Hello there,
I made menu and I’m proud on it 
Now, I want when player clicks drop button, widget pops up with box that says
" You have xx of xx
How many do you want to throw ? " and after that I want to place box or something that have max value same as number of items in stack made in other graph.
long story short, how to make box that player can fill but max value is as above mentioned, number of items in stack. Is there a way to make that with combobox ?
That’s not a combo box, a combo box is a dropdown list of strings. What you need is a Spin Box, it has variables for minimum and maximum number entrys
