I have some columns on the same page that uses react-list. In each one I have 200 items. Seven are visible in the portview, and 13 are rendered, I load more on scroll.
When I open a column item in fullwidth, all the other columns are hidden (display: 'none';). Here my problem started with react-list.
The viewport of those columns was 0 (they are hidden, remember?). and some how react-list started to render all the 200 items for every column.
The
end
was getting bigger and bigger from the threshold (let end = scroll + this.getViewportSize() + threshold;
. react list was rendering more items are soon as there was more space)This caused big performance issues in my app. What I've tried to achieve here is to stop react list on rendering items when it is hidden (display: 'none';).
