Proposed Changes: Choice Loader Documentation

[beejayzed]

Hi All

Having recently found the choice loader quite useful, I felt the need to offer to contribute to it's documentation. Better to see if the team agrees before I do anything though.

I would like to propose something along these lines:

• Break down of how implementations of the choice loader component work, as well as how and when it's methods are called in the request/response cycle

• An example or two. Perhaps a drop down list with many options that is dynamically loaded via Ajax. (see [Form] Support "allow_add"/"allow_delete" in ChoiceType symfony#9310 (comment))

I see #5179 was closed with choice_loader documentation incomplete, and having searched other issues I haven't found anything else in progress. Would this be agreeable to go ahead with?

@beejayzed thanks for your proposal. Let's ask Jules (@HeahDude) our biggest expert in these things what's his opinion. Thanks!

Thank you for this issue.
There has not been a lot of activity here for a while. Has this been resolved?

Hello, I came across this issue and the one in the Symfony repository linked.
Indeed, the choice loader is missing some documentation, and it's very hard to find some hint to help in my use case: loading only selected choices (I have 20K+ entries in total) in a choice type from a distant source, with some JS autocomplete.

It was my first time using the choice loader, so it could be improved, but it might be a good start : symfony/symfony#9310 (comment)
Or at least it can help some people passing by :)

Should this be closed now that https://symfony.com/bundles/ux-autocomplete/current/index.html and https://ux.symfony.com/live-component/demos/form-collection-type can be used?
