Can users add images/videos (only possibly embed videos) to USERS LISTS in Cobalt ?

Hello zerevans,
you might use the Comments -> Cobalt Type-as-Comment. It allows to use another type with other fields. Please, check its related parameters in backend. The "comment" type submission can be stored in an extra section, or even in a specific category of the parent type. By default, submission form is displayed as a new page, it does not happen inline "under" your parent content. (probably could be achieved through a modal window display, so users stay visually on your initial topic title)

Apart from that, Relation fields might offer a similar functionality. Please, compare parameters and possible workflows.

Technicaly it is possible but not ideologicaly.

I understand what you want to do nd I can say the way it works now woun't work out for you. because any attached data is a new articlew and you want to extend your current article.

At the ernd you can make what you want, but that will require serioce template customisations.

I use Disqus in Comments.

In Disqus is possible to add also videos and images: https://help.disqus.com/

Maybe some little modification to Disqus but I do not know is it possible to modify Disqus ?

Sergey any attached data is a new articlew and you want to extend your current article.

Technically they are separate records… but I see no disadvantage. Any type of comment is an attachment to a parent.

IMHO, the example application is not a multi-author article. Because users have no rights to post, nor edit the initial article.

As mentioned before, the only usability difference is the submission form. It is not "inline" on the parent page… but a modal window could mimic and improve this behavior.

Good point and idea.

There is an image upload button (small). Or directly paste image-URL in comment.
Video works as well, as far as you enable the "media attachments" in settings. This is NO upload though, you just post the URL inside the comment area. disqus converts many popular video providers into a preview automatically. It does not display at once… you have to submit first to see the preview.

If you want to monetize/place ads, you might go with disqus. Not to mention the "social community" factor and sharing. It looks clean and easy. Drawbacks might be: Off-site moderation and user rights and access control. Also templating might be limited.

zerevans A. Admin creates some title and maybe first text and first image.

Like Add pictures of European cities.

B. Then different registered users can add for instance images.

User 1 add picture of London. User 2 add picture of Madrid. User 3 add picture of Berlin User 4 add Youtube video of Milano.

BTW, if you dare to take a step on the "dark side"… ;)
I have found a WordPress plugin and two accompanying themes for a similar task. So called "Open Lists".
Looks pretty nice and out-of-the-box…

• Snax – Viral Front-End Uploader
• Bunchy – Viral WordPress Theme with Open Lists
• Bimber – Viral Magazine WordPress Theme

Maybe of interest for you and a possible time saver.
Hope this helps.

Thanks so much my Friend Pepperstreet for nice answers.

Plugins seems so great.

I begun with Wordpress but my website is now Joomla based.

That first of your plugin is just what I have been looking for.

I must ask from my developer too what he thinks.
