Hi Joseph Norris,

-–smart-accordion-item-header-height defaults to 48px everywhere in our code. The -–smart-accordion-expanded-content-height is 0 by design as it is automatically calculated when the control is created. If there is any sample which does not run, please point it out and we will check it. All the samples available online are using the latest version of the sources and styles.

Best regards,
