Deactivate Symbols in MainTimeline via Actions in symbols An_CC_2015

Hi guys,

I am creating a web-tutorial which will be complex in Edge Animate CC 2015.

i have a navigationbar on the left which is on top.

then i have several categories.

every category starts in the main timeline at 0:00:000

and for easy adding new categories, i made every category to be a symbol.

so i have

-Navigationbar

-Category 1

-Category 2

-Category 3

-Category 4

...

as layers on my stage.

But:

Every category uses full size of stage,

so if I am in category 2 i can't press any button becase category 1 is still active...

how to deactivate the categories if i play the symbols?

i tried to create a new order of the layers via z-index.

so after starting another category the actual category is on top...

didn't worked...

Used this code:

(this is in the symbol after playing about 100ms)

sym.$("_Erster_Start").css({"Z-index":-520});

sym.$("_Apps_Sperren").css({"Z-index":510});

sym.$("_Nachtsperre").css({"Z-index":-530});

sym.$("_Ferienmodus").css({"Z-index":-540});

sym.$("_Sicheres_Surfen").css({"Z-index":-550});

sym.$("_System_Berechtigungen").css({"Z-index":-560});

sym.$("_Nutzungsstatistiken").css({"Z-index":-570});

sym.$("_Schutz_Verlaengern").css({"Z-index":-580});

sym.$("_Freunde_Werben").css({"Z-index":-590});

sym.$("_Account_Verwalten").css({"Z-index":-600});

sym.$("_PW_Vergessen").css({"Z-index":-610});

sym.$("_PYK_Neu_Einstellen").css({"Z-index":-620});

sym.$("_Problem_Melden").css({"Z-index":-630});

didn't work...

then i thought to disable the other symbols using display:none;

sym.$("_Erster_Start").css({display:none});

sym.$("_Apps_Sperren").css({"Z-index":510});

sym.$("_Nachtsperre").css({display:none});

sym.$("_Ferienmodus").css({display:none});

sym.$("_Sicheres_Surfen").css({display:none});

sym.$("_System_Berechtigungen").css({display:none});

sym.$("_Nutzungsstatistiken").css({display:none});

sym.$("_Schutz_Verlaengern").css({display:none});

sym.$("_Freunde_Werben").css({display:none});

sym.$("_Account_Verwalten").css({display:none});

sym.$("_PW_Vergessen").css({display:none});

sym.$("_PYK_Neu_Einstellen").css({display:none});

sym.$("_Problem_Melden").css({display:none});

didn't work as well...

_Erster_Start is still active on top  and i can't use my buttons to move to the next step in _Apps_Sperren.
