Group of inputs in DynamicForm?

Question

Play Framework

POST data from fields is transmitted from the client

<input name="inpt[]" value="val1">
<input name="inpt[]" value="val2">

But if you try to take this array from DynamicForm under the name inpt, it returns null , since these fields are not named under the same group, but as independent fields of the format inpt[0 , inpt[1 . The most interesting thing is that they can only be obtained by adding a square bracket and an index, and without closing this bracket (looks like a bug).
Then it turns out that you need to manually sort through these fields, or are there methods built into DynamicForm to get such groups?
