Check the number of selectable checkboxes

Hello,
I have a select where based on the chosen number I show checkboxes.
However, these can only be selected based on the choice of select

Example.
Select value

2
3

Checkbox

Is i select in select 2

I have to prevent more than 2 checkboxes from being selected, what can I do?
