Particular items are shown based on a dropdown selection

[mathieuv]

Hi everyone,

As illustration, I have added an excel document in attachment: example.xlsx
I have made a drop down list. It would be nice that if you select a certain sales employee (or sales manager, ...), then only the customers of this particular sales employee (or sales maanger) are visible in the list.

Someone has an idea how to do that?

Many thanks for your advice,
Best regards,
Mathieu
