I know that some themes the sliders work by taking post and showing them from the categorys. Then the sliders that show popular stories display the ones that have been clicked the most. Is there anyway to display 4 other (small) main stories along with the large one on the slider ?
Actually Popular Stories Section doesn’t shows the popular posts. Its is just the Title for the Section. You have set to the desired category from customizer to be shown on that section.
and Yes Top Stories and Editor pick section also shows the post that is assigned to the respective category but if the option to show by category is not set on customizer then the latest post will be shown on those section.
