A web component for navigating to sections of your page that can stick as you scroll.

import "../../node_modules/@bitovi/scrolling-nav";
To use, just insert the HTML element tag created by the package.

That's it.
You can optionally provide attributes to the component to customize your experience. Here are the default attribute values.
<scrolling-nav
scrollable-container-selector="window"
heading-selector="h2"
></scrolling-nav>
falsestring"window"The scrollable-container-selector attribute is the tag (HTML element, class, or ID) contains the section headings that you want to scroll to. By default, it will be the window.
<scrolling-nav scrollable-container-selector=".header"></scrolling-nav>
falsestring"h2"The heading-selector attribute is the tag (HTML element, class, or ID) that will be used to create the navbar items. By default, it will scour the <body> for H2 tags.
<scrolling-nav heading-selector="h3"><scrolling-nav>
You can override or modify the default styles by using the provided IDs and classes. The component is structured like the following:
<scrolling-nav>
<ul class="scrolling-nav-inner">
...
<ul class="scrolling-nav-item">
<a>Heading Example 1</a>
</ul>
...
<ul class="scrolling-nav-item">
<a>Heading Example 2</a>
</ul>
...
</div>
</scrolling-nav>
To customize the styles of the navbar container, use the following tag in your styles:
scrolling-nav {}
To customize the styles of the navbar inner container (which is scrolled by the outer container), use the following ID in your styles:
scrolling-nav > ul {}
To customize the styles of the navbar's items, use the following class in your styles:
scrolling-nav > ul > li {}
If you want to customize the active state of a nav item, use the following class in your styles:
scrolling-nav > ul > li.scrolling-nav-active {}
The scrolling-nav-active class is added whenever the section represented by the nav item is in or below the top 1/3 of the page and above of the next section in the page. The scrolling-nav-active class will only be applied to one item at a time.
You may get the following linting error on the web component: Property 'scrolling-nav' does not exist on type 'JSX.IntrinsicElements'. To fix this, add the following snippet to your declarations.d.ts file.
// In ~/declarations.d.ts
declare namespace JSX {
// ...
interface IntrinsicElements {
// ...
"scrolling-nav": any;
}
}
