First, add ValueChangedFcn callback from app.CheckBox.
Then, define CheckBoxValueChanged function as the follows.s
% Value changed function: CheckBox
function CheckBoxValueChanged(app, event)
value = app.CheckBox.Value;
if value == true
% If checkbox is checked, make dropdown disable
app.DropDown.Enable = false;
else
% If checkbox is unchcked, make dropdown enable
app.DropDown.Enable = true;
end
end
Here is a screenshot.

If I want to save my output file from the APP designer which function can I use? I didn't find nothing correlated to my question on the web. Thank you

You can use save (as .mat file), writetable (as .csv or .txt, .xlsx) and so on.
