Move the skills to the item menu

[DorFenn]

Hello everyone! You see, I am creating a menu for the SaS IV (Or Saphire Action System) battle system, and the problem is that when creating the item window, these are not shown but the skill is. It is very problematic since I have tried to add the skills as an item in the categories, but I cannot get the skill to show next to the items in any way.

I put the "item.is_a?(RPG:Skill) on the category

  def include?(item)
    case @category
    when :item
      item.is_a?(RPG::Item) && !item.key_item? or item.is_a?(RPG::Weapon) or item.is_a?(RPG::Skill)
    when :key_item
      item.is_a?(RPG::Item) && item.key_item?
    else
      false
    end
  end

This is the list created, the original is after the "Else". I have the problem that it shows me only the skills.

  def make_item_list
    if skill = $game_party.members.any? { |actor| actor.skills.include?($data_skills[9]) }
    @data = $game_party.all_items.select {|item| include?(item) }
    @data = $data_skills.select {|skill| usable?(skill) }
    @data.push(nil) if include?(nil)
  else
    @data = $game_party.all_items.select {|item| include?(item) }
    @data.push(nil) if include?(nil)   
  end
end

I would greatly appreciate if you could teach me a way to display Skills and Items within the same category.

I've only made these changes to the menu, so I can't find anything else to clarify.
