I am not sure about the meaning of your question :
In a multicolumn Listbox, you can select several rows (to change the default single row selection mode, right click , then "Selection mode"). The control will return an array of numbers corresponding to the selected row numbers.
If you want to preselect some rows, you can use a global variable, and pass the row number(s) corresponding to the rows which should appear selected.
If you need to get the strings of the selected row, you can use a property node, as illustrated in the attached example.
And if you need more help, try to be more explicit�
