in thymeleaf, how can write th:each to combine rows and columns?

问题:

I want to write 4 columns in a row like this

    
Something
    
Something
    
Something
    
Something
 
 
    
Something
    
Something
    
Something
    
Something
 
 

data sizes are dynamic, so it can be 4, 8 or more. this is archived in other template engine

{{#each list}}   {{#if @index % 4 == 0}}     
   {{/if}}   
{{this.name}}
   {{#if @index % 4 == 0}}     
   {{/if}} {{/each}} 

but how can I archive this in thymeleaf? I can't find the way because th:each is in tag(

or

) as attribute.

MODEL CODE

    List data = new ArrayList();     data.add("1");     data.add("2");     data.add("3");     data.add("4");     data.add("5");     data.add("6");     data.add("7");     data.add("8");      model.addAttribute("datas", data); 

THYMELEAF VIEW CODE

     data 
 

RESULT

     1234 
 
     5678 
 

I used an array to solve this problem . I think you will find a better way .

回答2:

I just created an account here to correct the accepted answer. The accepted answer works great so long as the "datas" being passed in is an array of consecutive integers. However, to make it work with any kind of data structure, "row.current" needs to change to "row.count", as follows:

     data 
 

If you use row.current, then it uses the actual item in the list, which is great in the example shown, but not so great for any other kind of data structure. Hope this helps.

EDIT:

I have to further refine this because the accepted answer also does not work if the number of items in the list is not evenly divisible by 4. Here is a better (though probably not perfect) solution:

          data          data 
 

This may be able to be refactored to eliminate one of the spans, but I have to move on now.

回答3:

th:each can be used on any element basically. So something like this:

    
Something
 
 

回答4:

This can be done using numbers.sequence too. Set colCount to whatever number of columns you'd like:
