It only works once in expandable recyclerview using epoxy
I'm making an expandable Nested RecyclerView using Epoxy.
made it to some extent, but the problem is that when I press the expand button, it expands, but it doesn't come back.
I'm not sure where I went wrong.
What's wrong?
ParentItem
data class ParentItem(
val workout: String="sex",
val list: List, // Child Item
val isExpandable : Boolean = false
)

ParentEpoxyController
class ParentEpoxyController : EpoxyController() {
private lateinit var data : List

override fun...
