+## Usage on links
+
+<span class="badge badge-info small">2.15.0+</span>
+
+If placing the directive on a link (or a component that renders a link), the target ID can
+alternatively be specified via the `href` attribute.
+
+Note that the browser URL will change and the page may scroll the target into view. To prevent the
+URL from changing and the page from scrolling, add `@click.prevent` to the link.
+
+**Example usage:**
+
+```html
+<template>
+  <div>
+    <div class="mb-3">
+      <a v-b-toggle href="#example-collapse" @click.prevent>Toggle Collapse</a>
