How do I list out all of the repetitive rows depending on the number of variables in MATLAB App Designer?

I would like to make these row repetitive based on variables that I have. If let's say user input 10 items, there will be 10 rows. Is it possible to do this? The reason why I didn't use the UI.Table is because users are able to choose different item (in dropdown menu) based on preferences.

This would be similar as picture below. Taken a snapshot from another matlab tutorial.

Hi Nurhidayah,

Yes, it is possible to add UI components to the app’s UI Figure based on a variable.

For example, if you want several UI Dropdowns equal to ‘numRows’, one below the other, you add the following code snippet to an appropriate place, such as the button-clicked callback of an Update button. Note that if you want to use variables like ‘dd1’ in another function, consider setting them as Private Properties.

for rowNum=1:numRows
    dd1(rowNum) = uidropdown(app.UIFigure, ...
        'Position', [10, 40 * (numRows - rowNum + 1), 100, 30], ...    % adjust as needed
        'Items', {'Option 1', 'Option 2', 'Option 3'}, ...
        'Tag', 'Option 1');
    
    % add the other components in appropriate positions
end

You can refer to the documentation on how to add the components programmatically here:

If the added components extend beyond the app’s UI Figure and you want to add them to a scrollable container, consider adding them to a “Panel” instead of the app's UI Figure and setting the setting the “Scrollable” property to ‘on’. More details are available in the documentation for “Panel”:

I hope this helps!
