1) Script Title: Animated Collapsible

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex17/animatedcollapse.htm

3) Describe problem: I would like to show the script initially expanded by default.


When I change visibility values it works but the link which controls the script (calls to "slideit" function) stops working. Can someone please help me with this?

Thank you in advance.

How are you initially hiding the DIVs? For example, are you using the parameter option when initializing the script:


animatedcollapse.addDiv('rabbit', 'fade=0,speed=400,group=pets,hide=1')

I solved it. After reading your comment I took a look at my main file where there are the div parametres.

//Syntax: var uniquevar=new animatedcollapse("DIV_id", animatetime_milisec, enablepersist(true/fase), [initialstate] )

Following the help text I changed this:


var collapse2=new animatedcollapse("footer", 800, true)

to this:


var collapse2=new animatedcollapse("footer", 800, false, "block")

Then the script is initially expanded. Thanks for your support.
