Thank you for the fast reply.
There are no JS errors. The tabs are still not hidden.
A second thing is on an other conditional login first time load form. I have other fields that only should show up if the page is a child page. On first load of that page (OK on change of the page position as a child of…) they apear as they should but some of them should only be visible if a checkbox is clicked but they are visible on start. As it is with the tabs with a click on a chekcbox makes everything works well. On reload again the same issue.
I think it is because on first load or reload the hide class is not set. But why?
