使这个函数基于表无限嵌套

Question

我终于解决了我的问题，使魔兽世界的下拉菜单的表格。

现在我需要它能够在用户提供的范围内嵌套。我该怎么做呢?

下面是我当前使用的函数:

    local info = UIDropDownMenu_CreateInfo()
    if level == 1 then
        for a,b in pairs(menuList) do
            info.text = b[1]
            info.hasArrow = b[2]
            UIDropDownMenu_AddButton(info, level)
        end
    elseif level == 2 then
        for a,b in pairs(menuList[UIDROPDOWNMENU_MENU_VALUE][3]) do
            info.text = b
            info.func = OnClick
            UIDropDownMenu_AddButton(info, level)
        end
    end

下面是使用的表格示例:

testMenuList = {Greetings = {"Greetings", true, {"hi", "hello", "good day"}}, Farewells = {"Farewells", true, {"bye", "goodbye", "later"}}}

它可以设置当前最多2个级别。第一个和子菜单。

有谁能帮我吗?

解决方案如下:

function IOLib_CreateDropDown(parent, name, title, width, anchor, posX, posY, menuList, OnClick)
    local dropDown = CreateFrame("Button", name, parent, "UIDropDownMenuTemplate")
    --_G[name].list = menuList
    dropDown.list = menuList
    -- dropDown.Func = OnClick
    dropDown:ClearAllPoints()
    dropDown:SetPoint(anchor, posY, posX)
    local function initialize(self, level)
        local info = UIDropDownMenu_CreateInfo()
        if level ~= nil then
            info = UIDropDownMenu_CreateInfo()
            info.text = title
            info.isTitle = true
            UIDropDownMenu_AddButton(info, level)
            if level == 1 then
                for a,b in pairs(menuList) do
                    info = UIDropDownMenu_CreateInfo()
                    info.text = b[1]
                    info.hasArrow = b[2]
                    info.func = OnClick
                    if info.hasArrow then _menuLists[b[1]] = b[3] end
                    UIDropDownMenu_AddButton(info, level)
                end
            elseif level > 1 then
                --print(#_menuLists[UIDROPDOWNMENU_MENU_VALUE][2])
                --for x=1, #_menuLists[UIDROPDOWNMENU_MENU_VALUE] do
                for a,b in pairs(_menuLists[UIDROPDOWNMENU_MENU_VALUE]) do
                    info = UIDropDownMenu_CreateInfo()
                    info.text = b[1]
                    info.hasArrow = b[2]
                    if info.hasArrow then _menuLists[b[1]] = b[3] end
                    info.func = OnClick
                    UIDropDownMenu_AddButton(info, level)
                end
            end

        end
    end
    UIDropDownMenu_Initialize(dropDown, initialize)
    UIDropDownMenu_SetWidth(dropDown, width) -- Use in place of dropDown:SetWidth
    UIDropDownMenu_SetButtonWidth(dropDown, width + 24)
    UIDropDownMenu_SetSelectedID(dropDown, 1)
    UIDropDownMenu_JustifyText(dropDown, "LEFT")
    return dropDown
end

下面是这个函数使用的表的例子:

testMenuList = {{"Greetings", true, {{"Hi", true, {{"H", true, {{"Amazing", false, nil}}},{"i", false, nil}}},
                                     {"Hello", false, nil}}},
                {"Farewells", true, {{"Bye", false, nil},
                                     {"Goodbye", false, nil}}},
                {"Test", false, nil}}
