Examples for instance invokations of class that inherit 'item'.
1. An email item. It has a unique validation method that checks the email syntax and the existance of the domain. This item's instance uses a 'item_second_title' variable which causes it's title to be displayed following the input field. The parameters that are being passed to the __init__ method are the item's key, value, name of a help file (if it is given, an anchored help icon is displayed) and the lengths of the field and maximal length of input. 2. An option list item. The item has an associated 'option_list' to be displayed. The parameter '3' given following the help file determines the option to be selected by default. The 'line_break' data field determines if the item can be displayed on the same line with other items or not. 3. A special case of an item that supports a concept of data hiding. This item is initially hidden. It becomes non-valid (and thus visual) only if the submitter provided information that is associated with the item's field. For example here, only if the submitter submits the sequence of a virus, this checkbox will be presented, requesting further details about the nature of the virus. 4. An obligatory numeric item with minimum and maximum values. The item is non-valid as long as it's value is empty or out of the range given. This overlap in validations may seem as redundant, but since the minimum/maximum fields may be ommited (any range is allowed), this is not the case.
