You would need to put the file in the correct directory. Look at where the ones you can see are and put the one you want to see in the same place.

The output of the gate is constant. 0 Volt.

i cant seem to get it working, it wont load into the components tab. Ive put it into the correct folders. the .lib into sub and the .zip into the sym. an i doing anything wrong? or could this be outdated with the newer versions of ltspice?
It is something I found and used in 2015 so it is a bit old. However as I remember it is a plain text file more or less so you should be able to find a working file set somewhere and compare the two sets of files and find where it is going wrong.

To simulate 4000 series CMOS ICs in LTspice, download the CD4000_v.lib library, which contains subcircuit models for common gates. Include this file using a .inc CD4000_v.lib spice directive in your schematic. Ensure all gates have their VDD and GND pins connected to appropriate power sources (typically ). a c i d b o u r b o n +3
CD 4000.lib file open itself in the browser.hiw to download it… please help me.
Click on it to open it up. Then right click on the page. Then SAVE AS gives:
  CD4000.lib.txt
Edit this name to eliminate the .txt and click SAVE
Thank you sir!…
I downloaded it and pasted it. but still i am unable to acees it in LTSPICE (it is not visibble in library)
