Hi,

I'm a site administrator and was ask to disable some of modules (Banners, IFrame, FAQs,...), Idon't want to delete them.

Thanks.

That will only hide the module on the page from a visitor to the page.  I think the question is really about how to hide modules in the module drop-down list so it cannot be added to a page at all.

This is a fairly simple task.  Login as the host and go to the Host/Module Definitions screen.  Edit the module you want to hide and check the premium box that appears just above the update/cancel/delete buttons.  This will mean that the module is only available to portals that have been assigned this module (the UI for assigning modules is enabled after checking the box).  Now just click the update button, and that module will no longer be visible in the Module dropdown list.

NOTE:  If the module is already being used in a portal, it will continue to function. No new instances of the module will be able to be added using the module drop-down list.
