THTMListBox Issue

If the THTMListBox->Coulmns > 0 HTML Tags does not work, for example P1 don't show BOLD P1
sow instead P1

This is expected. This is based on custom drawing in a Windows LISTBOX class and the Windows LISTBOX class doesn't support custom drawing when Columns > 0
If you need to a list with more columns and HTML formatted items, we recommend a TAdvListView or a TAdvStringGrid.

Is it possible to have more then one columns in TAdvListBox? As I can see Columns property is absent.

I referred to TAdvListView or a TAdvStringGrid.
