email"></div><div class="form-group col-md-6"><label for="inputPassword4">Password</label><input type="password" class="form-control" id="inputPassword4" placeholder="Password"></div></div><div class="form-group"><label for="inputAddress">Address</label><input type="text" class="form-control" id="inputAddress" placeholder="1234 Main St"></div><div class="form-group"><label for="inputAddress2">Address 2</label><input type="text" class="form-control" id="inputAddress2" placeholder="Apartment, studio, or floor"></div><div class="form-row"><div class="form-group col-md-6"><label for="inputCity">City</label><input type="text" class="form-control" id="inputCity"></div><div class="form-group col-md-4"><label for="inputState">State</label><select id="inputState" class="form-control"><option selected>Choose...</option><option>...</option></select></div><div class="form-group col-md-2"><label for="inputZip">Zip</label><input type="text" class="form-control" id="inputZip"></div></div><div class="form-group"><div class="form-check"><input class="form-check-input" type="checkbox" id="gridCheck"><label class="form-check-label" for="gridCheck">Check me out </label></div></div><button type="submit" class="btn btn-primary">Sign in</button></form>

Horizontal form label sizing

Be sure to use .col-form-label-smor .col-form-label-lgto your <label>s or <label>s to correctly follow the size of .form-control-lgand .form-control-sm.

<form><div class="form-group row"><label for="colFormLabelSm" class="col-sm-2 col-form-label col-form-label-sm">Email</label><div class="col-sm-10"><input type="email" class="form-control form-control-sm" id="colFormLabelSm" placeholder="col-form-label-sm"></div></div><div class="form-group row"><label for="colFormLabel" class="col-sm-2 col-form-label">Email</label><div class="col-sm-10"><input type="email" class="form-control" id="colFormLabel" placeholder="col-form-label"></div></div><div class="form-group row"><label for="colFormLabelLg" class="col-sm-2 col-form-label col-form-label-lg">Email</label><div class="col-sm-10"><input type="email" class="form-control form-control-lg" id="colFormLabelLg" placeholder="col-form-label-lg"></div></div></form>
Help text

Block-level help text in forms can be created using .form-text(previously known as .help-blockin v3). Inline help text can be flexibly implemented using any inline HTML element and utility classes like .text-muted.

Your password must be 8-20 characters long,contain letters and numbers,and must not contain spaces,special characters,or emoji. 
<label for="inputPassword5">Password</label><input type="password" id="inputPassword5" class="form-control" aria-describedby="passwordHelpBlock"><small id="passwordHelpBlock" class="form-text text-muted">Your password must be 8-20 characters long,contain letters and numbers,and must not contain spaces,special characters,or emoji. </small>
