2 Questions fore a Skilltree

[Slayer]

I have 2 Questions about the NGUI System...

My first problem is. I have a DropDown Menue. (3 of them)
With each i would like to load a new GUI. So fore example. At the Dropdown list i have: 1, 2, 3, 4 ore more Skilltrees. (See Pieces)
I glick in the first Dropdown on Magic. Then it come the Question. "Do you want to use the Skilltree Magic?" "Yes ore not?". I press yes, so the Macig Skills GUI is activated. Now i can not more change  this Dropdown to a other Skilltree. I hope you can anderstand.

My second question: I have also test the asset from the website here with his skills, but that dosent work fore me...
So how i can do then when i aktivat Macig and it must Show me the Skills from Macig. And then i can dropable this in Hotkeyslots? And how i can aktivate the skill with click on it the Skill? And the last is. First some Skills must be Inaktiv(not usable before i have the right level), but i woud like to see it. With a mouse ouver Efeckt with Informations about the Skill.

Thank for your Help verry mutch. I have at the moment only the Dropdowns with the Names of the Skills... More i cant do

I can't understand what you wrote, so it's difficult for me to help when I can't understand you. I don't even see a question in the first part where you talk about a drop-down menu, and the second part makes no sense.

okay then again

I want to activate a other GUI with the dropdown menu. Ore better. When i want to activate some functiuns when i press on a option in the dropdown list.
Look at the pieces what i have make.
At the first piece you see the Dropdownbuttons with the Options. On this time i can click in the DropDown Menu (Ore Dropdown List) on Magic, Warrior, .....
At the second piece you see what happens when i press fore example in the DropDown Menu on Magic. Then is there a new GUI with some Skills.
Now the Question is. How  i can aktivate with the Drop Down Menu (List) the new GUI with the Skills? How can I order with the drop menu to perform?

I hope you anderstand me Ore some other Persons
The Pieces you see in my post before.

Ore? Piece? Press fore? Still doesn't make that much sense.

When any option is chosen from the popup list, its "On Change" function is triggered. You can set it on the popup list. What you do inside the function is up to you. Open another window, show some other UI element, hide something... it would be your logic. Write some code.
