支持以下 CSS 类

  • 标签
  • 输入
  • 文本区域
  • 选择
  • 复选框

field 容器是以下内容的简单容器

  • 文本 label
  • 表单 control
  • 可选 help 文本

示例

这是一个帮助文本

HTML 

<div class="field">

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

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">

  <div class="control">
    <input class="input" type="email" placeholder="e.g. [email protected]">
  </div>
</div>

表单控件 #

Bulma control 是一个通用的 块 容器，旨在 增强单个表单控件。因为它与它包装的元素具有相同的高度，所以它 只能包含 以下 Bulma 元素

  • 输入
  • 选择
  • 按钮
  • 图标

此容器提供以下功能

  • 保持 间距 一致
  • 将表单控件组合成一个 组
  • 将表单控件组合成一个 列表
  • 在表单控件中附加和插入 图标

示例

HTML 

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

示例

HTML 

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

示例

HTML 

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

带图标 #

您可以在控件上附加 2 个 修饰符 之一

  • has-icons-left
  • 和/或 has-icons-right

您还需要在 图标 上添加一个修饰符

  • 如果使用 has-icons-left，则为 icon is-left
  • 如果使用 has-icons-right，则为 icon is-right

输入 的大小将定义图标容器的大小。

示例

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>

您还可以将图标附加到 选择下拉框。

示例

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>

如果控件包含图标，Bulma 将确保图标保持 居中，无论输入大小 或 图标大小如何。

示例

HTML 

<div class="field">
  <label class="label is-small">Small input</label>
  <div class="control has-icons-left has-icons-right">

      <i class="fas fa-check fa-lg"></i>
    </span>
  </div>
</div>

表单附加项 #

如果您想将控件组合在一起，请对 field 容器使用 has-addons 修饰符

示例

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>

您只能附加输入、按钮和下拉菜单。

附加一个静态按钮可能很有用。

示例

@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>

对您想要填充剩余空间的元素（在本例中为输入）使用 is-expanded 修饰符

示例

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>

如果您想要一个全宽选择下拉菜单，请将 control is-expanded 与 select is-fullwidth 配对。

示例

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>

使用 has-addons-centered 或 has-addons-right 修饰符来更改对齐方式。

示例

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>

示例

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>

表单组 #

如果您想将控件组合在一起，请对 field 容器使用 is-grouped 修饰符。

示例

取消

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>

使用 is-grouped-centered 或 is-grouped-right 修饰符来更改对齐方式。

示例

取消

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>

示例

取消

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>

在您想要填充剩余空间的控件元素上添加 is-expanded 修饰符。

示例

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>

添加 is-grouped-multiline 修饰符以允许控件填充多行。这对于长控件列表来说是理想的。

示例

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">

  </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>
  </p>
  <p class="control">
    <button class="button">
      Thirteen
    </button>
  </p>
</div>

按钮列表

如果您只需要一个按钮列表，请尝试使用新的 buttons 类，您可以用它创建一个多行按钮列表。

水平表单 #

如果您想要一个水平表单控件，请对 field 容器使用 is-horizontal 修饰符，其中包括

  • field-label 作为侧标签
  • field-body 作为输入/选择/文本区域容器

您可以对子元素使用 is-grouped 或 has-addons。

示例

+44

不要输入第一个零

禁用表单 #

你可以通过将一组控件包装在带有 disabled HTML 属性的 fieldset 中来禁用部分或整个表单。

示例

HTML 

<fieldset disabled>
  
<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. [email protected]">
  </div>
</div>

</fieldset>
