Dependent dropdown availability in a New UX Form




I have created a Form in the New UX which contains 2 list formatted line items - L1 and L2.


The lists have a Parent-Child relation, so I have set the selection in Line Item 'L2' to be dependent upon the selection in Line Item 'L1'.


This works well when we are making the selections in the module grid, but when we select the result for L1, the dependent dropdown doesn't work for L2. Thus, L2 is displaying the entire list.


Is the dependent dropdown not yet available in case of a Form? If not, is there any clarity on when it might be released?
