Developer's manual
This is the complete Developer's manual for Ultimate Dropdown Menu Version 4.6. If you're using the menu for the first time I recommend reading the Quick start guide first.
You can also download the developer's manual in various different formats.
A note about tabbed code-examples
UDM is available in a choice of configuration languages, so many of the code examples have to show the same options in more than one syntax. To accomodate this I've come up with tabbed code blocks:
You can view each language by clicking the relevant tab at the top of each block.
