}

I have a recycler view and set data to that recycler view via adapter i need to show the recycler view when clicked and remove the recycler on other click

Your condition is out of place.

if(clicable) dropdown_lay.setOnClickListener{
   ...
}

Put it inside the onClickListener like this instead.

dropdown_lay.setOnClickListener{
     if (clicable) {
          category_recycler.layoutManager = LinearLayoutManager(this)
            ...
            ...
          clicable = false
     } else {
          set_data.clear()
            ...
            ...
          clicable = true
     } 
}
