I usually avoid repeating panels with so many items.
When there are so many items I either use:
- a DataGrid, which loads them in chunks (assuming we are dealing with a search iterator, I think 100 rows by default, or
q.page_size
) and renders them in even smaller smaller chunks (the number of items in each page) - a LinearPanel, to which I can feed items in small chunks, for example using the
AutoScroll
custom component
