Installing

A set of Marko components implementing GOV.UK elements.

Installing

npm install govuk-elements-marko --save

Note: you will need to have the GOV.UK elements sass compiling in your service in order for the components to be styled correctly.

npm install govuk-elements-sass --save

Components

<gov-input/>

The <gov-input/> tag will render a standard GOV.UK input and label pair.

The input id will be set as 'input' followed by a dash and the input's name attribute.

For example:

<gov-input name='full-name' label='Full name'/>

Will produce the following markup:

<div class="form-group">
  <label for="input-full-name">
    <span class="form-label">Full name</span>
  </label>
  <input class="form-control" type="text" id="input-full-name" name="full-name"
    autocomplete="off">
</div>

Attributes

name - sets input name attribute (required)
label - sets label text (required)
hint - sets label hint text
group-classes - appends further classes <div class="form-group">
input-classes - appends further classes <input class="form-control">; eg. form-control-1-4 for quarter width.
id - override generated input id attribute
error - sets error message text
value - sets input value attribute
maxlength - sets input maxlength attribute
hide-label - adds visually-hidden to the input label (true/false)

<gov-date-input/>

<gov-date-input\> will generate the mark up for the GOV.UK date input pattern. It supports multiple name attribute formats to accommodate on your node body parser set up. It does not currently support separate error messages and highlighting per input.

The input ids are set as the input's name attribute followed by a dash and either 'day', 'month' or 'year', eg. birth-day, birth-month, etc. The format can be changed using the 'suffix' attribute, eg. suffix="camel" will produce name="birthDay" while suffix="object" will give name="birth[day]". Kebab case is default, name="birth-day".

Note: Day, month and year labels are currently hardcoded! Welsh is supported using the 'lang' attribute. It is also detected from the 'language' property of the express request object.

Example:

<gov-date-input name="date-of-birth" legend="What is your date of birth?"
  hint="For example, 31 3 1980"/>

Will produce the following markup:

<div class="form-group">
  <fieldset>
    <legend>
      <span class="form-label-bold">What is your date of birth?</span>
      <span id="date-of-birth-hint" class="form-hint">For example, 31 3 1980</span>
    </legend>
    <div class="form-date">
      <div class="form-group form-group-day">
        <label for="input-date-of-birth-day" class="form-label">Day</label>
        <input aria-describedby="date-of-birth-hint" class="form-control"
          id="input-date-of-birth-day" name="date-of-birth-day"
          pattern="[0-9]*" min="0" max="31" type="number"/>
      </div>
      <div class="form-group form-group-month">
        <label for="input-date-of-birth-month" class="form-label">Month</label>
        <input class="form-control" id="input-date-of-birth-month"
          name="date-of-birth-month" pattern="[0-9]*" min="0"
          max="12" type="number"/>
      </div>
      <div class="form-group form-group-year">
        <label for="input-date-of-birth-year" class="form-label">Year</label>
        <input class="form-control" id="input-date-of-birth-year"
          name="date-of-birth-year" pattern="[0-9]*" min="0"
          type="number"/>
      </div>

The input id will be set as 'checkbox' followed by a dash and the input's name attribute, eg. checkbox-cat.

Example:

<gov-checkbox label="I have a cat" name="cat" value="true"/>

Will produce the following mark up:

If you are implementing a one question per page pattern and wish to hide the legend, you can set the 'hide-legend' to true. This will add a 'visually-hidden' class.

      </span>
      <span class="body-text">
