ListViem is lagging while the number of items scales up

[gusye1234]

Hi, I'm trying to implement a TXT reader based on textual.
But I can experience significant display lagging while I have a ListViem to mount (but the size is only 955).

Is it normal? Or by design, ListViem is not supposed to be used in this case

ListItem is really designed for lists on the smaller side, each item in the list is a widget in its own right (and in turn can contain multiple widgets). Adding lots of widgets will slow things down a wee bit.

Depending on what it is you're wanting to do, you'll probably find that OptionList is better suited to your needs here; it's just a single widget and can contain lots of content without any noticeable impact.
