liferay - How can I add extra properties to document metadata field types in Liferay 6.1?

Question

I'm new to Liferay and I have the following situation:

I would like to add extra properties to document metadata field types in Liferay 6.1.20.

For example, I would like to add property 'readonly' to select boxes (see image), as it is a user requirement to show some controls disabled.

Should I use the Expando functionality, a jsp override hook or another approach?

Answer 1

我认为 Expando 功能、jsp 覆盖挂钩是一个很好的方法。但是使用 Expando 你不能将它创建为必填字段。
