In Spring Boot Thymeleaf , how to pass list of object to th:value ??? I would like to create tag input

  1. Here is my form html

           <form action="@{/orgCategoryTag/create}"  method="POST">
              <div class="form-group">
                <label for="form-tags-1" class="text-dark font-bold">Add new tags</label>
                <input id="form-tags-1" name="tags-1" type="text" th:value="${tags}">
              </div>
              <a
                  type="button"
                  class="btn btn-success" href="#"

            OrgCategory orgCategory = new OrgCategory();
            List<OrgCategoryTagModel> orgCategoryTags = orgCategoryTagRestController.getAllByCategoryId(testId);
            model.addAttribute("category", orgCategory);
            model.addAttribute("tags", orgCategoryTags);
            model.addAttribute("add", true);

For displaying a list of options (tags in your context), please use a combo-box, they are better suited to display a list of options.

<select>
      <option
           th:each="tag: ${tags}"
           th:text="${tag.name}"
           th:value="${tag.id}"
      />
</select>

<select> is the tag for creating a combobox and <option> are the different options available in the combobox. I have used a for each loop to create different options for the combobox where tag represents your object OrgCategoryTagModel.

I do not know your object OrgCategoryTagModel, but I am assuming you want to display the name of the tag (tag.name) and use the id of OrgCategoryTagModel (tag.id) as the value to be saved when making a selection.
