“Sticky” Table of Contents (TOC) Widget)

sorry, no not at this time.

Hi @steven,

can we make a sticky easy toc?

/* 1. Enable smooth scrolling */
html {
scroll-behavior: smooth;
}

/* 2. Make nav sticky */
main > nav {
position: sticky;
top: 2rem;
align-self: start;
}

/* 3. ScrollSpy active styles (see JS tab for activation) */
.section-nav li.active > a {
color: #333;
font-weight: 500;
}

/* Sidebar Navigation */
.section-nav {
padding-left: 0;
border-left: 1px solid #efefef;
}

.section-nav a {
text-decoration: none;
display: block;
padding: .125rem 0;
color: #ccc;
transition: all 50ms ease-in-out; /* ?? This small transition makes setting of the active state smooth */
}

.section-nav a:hover,
.section-nav a:focus {
color: #666;
}

/** Poor man’s reset **/
* {
box-sizing: border-box;
}

html, body {
background: #fff;
}

body {
font-family: -apple-system, BlinkMacSystemFont, “Segoe UI”, “Roboto”, “Oxygen”, “Ubuntu”, “Cantarell”, “Fira Sans”, “Droid Sans”, “Helvetica Neue”, sans-serif;
}

ul, ol {
list-style: none;
margin: 0;
padding: 0;
}
li {
margin-left: 1rem;
}

h1 {
font-weight: 300;
}

/** page layout **/
main {
display: grid;
grid-template-columns: 1fr 15em;
max-width: 100em;
width: 90%;
margin: 0 auto;
}

/** enlarge the sections for this demo, so that we have a long scrollable page **/
section {
padding-bottom: 20rem;
}

window.addEventListener(‘DOMContentLoaded’, () => {

const observer = new IntersectionObserver(entries => {
entries.forEach(entry => {
const id = entry.target.getAttribute(‘id’);
if (entry.intersectionRatio > 0) {
document.querySelector(nav li a[href="#${id}"]).parentElement.classList.add(‘active’);
} else {
document.querySelector(nav li a[href="#${id}"]).parentElement.classList.remove(‘active’);
}
});
});

// Track all sections that have an id applied
document.querySelectorAll(‘section[id]’).forEach((section) => {
observer.observe(section);
});

});
