Thank you so much for using our theme and using support forum for the query as well.
We have Slider Widget to make the slider on the sidebar.(Hope you are using it). If you need to remove margin around the sidebar slider, you need to edit with CSS, because while developing theme, we added the margin to make the design good. If you don’t like that, you need to remove it. Please provide the link of your site with that slider on the sidebar, we will check and provide the custom css for it.
We think the design will look weird. And it’s impossible to add two slider on sidebar one after another now, but it may be with CSS. Add the two slider on sidebars and let us know the link, we will check and inform you is that possible or not.
Hope, you understand what we mean. Confused !! Just reply here. We will do our best to solve your problem.
