We prefer the wrapped solution or a url Link solution that we give us a lot of choices in Elxis than an unsecured Joomla Module

Don't use Joomla's extensions in Elxis! The security risk is high. Although the 2 CMSs look similar they have a completely different core. More over Elxis and Joomla have a completely different access system. See bellow why. Also is a very bad idea to be able someone to write php code from within administration! Don't use such tools in your sites.

See why you should not use anything from joomla in Elxis.
Joomla:
Items allowed to be access by visitors belong to user group 0.
Elxis:
Items allowed to be access by visitors belong to user group 29.

Joomla:
Items allowed to be access by registered users belong to user group 1.
Elxis:
Items allowed to be access by registered users belong to user group 18.

Joomla:
It is safe to rely on group names and IDs as they are always the same.
Elxis:
In Elxis user groups can be edited, added or even deleted so it is not safe to rely or their names or their ids!

Joomla's access check:
Item access <= $my->gid   then allow

Elxis's access check:
Item access IN ($my->allowed)  then allow

Joomla's access checks in Elxis are always true (even the visitors belong to a user group with id 29), so visitors may gain access to areas only for registered users! Elxis access system is much more advanced and work completely differently.
