Thymeleaf - custom attribute

Question

I need to set custom attribute (data-validation-matches-message) value from messages resources.

<input data-validation-matches-message="Text from messages resources" /> 

I can receive and print messages resources value as:

<p th:text="#{user.notfound}"></p> 

But how I can set this value for a custom attribute (data-validation-matches-message)?

UPD (I use this)

<input th:attr="data-validation-matches-message=#{user.notfound}"/> 

Answer 1

Since Thymeleaf 2.1 you can do this:

<a data-th-attr="data-groupid=${somevalue}, data-groupname=${someothervalue}">...</a>
