Which embed style when?
Button
The classic. Great for landing pages, hero sections and "Sign up now" CTAs. Clicking opens a chooser for the visitor's calendar.
Dropdown
Compact: the button IS the dropdown. On click the calendar chooser is immediately visible. Good for footers, sidebars or long pages.
Link
A plain text link with no styling — fits inline text, blog posts, or newsletter signatures.
Optimized for email clients (Outlook, Apple Mail, Gmail). Because many clients block JS, we use static per-calendar links here.
