How to update value in a menu item on runtime?

You can update the value of an ItemInput in the loop function by calling menu.getItemAt(``position``)->setValue("your new value here")

Examples:

1. menu.getItemAt(``your position``)->setValue("your new value here")

2. menu[``your position``]->setValue("your new value here")

3. menu[``your position``][``your sub position``].setValue("your new value here")

1. and 2. are the same, 3. will change the value of the item at ``your sub position`` in the submenu at ``your position``

You can also use [menu.getCursorPosition()] in place of menu.[``your position``] if your cursor is on your desired menu item.

Index/position starts from 1
