checkbox with combobox

[bndlyosi]

I'm looking for the user to go into a drop down list like combobox
And there will be an option to mark what he wants
Is it possible to do such a thing?

Yes, of course, and it has nothing to do with the Revit API.

Search the Internet, e.g., for drop down checkbox .net:

 I can not put it in revit
I see there is that in revit
The question is how do I do the same thing to myself

As said, it is possible in theory, as you can see.

Unfortunately, the Revit API provides no built-in support for it.

So, you can either build your own UI and hook it up with the desired Revit functionality yourself, which might be tricky, or implement an alternative solution that is supported by the Revit UI API.
