Hi Thanks for your purchases! This plugin works with every licensed standalone VC or bundled with theme.
Plugin uses default WP color picker and you can use only one bg color at this time and if you want to use different colors, you need to tweak / inject by css or code.
You don’t need to edit anything in frontend editor and you just need to edit all options from the backend editor.
There are two options you can edit settings:
1. By per page
2. General options
1. Per page: you can set any menu for per page
2. If you tick and save “Do you want to activate slidck side menu site wide?” setting slick side will be appears side wide.
Can you share your sample page and what you need basically? We can assist better to you quickly.
