表单控件

所有通用表单控件，设计用于一致性

Bulma 支持以下原生 HTML 表单元素: <form> <button> <input> <textarea> 和 <label>。

支持以下 CSS 类

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

为了保持均匀平衡的设计，Bulma 提供了一个非常有用的 control 容器，您可以使用它来包裹表单控件。
当在一个 form 中组合多个控件时，使用 field 类作为容器，以保持间距一致。

HTML 

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

<div class="field">
  <label class="label">Username</label>
  <div class="control has-icons-left has-icons-right">
    <input class="input is-success" type="text" placeholder="Text input" value="bulma">
    <span class="icon is-small is-left">
      <i class="fas fa-user"></i>

      <i class="fas fa-check"></i>
    </span>
  </div>
  <p class="help is-success">This username is available</p>
</div>

<div class="field">
  <label class="label">Email</label>
  <div class="control has-icons-left has-icons-right">
    <input class="input is-danger" type="email" placeholder="Email input" value="hello@">
    <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-exclamation-triangle"></i>

  </div>
  <p class="help is-danger">This email is invalid</p>
</div>

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

<div class="field">
  <label class="label">Message</label>
  <div class="control">
    <textarea class="textarea" placeholder="Textarea"></textarea>
  </div>
</div>

<div class="field">
  <div class="control">
    <label class="checkbox">
      <input type="checkbox">
      I agree to the <a href="#">terms and conditions</a>
    </label>
  </div>
</div>

<div class="field">
  <div class="control">
    <label class="radio">
      <input type="radio" name="question">
      Yes
    </label>
    <label class="radio">
      <input type="radio" name="question">

  </div>
</div>

<div class="field is-grouped">
  <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>

为了获得使用 Bulma 的最佳效果，建议尽可能多地使用 control 元素。

表单字段 #

field 容器是一个简单的容器，用于

  • 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">
  <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>

此容器允许表单字段保持一致的间距。

示例

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. [email protected]">
  </div>
</div>

表单控件 #

Bulma control 是一个通用的 块级 容器，旨在增强单个表单控件。 因为它与其包裹的元素具有相同的高度，所以它只能包含以下 Bulma 元素

  • input
  • select
  • button
  • icon

此容器提供以下功能：

  • 保持间距一致
  • 将表单控件组合成组
  • 将表单控件组合成列表
  • 在表单控件中添加和前置图标

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>

使用图标 #

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 icon 上添加一个修饰符

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

确保输入框是控件的第一个子元素，否则选中时图标可能会消失。input 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>

您也可以将图标附加到 选择下拉菜单。

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，无论输入框或图标的大小如何。

示例

HTML 

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

示例

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>

表单插件 #

如果您想将控件附加在一起，请在 field 容器上使用 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>

您可以附加输入框、按钮和下拉菜单仅限。

附加 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>

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

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>

如果您想要全宽的选择下拉菜单，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 #

如果您想将控件分组在一起，请在 field 容器上使用 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 control 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。 这对于长的控件列表非常理想。

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">
      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>

按钮列表

如果您只需要一个 按钮 列表，请尝试新的 buttons 类，您可以使用它来创建一个 多行按钮列表。

水平表单 #

如果您想要一个 水平 表单控件，请在 field 容器上使用 is-horizontal 修饰符，其中包含

  • 侧边标签的 field-label
  • 输入框/选择框/文本区域容器的 field-body

您可以为子元素使用 is-grouped 或 has-addons。

示例

+44

不要输入第一个零

此字段为必填项
