Search Input

Search inputs allow users to input text, execute a search, and clear results. A search input may be used in conjunction with filters, sort, and/or auto-complete.

<script type="module">
  import '@brightspace-ui/core/components/inputs/input-search.js';
</script>
<d2l-input-search
  label="Search"
  value="Apples"
  placeholder="Search">
</d2l-input-search>

Best Practices

• Specify a label for the search input and include it as part of your design. (e.g. “Search Question Library”) This is typically hidden off-screen, but may be visible when warranted. Use your discretion.
• Add inline help to communicate when search is limited to specific facets. (e.g. “Search by question text or title”)
• Use “Search…” (ellipsis inclusive) for placeholder text to distinguish a search input from a straight-up text input.
• Place the search input in proximity to the content being searched. Best if directly above that content.
• Persist the search input on-screen if it is a primary or secondary action on the page. Otherwise consider a subtle button to trigger the search input.

• Don't use placeholder text as a label or to indicate which facets the search is limited to.
• Don't add a separate control for clearing search results. Use the “Clear Search” button in the search input.
• Don't rely on search as the only way for users to find things. There are other ways to support finding, including filters, categories, etc.

Search Input [d2l-input-search]

For text searches use <d2l-input-search>, which wraps the native <input type="search"> element.

<script type="module">
  import '@brightspace-ui/core/components/inputs/input-search.js';
</script>
<d2l-input-search label="Search">
</d2l-input-search>

Properties

Property	Type	Description
label	String, required	Acts as the primary label for the input. Not visible.
description	String	Additional information communicated to screenreader users when they focus on the input
disabled	Boolean	Disables the input
maxlength	Number	Imposes an upper character limit
no-clear	Boolean	Prevents the "clear" button from appearing
search-on-input	Boolean	Dispatch search events after each input event
placeholder	String, default:'Search...'	Placeholder text
value	String, default: ''	Value of the input

Events

The <d2l-input-search> component dispatches the d2l-input-search-searched event when a search is performed:

search.addEventListener('d2l-input-search-searched', (e) => {
  // e.detail.value contains the search value
  console.log(e.detail.value);
});

When the input is cleared, the same event will be fired with an empty value.

Slots

• inline-help: Help text that will appear below the input. Use this only when other helpful cues are not sufficient, such as a carefully-worded label.

Accessibility

• While the component does not have a visible label, the search icon clearly indicates its purpose
  • While not required to meet WCAG, this pattern is a great way to help individuals with cognitive accessibility needs
• It is important to note that placeholder is not a suitable replacement for label or description, since it only applies when the input is empty, and not all users will be able to read it in the first place
• Search results should be announced to screen reader users using a live region around the result summary or by using the announce helper
  • It can also be used to help confirm what exactly was searched, along with how many results were found
