[adapter]

    private val categoryItems: ArrayList<String>
): RecyclerView.Adapter<CategoryViewHolder>() {

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): CategoryViewHolder {
        val itemBinding = ItemCategoryBinding.inflate(LayoutInflater.from(parent.context), parent, false)

    }

    override fun onBindViewHolder(holder: CategoryViewHolder, position: Int) {
        holder.bind(categoryItems[position])
    }
}

[ViewHolder]

class CategoryViewHolder(
    private val binding: ItemCategoryBinding
): RecyclerView.ViewHolder(binding.root){


    fun bind(category: String){
        binding.itemTv.text = category
