Load data from table into apex_util.select_list multiple - oracle-apex

Question

I have a Classic Report with a schedule for each day. There are no, one or multiple entries per day. It looks like this:
select
week_no,
apex_item.DISPLAY_AND_SAVE(p_idx => 8, p_value => plan_id) as ID,
apex_item.select_list(p_idx => 1, p_list_values => 'S1;1,S2;2,S3;3', p_attributes => 'size="3" multiple="multiple"', p_show_null => 'NO', p_show_extra => 'NO', p_item_id => plan_id || '_1', p_value => monday) as monday,
apex_item.select_list(p_idx => 2, p_list_values => 'S1;1,S2;2,S3;3', p_attributes => 'size="3" multiple="multiple"', p_show_null => 'NO', p_show_extra => 'NO', p_item_id => plan_id || '_2', p_value => tuesday) as tuesday,
apex_item.select_list(p_idx => 3, p_list_values => 'S1;1,S2;2,S3;3', p_attributes => 'size="3" multiple="multiple"', p_show_null => 'NO', p_show_extra => 'NO', p_item_id => plan_id || '_3', p_value => wednesday) as wednesday
from plan;
I can select multiple values and can save them to my table. It gets save like this "1,2". But I can't load the data rows with multiple selected values.
I can select multiple options with jQuery like this
$('#1000_1').val(["1","2"]);
but I don't know how to select the stored values from table with PL/SQL and then set the options selected with javascript.
I tried to load the data in an apex_item.text (id="1000_11" for monday etc.) and transfer the values in "After Refresh" DA to select list like that:
var sel_opt = $('#1000_11').val();
if (sel_opt == "1,2")
{
$('#1000_1').val(["1","2"]);
}
else if (sel_opt == "1,3")
{
$('#1000_1').val(["1","3"]);
}
else if (sel_opt == "2,3")
{
$('#1000_1').val(["2","3"]);
}
else if (sel_opt == "1,2,3")
{
$('#1000_1').val(["1","2","3"]);
}
It works, but maybe there's a smarter solution?

I would create SELECT LIST page items for each selection menu and set their multi selection option to Yes.
then I'm guessing I'd need something like this somewhere at my page-process section
declare
array apex_application_global.vc_arr2;
begin
array := apex_util.string_to_table (:P30_SELECT_LIST_1);
apex_collection.create_or_truncate_collection ('P30_SELECT_LIST_1');
apex_collection.add_members ('P30_SELECT_LIST_1', array);
end;
to store more than one menu item at once.
then I'd add something like that to my query
and ITEM_1 in (
select c001
from apex_collections
where collection_name = 'P30_SELECT_LIST_1'
)
I probably didn't understand your question, but according to part that I get, it's straightforward sql query. no need for js.
