module class suffix not working with sparky menu

I have a drop down menu created in the spraky pro template, and I would like to add a module suffix to add a background color, but for some reason, it does not seem to work no matter what I try.

what is the correct way of doing this with sparky pro?

Also the menu is a dropdown menu with only 4 items but i want the menu to stretch across the width of the page whilst keeping the items aligned to the left. How would I adress this on the sparky template as the menu setting do not allow me to set a wifth for the menu.

Many Thanks

In sarky you can set background form template options in menu configuration

i cant see how to do this where do i find the menu configuration?

In joomla admin go to Extensions->Template Manager, then click on sparky_framework. Sparky options will show, on tab will be named "menu config", enter that tab to configure menus.

My menu settings for the sparky template pro has no options for the drop down menu to set the width of the whole menu, it has an option for the button width

I had a problem yesterday with the template where all of a sudden it dropped the layout, thus having a blank screen. But I fixed that now.

Menu will be wide as sum of items width in it?
