Dropdown selector with a long list is very slow #103
This might be a plotly issue rather than a Dash issue, I'm not sure.
We've built some dropdown selectors that have very long lists of options (several thousand), and trying to use them is very slow. I couldn't figure out where the options are stored, but I did confirm that it's not going back to the server at least (because I can stop the server and still select a new item).
If there's a way to make the widget more responsive at the expense of memory that would be well worth it for us.
Ah yeah, different story with 23,000 items. That is slow! It looks like we could maybe swap out the dropdown with https://github.com/bvaughn/react-virtualized-select/ to make it faster....
