Read_only - how to set dynamically

Hello @Kal_Lam, @martijnr,
Any news on this. Still seems not working in Enketo (incl. Online Validator).

github seems not much interested? But it is marked as a priority in Enketo Roadmap

If would like to suggest to add at least a hint in the http://xlsform.org/en/ref-table/ as it doesn’t explain the problem with Enketo, but says: “… or a statement that evaluates as true or false”. The same for dynamic default, please.

There are several requirements and related posts in this forum, e.g. Dynamic default and read_only

A typical usage would be using a choice_filter and set dynamically the valid forced option to read_only. For ex. Person is father, now in following sex question restrict to “male” as choice and set it (calculation) and show it as read_only. But if person is something else, allow free choice.
