Yes...
So by default only 40 items are loaded... We need to increase it to 150. So that all items are loaded at once and no need of on scroll pagination.
if we change the limit property at below path it works but as we should not be changing anything in /libs folder we wanted make it project specific.
We tried overlaying it to /apps/ folder which works but again it is also applicable to all tentants. So requesting help to make it project specific.
Path : /libs/cq/gui/content/coral/common/form/tagfield/picker/views/column limit (property) = 40
Thanks for replying.
