Derma Menu Scrollbar

[Engrish Please]

For DarkRP, I am making a F1 Information Menu. It has rules on it and I have about 45 of them. In-game, it only shows 20. I tried making my derma menu and panel bigger but it still shows 20. Then I tried using verticle scroll bar but it just returns as a nil value.

Anything I can do?

[jova]

DPanelList and enable the vertical scroll bar, I think that will work.

[Engrish Please]

[lua]PropertySheet:EnableVerticalScrollbar( true )[/lua]

Doesn't work. Still returning as nil.

[Entoros]

No no, as in your content that you want to be displayed with scrollbar needs to be placed inside of a DPanelList and then set DPanelList.EnableVerticalScrollbar to true.

[Engrish Please]

So I should replace the Dpanels with Dpanellist? If not I just do vgui.Create( "DPanelList", Tabone )?

[c-unit]

What's with your tabbing?

Not quite -- in general, what I've done is made a DPanel that serves as a parent and is the one placed in each tab. Then you could add things to the DPanel, like a DPanelList or other derma objects. So add the panel to the sheet, but place objects inside the panel.
