Do you have adsclarity template ?

If you don't have it, it's just a mod_adsmanager_ads or mod_paidsystem_feat without effect and a module override to display ads (3 by column)
there is no option to do that without html override currently

Hello,

In the code of AdsClarity, 'templates/adsclarity/html/com_adsmanager/mod_paidsystem_feat/grid.php' you can see that line:
That mean, on xs device (mobiel phone), we will use col-xs-12, that mean the whole line (One ad per line).
On sm device (tablet with a small screen), we will use col-sm-6, that mean 2 ads per line.
On md end lg (Large tablette and desktop), we will use col-md-4 or col-lg-4, that mean 3 ads per line.

The method used seperate the line in 12 parts, the 4 mean that 3 elements will be displayed on one line (4x3 = 12).

If you wish to display 6 ads on one line, you must use that class 'col-md-2' and 'col-lg-2' (6x2 = 12).

Please, be aware that the design of the grid was not calculated for that size so it is possible that you will see some error in the grid (larger image or text not aligned correctly).

Best regards.

Yes, you need to change the classes to have that :
