Hi @Krapicz Balazs Istvan ,
You want to realize that when the value of "Szegmens" is "Vállalati", the other three columns are not displayed.
Here are steps(Execute each column that needs to be hidden):
1.In the Edit columns pane
2.Select the far right hand edge of the "Születési idő" column to display the options menu (...), select Edit conditional formula.
3.Enter formula:
=if([$Szegmens] == 'VÁLLALATI', 'false', 'true')
For more detail information:Show or hide columns in a list or library form
