Date filter

[aje]

How can i have an list filter with a dropdown with 1 month, 3 month, 6 month ?

Then you must create a calc-element first to change your date into (int) values:

$mydate = '{TABLENAMExxxxx___DateTime}';
return $mydate = date("m",strtotime($mydate));

Then you can make the filter in list settings.
