MakeTopTab
What it does
Creates a primary tab in a top-navigation layout.

When to use it
Use it when your window uses horizontal rather than sidebar navigation.
TabFunction:MakeTopTab(TabConfig)
local MainTabs = Window:MakeTopTab({
Name = "Main",
MultiTab = true,
OnSelect = function(tab)
print("Selected top tab:", tab.Name)
end,
})Behavior and return value
Store the returned controller or object when later code needs to update its state, call its methods, or close it.
Fields marked optional may be omitted. XLQP then uses the method’s built-in default or leaves that feature disabled.
