I have media content I want to add an option for viewers can view by year from select option. I have added Published on and then checked on exposed with year checkbox as you seen in snapshot but it showing as field instead years like: 2018, 2019 in dropdown/select option.
The 1st problem is select/option should show as years like 2018, 2019 so on.... and 2nd problem is when I clicked on apply filter it showing query as
?sort_by=publish_on&sort_order=DESC so manually I changed it to
?sort_by=2019&sort_order=DESC but still not showed posts which published on 2019.
