depending items

Depending items allow you to show items depend on values from other items.
Here an build example to use it:

First create an item on which value other items depends.
Next add a pagebreak.
Next add the items depend on the item-value before
Choose in the item creation-form the item in the list "depend item" and put the needed value into the textbox "depend value".

The structure should looks like this:

Item Q: do you have a car? A: yes/no
Pagebreak
Item Q: what color has your car?
(this item depends on item 1 with value = yes)
Item Q: why you have not a car?
(this item depends on item 1 with value = no)
... other items
