thx for all, i'll use a plugin joomla to copy the created date in a custom field but in the format i want and automatically fill it each time i create/update a content: i'll display it in the list instead of the real date which will be here too, but hidden in css.
last question
I really need to search by MULTIPLE tag : not by radio, but checkbox.
Do you will work on that on a next version ? can i buy this improvement if not? what is the price ?
thx for all !
