Change tab order of fields on custom form

@info87066 Hi,
please do the following steps:
in the editor in the section where all these fields are, at go to the first field that should be tabbed select it and in the floating menu click the three dots,
then go to arrange and select bring to front, then go to the second in the order that you want and do the same → bring to front, and so on and so on until the last one.

Lmk if this works.
