Is there support custom topic fields by category that are operable?
One example would be to have an category whose topics require a date and then being able to sort the topics within the category by the new field?
Of course a plugin or some other customization can do it, but can you just use the built in extensibility to get there?

There is currently no facility for displaying custom topic fields.

Thanks. Would you guys consider adding such a feature? Seems like it would have wide applicability. Possible uses include:
Date/Time of event
Location
Price
Solved
Installed count (would take extra support - essentially having likes update a different field?)
Perhaps some of the code from the custom user fields support could be used.
Thanks!

I’d be interested in a feature like this. I’m planning to have a Discourse instance be the backbone of a plugin repository; each plugin would have a topic in a certain category with a field that can be set. An external frontend would then query the API for information from Discourse such as download link, version, and author.
Edit: I found this but it’s not clear how to use this. I’ve also been studying the tagging plugin but I have no idea how that works, I just want to be able to add a custom field to the json output of the topic.

对于我们的山羊奶酪市场，我会使用自定义主题字段。
我会选择“货币”格式，并在“主题视图”中添加“筛选”选项。
