Hello guyz,

am testing the following javascript (its a kind of JS-menu) and works all right, but i want to get something more..

If i click ones, (par example) on

Quote:

"menu item 1"

,
i will get :

Quote:

menu sub item
menu sub item
menu sub item
menu sub item
menu sub item
menu sub item

But,, if i try to click on

Quote:

"menu item 1"

again,
then nothing will happend

..and the :

Quote:

menu sub item
menu sub item
menu sub item
menu sub item
menu sub item
menu sub item

..will not appear

..this is what i want to solve, so when i click on "menu item 1" , "menu item 2" , " menu item 3 " again after ones to work like before the fist time .

Please help me to do this,

the quickest way: verify the state (the visibility) of each div, and if the div is hidden, make it visible...

but this is happening already in the script no ?

hm can you give an example based on the code above plz ?

I'll think about it...
