Android Question MLMenu does not scroll

post the relevant code or upload small project thats shows the problem

I wanted to create a small example, but the MLMenu causes problems at the code:

mnu.Initialize(1, 40dip, Activity, Me, Colors.DarkGray, Colors.White, 18, "mnu")
mnu.AddMenuItem("1", Null)

My version: B4A V 6.80

My original app was created under V 4 (or older ???)

----------------------
its really hard to guess , how do you make the menu scroll? can you upload your project as zip ?

I found the source of MLMenu.bas. I removed the library from my project and instead I used the modul MLMenu.bas. Now it works also under B4A V 6.80.

I added 30 items to the menu.
If I show the menu with

mnu.OpenMenuAt(80%x, 0) I can scroll all 30 items.

But if I show the menu not from the top of the screen with

mnu.OpenMenuAt(80%x, 300) I can scroll only to item 26.

There must be an error in the MLMenu.bas.

try this code

tested on my device.. works fine

mnu.OpenMenuAt(80%x,0)

Yes, with top = 0 it works, but with e.g. top = 300 it doesn't work at my tablet.

I changed the code of MLMenu.bas so it works for me fine.
