Hi, I am trying to implement a single page cart.php, where users can add the product configurable options, see the order summary, provide billing address and place complete order all in a single page. Currently am using the standard WHMCS theme, and during each of the above mentioned activities the user goes to different pages and complete the order only after clicking continue button. For example, configure options will be added in ex.com/cart.php?a=add&pid=1 and on continue it will go to ex.com/cart.php?a=view. On the backed, there are separate tpl for each of these. Is there a way I can integrate all these into a single layout orlet me know if this feature is already available in WHMCS. Regards,
