Django - "> 符号出现在表单字段 manytomany 和外键的外面

如何解决Django - "> 符号出现在表单字段 manytomany 和外键的外面

我的 django 项目中呈现的 html 模板有问题，以下符号 "> 出现在我的表单字段的外部，这些字段从许多关系 (comorbidities_ids) 中调用外键 (subjects_id)。我认为当我在 html 中调用多条关系和外键字段的 ID 时，我犯了一些错误。有人可以帮我吗？

class Medical_Record(models.Model):
    subjects_id = models.ForeignKey(Subjects,on_delete=models.CASCADE)
    HC_number = models.CharField(max_length=20,null=False)
    diseases_id = models.ForeignKey(diseases,on_delete=models.CASCADE,null=True)
    comorbidities_ids = models.ManyToManyField(Comorbidities,null=True)
    surgery = models.TextField(null=True)
    clinical_outcomes = models.TextField(null=False)
    created = models.DateTimeField(auto_Now_add=True)
    updated = models.DateTimeField(auto_Now=True)

                                <div class="input-group mb-3">
                                    <div class="input-group-prepend">
                                         <label class="input-group-text" for="id_comorbidities_ids">Comorbidities:</label>
                                    </div>
                                    <select class="custom-select" name="comorbidities_ids" required="" id="id_comorbidities_ids" multiple="">
                                        <option value="{{ form_medical_records.comorbidities_ids }}"></option>
                                    </select>
                                </div>
