ListBoxValue = get(handles.listbox1,'value');
f=MyListOfFiles{ListBoxValue};
g=find(strcmp(List,f));

List(i,:)=MyListOfFiles(ListBoxValue);
set(handles.listbox2,'String',List);
i=i+1;

msgbox('Switch to the next tab for operator setting')

Hi,
There is an option to select multiple items in a list box. By default, it is not selected.
Here’s the option for Multiselect in Interactivity under Inspector.
To test, consider a sample case where to display all the items selected in a UI table. However, the order of items in UI table depends on the order of selection from list box.
Hope this helps.
