Django根据另一个字段的值使下拉选项不同

Question

关于帐户注册的下拉选项，我有一个快速的问题。我有2个字段，分别是Acccount类型和Business类型。帐户类型是一个带2个选项的下拉列表，分别为“ Vendor”和“ Venue”。业务类型是具有许多选项的下拉列表。如果在“帐户类型”下拉列表中选择了“ Vendor”，我仅希望下拉列表选项可访问。我可以使用if else语句在模板中处理吗？我有一个小片段可供参考。

 <div class="form-group">
                            <label for="account_type">Account Type<span>*</span></label>
                            <div class="select-panel required">
                                <select required class="selectpicker" name="account" id="multi-category"
                                    title="Select a category">
                                    <option>Vendor</option>
                                    <option>Venue</option>
                                </select>
                                <span id="span_account_type" class="error-msg"></span>
                            </div>
                            <!--<input type="text" name="business_type" class="form-control required" id="business_type" placeholder="Business Type" value="{{business}}" maxlength="20">-->
                            {% if account_error %}
                            <span class="error-msg">
                                    {{account_error}}
                                </span>
                            {% endif %}
                        </div>
                        <div class="form-group">
                            <label for="business_type">Business Type<span>*</span></label>
                            <div class="select-panel required">
                                <select class="selectpicker" name="business" multiple="multiple" id="multi-category"
                                    title="Select a category">
                                    {% for business in business_types %}
                                        <option value="{{ business.id }}">{{ business.name }}</option>
                                    {% endfor %}
                                {% endif %}

</div>

我尝试添加类似的内容，但是没有运气。

{% if account == 'Venue' %}
       <option>-----</option>
{% else %}
       {% for business in business_types %}
                  <option value="{{ business.id }}">{{ business.name }}</option>
       {% endfor %}
{% endif %}
