Why does my DropDownMenu not Work
I wonder why my dropdown Menu is not working. I want it in an extern js not in the html. How it should work: if you choose like "2. Semester" in the second dropdown should be just possible to chose "Modul 5" - "Modul 8" if you choose "3.Semester" than it should be just possible to choose "Modul 9"-"Modul 12" in the second dropdown THis is the code: https://code.sololearn.com/WfCHRCweyms8

Remember to not get reference of elements (like using getElementById and similar) BEFORE element is loaded... See here for a better understanding

Start with adjust how declare your array (you missed many ',' between elements like [[1,2,3],[2,3,4],...)

@KrOW hey Im not sure why the moduls are not shown. Cause the eventlisener is in the onload method that meens all elements are loaded.
but why the function medulSet get not activated after selection?
