luceos AntoCfpbna Thanks for your question, could you please clarify what you mean. Also, because I cannot send you a direct message and the suspend option is currently out of order, I'd like to suggest to you to stop posting off-topic comments in (old) threads. As I have no way to suspend you temporarily or permantly, the other solution would be to delete your account altogether. If you want to test the features of Flarum, please use the Sandbox tag.
AntoCfpbna sorry for my test, i search just to add img in my post but i found answer nowhere... and for my first question i would like a little icon like category but in sub category, it's possible??
Franz AntoCfpbna But where do you see images for categories? Or do you mean the small colored squares?
Red Maybe it will be enough for now? Add code below to Custom Styles (Admin->Appearance->Edit Custom CSS) .sideNav .Dropdown--select .Dropdown-menu > li > a.child:before { content: '\f105'; margin-right: 5px; font: normal normal normal 14px/1 FontAwesome; }
Red Like this:  or just install Imgur Upload extension. To embed videos and third party content check the MediaEmbed extension.
