Form controls

常用的表单组件

Bulma supports the following native HTML form elements: <form> <button> <input> <textarea> and <label>.

The following CSS classes are supported:

  • label
  • input
  • textarea
  • select
  • checkbox
  • radio
  • button
  • help

To maintain an evenly balanced design, Bulma provides a very useful control container with which you can wrap the form controls.
When combining several controls in a form, use the field class as a container, to keep the spacing consistent.

<div class="field">
  <div class="control">

    <button class="button is-link">Submit</button>
  </div>
  <div class="control">
    <button class="button is-link is-light">Cancel</button>
  </div>
</div>

For the best results using Bulma, it's recommended to use the control element as often as possible.

Form field #

The field container is a simple container for:

  • a text label
  • a form control
  • an optional helptext

Example

This is a help text

HTML 

<div class="field">
  <label class="label">Label</label>
  <div class="control">
    <input class="input" type="text" placeholder="Text input">
  </div>
  <p class="help">This is a help text</p>
</div>

This container allows form fields to be spaced consistently.

Example

HTML 

<div class="field">
  <label class="label">Name</label>
  <div class="control">
    <input class="input" type="text" placeholder="e.g Alex Smith">
  </div>
</div>

<div class="field">
  <label class="label">Email</label>
  <div class="control">
    <input class="input" type="email" placeholder="e.g. alexsmith@gmail.com">
  </div>
</div>

Form control #

The Bulma control is a versatile block container meant to enhance single form controls. Because it has the same height as the element that it wraps, it can only contain the following Bulma elements:

  • input
  • select
  • button
  • icon

This container gives the ability to:

  • keep the spacing consistent
  • combine form controls into a group
  • combine form controls into a list
  • append and prepend icons to a form control

Example

HTML 

<div class="control">
  <input class="input" type="text" placeholder="Text input">
</div>

Example

HTML 

<div class="control">
  <div class="select">
    <select>
      <option>Select dropdown</option>
      <option>With options</option>
    </select>
  </div>
</div>

Example

HTML 

<div class="control">
  <button class="button is-primary">Submit</button>
</div>

With icons #

You can append one of 2 modifiers on a control:

  • has-icons-left
  • and/or has-icons-right

You also need to add a modifier on the icon:

  • icon is-left if has-icons-left is used
  • icon is-right if has-icons-right is used

The size of the input will define the size of the icon container.

Example

HTML 

<div class="field">
  <p class="control has-icons-left has-icons-right">
    <input class="input" type="email" placeholder="Email">
    <span class="icon is-small is-left">
      <i class="fas fa-envelope"></i>
    </span>
    <span class="icon is-small is-right">
      <i class="fas fa-check"></i>
    </span>
  </p>
</div>
<div class="field">
  <p class="control has-icons-left">
    <input class="input" type="password" placeholder="Password">
    <span class="icon is-small is-left">
      <i class="fas fa-lock"></i>
    </span>
  </p>
</div>
<div class="field">
  <p class="control">
    <button class="button is-success">
      Login
    </button>
  </p>
</div>

You can append icons to select dropdowns as well.

Example

HTML 

<div class="field">
  <p class="control has-icons-left">
    <span class="select">
      <select>
        <option selected>Country</option>
        <option>Select dropdown</option>
        <option>With options</option>
      </select>
    </span>
    <span class="icon is-small is-left">
      <i class="fas fa-globe"></i>
    </span>
  </p>
</div>

If the control contains an icon, Bulma will make sure the icon remains centered, no matter the size of the input or of the icon.

Example

HTML 

<div class="field">
  <label class="label is-small">Small input</label>
  <div class="control has-icons-left has-icons-right">
    <input class="input is-small" type="email" placeholder="Normal">
    <span class="icon is-small is-left">
      <i class="fas fa-envelope"></i>
    </span>
    <span class="icon is-small is-right">
      <i class="fas fa-check"></i>
    </span>
  </div>
</div>

Example

HTML 

<div class="field">
  <label class="label">Normal input</label>
  <div class="control has-icons-left has-icons-right">
    <input class="input" type="email" placeholder="Extra small">
    <span class="icon is-small is-left">
      <i class="fas fa-envelope fa-xs"></i>
    </span>
    <span class="icon is-small is-right">
      <i class="fas fa-check fa-xs"></i>
    </span>
  </div>
</div>

<div class="field">
  <div class="control has-icons-left has-icons-right">
    <input class="input" type="email" placeholder="Normal">
    <span class="icon is-left">
      <i class="fas fa-envelope"></i>
    </span>
    <span class="icon is-right">
      <i class="fas fa-check"></i>
    </span>
  </div>
</div>

Example

HTML 

<div class="field">
  <label class="label is-medium">Medium input</label>
  <div class="control has-icons-left has-icons-right">
    <input class="input is-medium" type="email" placeholder="Extra small">
    <span class="icon is-small is-left">
      <i class="fas fa-envelope fa-xs"></i>
    </span>
    <span class="icon is-small is-right">
      <i class="fas fa-check fa-xs"></i>
    </span>
  </div>
</div>

<div class="field">
  <div class="control has-icons-left has-icons-right">
    <input class="input is-medium" type="email" placeholder="Small">
    <span class="icon is-left">
      <i class="fas fa-envelope fa-sm"></i>
    </span>
    <span class="icon is-right">
      <i class="fas fa-check fa-sm"></i>
    </span>
  </div>
</div>

    </span>
    <span class="icon is-medium is-right">
      <i class="fas fa-check"></i>
    </span>

</div>

Example

HTML 

<div class="field">
  <label class="label is-large">Large input</label>
  <div class="control has-icons-left has-icons-right">
    <input class="input is-large" type="email" placeholder="Extra small">
    <span class="icon is-small is-left">
      <i class="fas fa-envelope fa-xs"></i>
    </span>
    <span class="icon is-small is-right">
      <i class="fas fa-check fa-xs"></i>
    </span>
  </div>
</div>

<div class="field">
  <div class="control has-icons-left has-icons-right">
    <input class="input is-large" type="email" placeholder="Small">
    <span class="icon is-left">
      <i class="fas fa-envelope fa-sm"></i>
    </span>
    <span class="icon is-right">
      <i class="fas fa-check fa-sm"></i>
    </span>
  </div>
</div>

<div class="field">
  <div class="control has-icons-left has-icons-right">
    <input class="input is-large" type="email" placeholder="Normal">
    <span class="icon is-large is-left">
      <i class="fas fa-envelope"></i>
    </span>
    <span class="icon is-large is-right">
      <i class="fas fa-check"></i>
    </span>

</div>

<div class="field">
  <div class="control has-icons-left has-icons-right">
    <input class="input is-large" type="email" placeholder="Large">
    <span class="icon is-medium is-left">
      <i class="fas fa-envelope fa-lg"></i>
    </span>
    <span class="icon is-medium is-right">
      <i class="fas fa-check fa-lg"></i>
    </span>
  </div>
</div>

Form addons #

If you want to attach controls together, use the has-addons modifier on the field container:

Example

HTML 

<div class="field has-addons">
  <div class="control">
    <input class="input" type="text" placeholder="Find a repository">
  </div>
  <div class="control">
    <button class="button is-info">
      Search
    </button>
  </div>
</div>

You can attach inputs, buttons, and dropdowns only.

It can be useful to append a static button.

Example

@gmail.com

HTML 

<div class="field has-addons">
  <p class="control">
    <input class="input" type="text" placeholder="Your email">
  </p>
  <p class="control">
    <a class="button is-static">
      @gmail.com
    </a>
  </p>
</div>

Use the is-expanded modifier on the element you want to fill up the remaining space (in this case, the input):

Example

HTML 

<div class="field has-addons">
  <p class="control">
    <span class="select">
      <select>
        <option>$</option>
        <option>£</option>
        <option>€</option>
      </select>
    </span>
  </p>
  <p class="control">
    <input class="input" type="text" placeholder="Amount of money">
  </p>
  <p class="control">
    <button class="button">
      Transfer
    </button>
  </p>
</div>

<div class="field has-addons">
  <p class="control">
    <span class="select">
      <select>
        <option>$</option>
        <option>£</option>
        <option>€</option>
      </select>
    </span>
  </p>
  <p class="control is-expanded">
    <input class="input" type="text" placeholder="Amount of money">
  </p>
  <p class="control">
    <button class="button">
      Transfer
    </button>
  </p>
</div>

If you want a full width select dropdown, pair control is-expanded with select is-fullwidth.

Example

HTML 

<div class="field has-addons">
  <div class="control is-expanded">
    <div class="select is-fullwidth">
      <select name="country">
        <option value="Argentina">Argentina</option>
        <option value="Bolivia">Bolivia</option>
        <option value="Brazil">Brazil</option>
        <option value="Chile">Chile</option>
        <option value="Colombia">Colombia</option>
        <option value="Ecuador">Ecuador</option>
        <option value="Guyana">Guyana</option>
        <option value="Paraguay">Paraguay</option>
        <option value="Peru">Peru</option>
        <option value="Suriname">Suriname</option>
        <option value="Uruguay">Uruguay</option>
        <option value="Venezuela">Venezuela</option>
      </select>
    </div>
  </div>
  <div class="control">
    <button type="submit" class="button is-primary">Choose</button>
  </div>
</div>

Use the has-addons-centered or the has-addons-right modifiers to alter the alignment.

Example

HTML 

<div class="field has-addons has-addons-centered">
  <p class="control">
    <span class="select">
      <select>
        <option>$</option>
        <option>£</option>
        <option>€</option>
      </select>
    </span>
  </p>
  <p class="control">
    <input class="input" type="text" placeholder="Amount of money">
  </p>
  <p class="control">
    <button class="button is-primary">
      Transfer
    </button>
  </p>
</div>

Example

HTML 

<div class="field has-addons has-addons-right">
  <p class="control">
    <span class="select">
      <select>
        <option>$</option>
        <option>£</option>
        <option>€</option>
      </select>
    </span>
  </p>
  <p class="control">
    <input class="input" type="text" placeholder="Amount of money">
  </p>
  <p class="control">
    <button class="button is-primary">
      Transfer
    </button>
  </p>
</div>

Form group #

If you want to group controls together, use the is-grouped modifier on the field container.

Example

Cancel

HTML 

<div class="field is-grouped">
  <p class="control">
    <button class="button is-primary">
      Submit
    </button>
  </p>
  <p class="control">
    <a class="button is-light">
      Cancel
    </a>
  </p>
</div>

Use the is-grouped-centered or the is-grouped-right modifiers to alter the alignment.

Example

Cancel

HTML 

<div class="field is-grouped is-grouped-centered">
  <p class="control">
    <button class="button is-primary">
      Submit
    </button>
  </p>
  <p class="control">
    <a class="button is-light">
      Cancel
    </a>
  </p>
</div>

Example

Cancel

HTML 

<div class="field is-grouped is-grouped-right">
  <p class="control">
    <button class="button is-primary">
      Submit
    </button>
  </p>
  <p class="control">
    <a class="button is-light">
      Cancel
    </a>
  </p>
</div>

Add the is-expanded modifier on the control element you want to fill up the remaining space with.

Example

HTML 

<div class="field is-grouped">
  <p class="control is-expanded">
    <input class="input" type="text" placeholder="Find a repository">
  </p>
  <p class="control">
    <button class="button is-info">
      Search
    </button>
  </p>
</div>

Add the is-grouped-multiline modifier to allow controls to fill up multiple lines. This is ideal for a long list of controls.

Example

HTML 

<div class="field is-grouped is-grouped-multiline">
  <p class="control">
    <button class="button">
      One
    </button>
  </p>
  <p class="control">
    <button class="button">
      Two
    </button>
  </p>
  <p class="control">
    <button class="button">
      Three
    </button>
  </p>
  <p class="control">
    <button class="button">
      Four
    </button>
  </p>
  <p class="control">
    <button class="button">
      Five
    </button>
  </p>
  <p class="control">
    <button class="button">
      Six
    </button>
  </p>
  <p class="control">
    <button class="button">
      Seven
    </button>
  </p>
  <p class="control">
    <button class="button">
      Eight
    </button>
  </p>
  <p class="control">
    <button class="button">
      Nine
    </button>
  </p>
  <p class="control">
    <button class="button">
      Ten
    </button>
  </p>
  <p class="control">
    <button class="button">
      Eleven
    </button>
  </p>
  <p class="control">
    <button class="button">
      Twelve
    </button>
  </p>
  <p class="control">
    <button class="button">
      Thirteen
    </button>
  </p>
</div>

List of buttons

If you only need a list of buttons, try out the new buttons class with which you can create a multiline list of buttons.

Horizontal form #

If you want a horizontal form control, use the is-horizontal modifier on the field container, in which you include:

  • field-label for the side label
  • field-body for the input/select/textarea container

You can use is-grouped or has-addons for the child elements.

Example

+44

Do not enter the first zero

This field is required

To preserve the vertical alignment of labels with each type and size of control, the field-label comes with 4 size modifiers:

  • is-small
  • is-normal for any input or button
  • is-medium
  • is-large
