On the support page for slider, I can read this :
How to change Transition Effect, Transition Delay and Transition Length on Slider?
Make sure featured slider is enabled
Go to Customize => Theme Options => Featured Slider” from your WordPress Dashboard
To change Transition Effect, select option under “Transition Effect
To change Transition Delay, change number of second(s) under “Transition Delay” as per your need
To change Transition Length, change number of second(s) under “Transition Length” as per your need
Finally, click on “Save & Publish”
However, none of these options appears, I can only change the “transition timeout”.
Please help.
