Add Data with Header to a ListBox in a UserForm based on a ComboBox selection

[KolGuyXcel]

The userform that I'm using has a combobox and a "following" listbox. The list for the combobox is a unique list getting generated from column A of the worksheet which has repetitive values. The first row in the worksheet is the header that I want to use in the listbox. Also I want to add the columns (excluding the first one which is getting selected in the combobox) of only the relevant rows where the value in the first column matches the value selected in the combobox.
Please note the header from row 1 (Column B through the rightmost column) would also be helpful in the listbox.
