To add third button to Promotional Popup in Squarespace.
Like this.
You can use this code to Code Injection > Footer
<script>
const newItems = [
{text: 'Services', url: '/services'},
{text: 'About', url: '/about'}
];
const addNavItems = () => {
const interval = setInterval(() => {
const ul = document.querySelector('[data-compound-type="popup-overlay-action"] ul');
if (ul) {
newItems.forEach(item => {
const li = document.createElement('li');
const a = document.createElement('a');
a.href = item.url;
a.textContent = item.text;
li.appendChild(a);
ul.insertBefore(li, ul.firstChild);
});
clearInterval(interval);
}
}, 100);
};
addNavItems();
</script>
You can change text/url here.
