HelpMod Menu

Relatively new new to creating mod menus but i do own a few of them. I understand the concept of the menu and I even downloaded a few old source codes to get familiar with it.
I know that natives dont really change or need to be updated but the crossmaping does and also know how to link menu options with the natives and all.
But all this is from using a scripthookv with the dll, and asi file in order for it to work.

-So my question is where can I get a solid menu base
-How to update crossmaping
-And how to get the menu online?

To play online with the menu, do not use script hook v. That kicks you from an online game to prevent modding online. Don't use an .asi file in it because it will be detected when playing online. The best way to play online is to compile a .dll with the menu base and hooking and make it injectable, being as it is safer it inject rather than drag and drop into the GTA folder.

For the rest of your questions, I'm pretty sure they are on this forum. I believe if you search you'd find it. If not, Google is always your friend
