Dont know if i got your question. but that arrow in slider shows when u choose slider to show( in theme options) and :
“Click on Appearance -> Themes options -> Click on Slider Settings Tab
You’ll see Select a Category option, select category as Slider.
All the post under this category will appear as a slider
You can configure all Slider Settings from this menu
Click on Save Option”.
dont know if this is of any help.
