let's make dynamic select list in shared components, , need insert dynamic select list in html code. there method insert in code?

let have following lov name my_lov:

select 'red' d, 1 r dual  union select 'green', 2   dual  union select 'blue',  3   dual

so bit difficult write html manually, can generate html code in pl/sql block. need package apex_item. has number of functions, generate html code of standard elements. select lists can use 1 of following functions:

• select_list
• select_list_from_lov
• select_list_from_lov_xl

in case, need select_list_from_lov or select_list_from_lov_xl. need change region type pl/sql , write following source code region:

begin   htp.p(apex_item.select_list_from_lov(p_idx => 1, p_lov => 'my_lov')); end; 

also need know: package apex_application has number of variables names g_fxx, xx - number between 1 , 50. these variables used data exchange between server , browser. in example of pl/sql code 1 - number of such variable (as f01 in example of html code above). need choose number, not busy on page.
