I needed to manually close the combobox because I had an item in there that wasn't part of the options, but a link at the bottom.

Initially I had the link placed inside<ComboboxOptions>, which caused the combobox to stay open when clicked.

I moved it outside (while controlling its display with an external wrapper + theopen render prop) but clicking caused the combobox to immediately close, even before processing theclick event.

I didn't want to rely on asetTimeout hack which would be quite unreliable. I ended up patching the library withpatch-package to expose anonClose handler in render props.

I'm not a fan of carrying patches around in projects because it keeps me from confidently updating dependencies, but if you really need this, it can do the job until an official solution comes up.

Agreed! Would be nice with some access to the internal machinery to make it possible to imperatively open the combobox. My specific use case is to create a custom combobox input component (used for a very custom multi select setup) and be able to open the combobox when my custom input receives focus, just like the builtin default input component does by invoking the internal machinery.
