Description
This PR improves the responsiveness of the filter modal on mobile browsers by only partially displaying mons in chunks of 100. The user can load the next chunks by pressing the new "Load More..." button.
Furthermore, I have changed the former approach of using the
IntersectionObserver
to plain lazy loading of images.Hint: Unfortunately, this partially breaks the search functionality as only displayed items are searchable.
Motivation and Context
Currently, the huge amount of >800 mons and the corresponding amount of html nodes freezes mobile browsers when the filter dialog is opened.
How Has This Been Tested?
Own instance on desktop (OSX) and mobile (Android) Chrome.
