在foreign_table_where中重用Flexformvalue

Question

选择一个组后，我想要显示与这些组匹配的所有类别。这可能吗？

<settings.flexform.categorygroups>
                    <TCEforms>
                        <label>Category</label>
                        <displayCond>FIELD:switchableControllerActions:=:Job->list</displayCond>
                        <config>
                            <type>select</type>
                            <foreign_table>tx_ext_domain_model_jobcategorygroup</foreign_table>
                            <minitems>1</minitems>
                            <maxitems>99</maxitems>
                            <size>4</size>
                        </config>
                    </TCEforms>
                </settings.flexform.categorygroups>


<settings.flexform.categories>
                    <TCEforms>
                        <label>Category</label>
                        <displayCond>FIELD:settings.flexform.categorygroups:REQ:true</displayCond>
                        <config>
                            <type>select</type>
                            <foreign_table>tx_ext_domain_model_jobcategory</foreign_table>
                            <foreign_table_where>AND tx_ext_domain_model_jobcategory.job_category_group IN (###jobcategory###)</foreign_table_where>
                            <minitems>1</minitems>
                            <maxitems>99</maxitems>
                            <size>4</size>
                        </config>
                    </TCEforms>
                </settings.flexform.categories>

如何填写'IN'？

在TCA中，有一些标记可用于此类内容。不确定它是否也适用于Flexforms。 https://docs.typo3.org/typo3cms/TCAReference/Reference/Columns/Select/Index.html#foreign-table-where
