select 类型的输入是否可以通过不扫描列表的选项 go 完成？

Question

an option can be just an object instead of a list of objects?

in the documentation each sweeps a list but I would like to retrieve a single object

<select th:field="*{type}">
  <option th:each="type : ${allTypes}" 
          th:value="${type}" 
          th:text="#{${'seedstarter.type.' + type}}">Wireframe</option>
</select>

is possible do somethint like

  <option th:each="${Types}"

Answer 1

The Standard Dialect in thymeleaf offers Using th:each . Its the Iteration basics.

“for each element in the result of evaluating ${allTypes}, repeat this fragment of template setting that element into a variable called type”.

Dropdown Selector usually is for a list of options to be displayed.

You simply cant do th:each="${Types}" , as you need to declare a variable to access the iterated variable
