I have two related questions:
1) Do particles have a limit(hard or soft) regarding how many items it can handle? I understand most particles allow user to input a number on how many items they prepare or fetch, this can easily be bypassed by editing twig and yaml files if I want the particle to display lots of content(i.e., 500 items). I notice that for Joomla articles when I set this number to be more than 99, there will be a red underline, does this mean the particle had better not have more than 99 items? If it does have more hundreds of items, will it create any problem?

2) If it is practical to have hundreds of items for a particle, then what about pagination? In Joomla Article Particle, I see there is a "pagination" setting, but I don't quite understand what it does. Also according to gantry's documentation, http://docs.gantry.org/gantry5/advanced/content-in-particles, the pagination seems to be possible. If it is, is there any particle around that actually uses pagination so I can learn?

Thanks!
