Issue
please, I want ask something about parametrized fragments in Thymeleaf. I have homepage.html , it is thymeleaf template to which I am sending Model model by Controller (Java, Spring). this model has this value: "AllComments: listOfComments". listOfComments is varirable of type List with Comment objects in.
I want to use this "AllComments" variable in fragment "comment". (to print table). How can I send this variable from homepage.html through layout.html to fragment in fragments.html ? Thank you for answer.

Solution
Just pass the variable to where you use the fragment:
<div th:replace="fragments/fragments :: comments(${AllComments})" />
