Good Morning Oliver,
And for do that I need physically another button correct ? 
so it's very complete your menu ! Many Congratulations ... !!! So I promise to you that when I'll finish the project I'll send to you a gift please send to me in private if you want without you I was completely lost ...
So the final things that I want do for the moment is that ... in attachment you can see a a combo menu ... I've take this simple example from a library ... one time that i will press ok I will store the value devices and the "Is" name (only the index) inside my array ... for example like this:
array[0][13] = idx;
array[0][0] = &u8num;
Then I would like retrieve this value inside another menù:
I would like that for example when I'm inside the menu device when I click on "Dev: 01" Will appear kitchen ...
In this way I can say what Im managing ...
Could be possible for you ? make sense ?
Thanks again
