I hope this message finds you well. I would like to bring to your attention an issue we have identified regarding the validation of required fields when using tabs in Seblod CCK.

We have recently encountered a problem where the validation of required fields only functions correctly when all required fields are displayed on a single page, rather than distributed across multiple tabs. It's worth noting that this problem did not exist with Seblod version 3.x and Joomla 3.x.

When required fields are distributed across multiple tabs, the validation does not occur as expected, potentially leading to incomplete or incorrect data in our applications.
