Nicepage Megamenu missing "active background color" for Headings

Dear developers,

just discovered a missing feature when working with the mega menu in Nicepage.

If you are editing items

, you are able to define background colors for each condition (active, color, hover).

If you are editing heading items

you are not able to define the background color for the active condition, just hover and color.

If you can't define it, it's always grey, if active as seen on https://els.gigaboom.de/schule/berufswegeplanung (Menu: Schule > Berufswegsplanung).

Can this please added/fixed for the next release?
