menu - CSS counter on hidden submenu -

-

i'm trying make dropdown menu using nested <ul>, every <li> displaying number generated css counters.

sub-menus hidden display:none when not hovered.

my problem counters not incremented when element has display set none.

do know css property prevent this?

if replace display: none visibility: hidden, it's working i'm not sure if it's nice use menu, there traps?

you can mimick display: none (hidden) behavior setting font-size 0px , make element counted counter property.

.hidden{     font-size: 0px; }

demo

or, bit more complex version of above (mentioned hashem qolami in comments)

.hidden{     font: 0/0 a;      visibility: hidden; }

demo 2

note: visibility: hidden work leave space equivalent height of 1 line in output.

demo using visibility property
