So I have 2 ListBox-es on my form.
On the first one, I want to have 2 items: Maths and Languages. On the second, when user clicks Maths I want to show: Algebra and Geometry, and if user clicks on Languages to display Norwegian, Swedish etc.

How to do it?

Thanks for help.

You will need an (I think) onclick event for the first listbox that clears the stringlist and uses the .add() method to add the new options to second listbox.

ListBox2.Items.Clear;
case ListBox1.ItemIndex of
0: 
begin
ListBox2.Items.Add('Algebra);
ListBox2.Items.Add('Geometry');
end;
1:
begin
ListBox2.Items.Add('Norwegian');
ListBox2.Items.Add('Swedish');
end;
end;
