Just goto the "Addresses" tab, find the address you want to spend from... right click and select... wait for it... "spend from"

This will autopopulate the "send" tab will all the available inputs for the selected address:

NOTE: the CTRL-click "trick" also works on the addresses tab
May be because of the lower version. I am going to update my Electrum and will edit this post.
Edit:
@HCP I realize now, it has nothing to do with the older version. The reason on the above not showing the spend from option is because the address did not have any balance that I figured. I already updated my Electrum and same thing happened when I tried with an empty address but with an address that has balance, it worked.
Thank you
