Configuration Options

All settings have a default value, a data-skipto attribute on the script element or a global configuration object (e.g. SkipToConfig) can be used to change the default values and to localize the menu text to a specific language.

Options for adding the button element

The following options are useful for identify where the menu will be in the DOM structure of the page and which elements will be used as the container for the menu button. The options are of type string.

NOTE: The attachElement property is no longer supported due to scroll to content feature and the menu being in a fixed position at the top of the page.

Button Font Family and Font Size

Identifying Landmarks and Headings for the menu

The landmarks and ‘headings’ options are a space separated list of tag and landmark region names to identify the important landmark regions and headings on the page for the purpose of keyboard navigation. The list of landmarks and headings should be relatively short, the more items the menu contains the more time the user will need to scan and navigate to the section they want to “skip to”. The values are considered tokens to maximize compatibility with version 4 CSS selectors for these properties.

The options are of type string.

A color theme sets all the color options defined by the theme.

Current Color Theme Values:

• ‘aria’ : Used in ARIA Authoring practices

Example Settings

There are two ways for an author to configure SkipTo.js:

1. data-skipto attribute
2. Global variable

Settings Using Data Attribute

You can customize SkipTo.js to the features of your website by using a data-skipto attribute on the script element. Each property/value setting is separated by a semi-colon (;), and each property name and value is separated by a colon (:).

The following is a sample configuration:

<script
  data-skipto="landmarks: main search navigation; headings: h1 h2 h3; colorTheme: illinois"
  src="https://skipto-landmarks-headings.github.io/page-script-5/dist/skipto.min.js">
</script>

Settings Using Global Object

You can customize SkipTo.js to the features of your website by using a global object variable.

The following is a sample configuration:

<script>
  var SkipToConfig =  {
    landmarks: 'main search navigation',
    headings: 'h1 h2 h3',
    colorTheme: 'illinois'
  };
</script>

or

<script>
  window.SkipToConfig =  {};
  window.SkipToConfig.landmarks  = 'main search navigation';
  window.SkipToConfig.headings   = 'h1 h2 h3';
  window.SkipToConfig.colorTheme = 'illinois';
</script>

NOTE: Configuration objects in version 4.x are still supported for compatibility with existing installations. Version 5.x is providing a less complex object for customizing SkipTo.js.
