Thymeleaf + spring dynamic replace

Question

Is it possible to create a dynamic replace in Thymeleaf?

I have the following controller:

@Controller
public class LoginController {

    @RequestMapping         


        

Answer 1

I believe the appropriate method to manage this behavior in thymeleaf is to use layout:fragment tags. Please correct me if I'm wrong. Here is a simple example of my layout page, and the login page which is 'dynamically' loaded:

layout.html

Then, when login gets loaded, it replaces the th:fragment div with the associated div in the html view which matches the string returned by the controller method, in this case login.html:

    



    

        
 User Name :  
        
 Password:  
        

    

Now, if you want to load another fragment conditionally, the approach I take is to add replace tags with th:if cases. Here's an example of a Form that displays different questions based on an attribute of the current user:

Then the associated div gets loaded from the file custom-questions.html:

  //stuff



  //stuff
