How to remove Floating Frame in LibreOffice Calc?

Hi,

Floating frame made my life easy to working in 2 parallel sheets but I didn’t get any option to close or delete that floating frame.

Please guide me.

Quite an old question, but I found it when searching for “frames”, and a little time later I also found an answer in another thread:
Open the navigator, look for OLE objects, expand it, select the item representing your frame: then you can delete it.
