This part is quite new in TZ Portfolio Plus. Different from TZ Portfolio, in TZ Portfolio Plus, we changed things such as comments, socials, media types into addons.
They will be installed/uninstalled into TZ Portfolio Plus without affecting TZ Portfolio Plus's basic core system.
In the first version of TZ Portfolio Plus, we have only developed some addons including Content addons: comments and socials and Media types: video, audio, link, quote and image gallery and a lot more in the future.
II. ONLINE ONE-CLICK INSTALLATION:
It's recommended that add-ons should be installed directly from your Joomla back-end.
Please go to Admin > TZ Portfolio Plus > Add-ons > Click install button > Navigate the add-on you need > click Install Now button
