Hi,
sorry this is not a feature. Easy Profile is mainly a profiler extension, to do this we recommend to use a component that manage "history jobs". For example to manage images gallery you can use a gallery component.

Hi,
sorry I don't know, we only talk about Easy Profile.

Try to search in Joomla Extension Directory, if you do not find this then you can always use some CCK component.

No, triggers are for others purpose (operation between fields, sync with other components, post operations).

Hi,
I'm sorry but as I already said Easy Profile does not do this.

Hi,
sorry but we does not support custom code.

I want write 1 code jquery in file tab.js to when click a link

This is not possible with a simple way, anyway Easy Profile extends Joomla user management (not replace), so the best way is to write a user plugin that add a tabs and store informations (documentation about this is not related to Easy Profile, but it is related to Joomla).

Keep in mind that something like this can take many hours of works (if you are expert Joomla developer).

An example of user plugin is installed in all Joomla installation and disabled by default, to enable and check how it works you can go to Extensions->Plugins and enable plugin called "User - Profile". This plugin add some new field to Joomla Profile (so also in Easy Profile)
