in the area just before footer, there is a row with the brands logos (this low is NOT showing in visual composer interface)
I want this row to auto-scroll, to catch the attention of visitors and also I want to show the left-right arrows in this row. now, visitors can not know they can scroll to view more brands because there is no left/right hadlers
This row is added to the prefooter area and is created with HTML Block. You can find it and edit with Visual Composer in Dashboard -> HTML Blocks. There you can find all available options for the brands element.
