Thymeleaf: how to use conditionals to add/remove dynamically a CSS class
Tags: html,css,thymeleaf
Problem :
By using Thymeleaf as template engine, is it possible to add/remove dynamically a CSS class to/from a simple div with the th:if clause?
Normally, I could use the conditional clause as follows:
<a href="lorem-ipsum.html" th:if="${condition}">Lorem Ipsum</a>
We will be creating a link to the lorem ipsum page, but only if condition clause is true.
I'm looking for something different: I'd a block always visible, but with changeable classes according to the situation.
Solution :
There is also th:classappend.
<a href="" class="baseclass" th:classappend="${isAdmin} ? adminclass : userclass"></a>
If isAdmin is true, then this will result in:
<a href="" class="baseclass adminclass"></a>
