App Designer Drop-Down ItemsData

I have a drop down list with 5 items and I want to associate each item to have a cell of 2 values (a density and a bulk modulus). How can I write this code such that MATLAB does not treat them as characters. Additionally, how can I then access these two numbers separatley in a callback function?

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.

Refer to this for more information.
