[BangPypers] Fwd: Regarding Forms : "ModelMultipleChoiceField"

[Nikhileshkumar Ikhar]

With 5000 choices, it is not a good design from performance n usability
point of view.

How many times these choices will be accessed? If frequently you have to
add them in cache n use ajax calls.
If not so frequently then you can go ahead with current design.

But i would suggest to use ajax calls to narrow down the list of choices.
You can built a trie structure or something similar at backbend.
At front end user will type some characters and you will fire ajax calls to
get relevant results and show it to users.
