Hi Alex,
I understood you want to map every item of drop down to a cell of 2 values (Density and BulkModulus)
you can achieve this by following code
app.DropDown.Items={'Item-1','Item-2','Item-3','Item-4','Item-5'};
app.DropDown.ItemsData={{1,2},{3,4},{5,6},{7,8},{9,10}};
Accessing the current value of dropdown can be done as follows
value = app.DropDown.Value;
density = value{1};
bulkModulus = value{2};
Accessing the whole data for every item in the dropdown can be done as follows
dataArray = app.DropDown.ItemsData % cell array that contains each value associated with corresponding item in drop down
I have attached the app that demonstrates the same.
