If you go in "Les courses" > "Résultats", you will have a big sub-level with 10 items.
On a 17'' screen or higher, you will not have problem to click on the last item "2001", but if you use a laptop with a 12'' or 14'' screen and the touchpad, it's become difficult to reach this item.
Is-it possible to make 2 colums of five items?
In general manner, is-it possible to modify the behavior of the menu, for example if 8 sublevels > make 2 colums of 4?
You can easily do this with the RokNavMenu extension but it is a club extension and thus would require a subscription. I believe it is worth it for the many club extensions you get access to.
Are you sure that RokNavMenu extension allow me to do what i want. Because I have installed this extension and i don't find the way to have two columns in the sublevel.
quasar is a free template and does not support the roknavmenu at this point.
roknavmenu would be needed to have 2 columns in the dropdown.
i am not sure if there are any plans to update quasar with this functionality, but the core gantry template rt_gantry_j15 has been updated with roknavmenu support.
you could download that template and with some knowledge in coding you could try to port this into quasar.
