ok i figured it out. Documentation is a bit vague but have worked-out where to do it all.
Creating an accordion slider is done through theme options under appearance. You first create a new slide by giving it a name and then refresh your theme options page, under slider settings there will be two items, one of them is the name of the slider you created. Select that item and on the right panel you can choose the type of slider it is meant to be and add images and text to each slide of the slider.
Thanks a lot adomita for sharing and pointing this out, we will make sure to make the user experience better for creating and handling sliders.
Please let us know if you feel that anything else needs tweaking, your feedback is much appreciated.
