^{Originally posted by JohnHavok February 14, 2023} Hello everyone, I find myself in a situation where when using a Split Menu Button, I need to disable the primary button but not the menu associated with it. The use of a disabled on the split menu button disables all, the button and the menu. Do you know if it is possible to disable only the primary button ?

Is this a bug, enhancement, or feature request?

Feature Request

Briefly describe your proposal.

When using a Split Menu Button, it should be possible to disable the primary button but not the menu associated with it.

Which versions of Angular and Fundamental Library for Angular are affected? (If this is a feature request, use current version.)
