Thymeleaf - Include content of fragment
try the below
<div th:fragment="assets" th:remove="tag">
<script src="myscript"></script>
<script src="myscript2"></script>
</div>
You can use th:block to include only content of a block.
Define your fragment like -
<th:block th:fragment="assets">
<script src="myscript"></script>
<script src="myscript2"></script>
</th:block>
And include like this -
<th:block th:include="fragments/assets :: assets"></th:block>
Hope this will help you :)
