I have noticed that the option exists in standard ModelSim versions but I have not found it in IntelFPGA versions.
May I know what version of Modelsim you are referring to where VHDL code templates are available ?
Per my knowledge there are some sample code available in Modelsim SE/ Modelsim Intel Edition stored in installation directory.
I could not understand your question, Can you please tell, where did you find that option in standard ModelSim versions.
Do you mean template available under "file -> New -> Source -> VHDL" in ModelSim Intel FPGA?

I am using version 18.0 (IntelFPGA) which corresponds to version 10.5b from Mentor.
I have checked the user's manual and I realized that in older versions (10.1) it says that you can open language templates by selecting 'Source→Show Language Templates' when the source window is open (User's Guide 10.1b page 465). However, I have not found an equivalent statement in the User's Guide for version 10.5b.
Could have this option been removed in newer versions?
Yes I checked user manual for older version Source Window language template is removed starting Modelsim Version 10.3
Modelsim User's manual page 47, "Table 1-8. Deprecated Features"
Alternatively you can make use of Verilog/ VHDL language templates provided with Quartus Prime.
Refer to user guide below on how to access them.
Topic: Using Provided HDL Templates
There are still templates for VHDL/Verilog/SystemVerilog built into QuartusII.
To use them, open a text editor window ("File/New" then select your HDL of choice) then either
(a) Right-click in the text window and select "Insert Template",
(b) Select "Edit / Insert Template" from the QuartusII menu, or
(c) Left-click on the scroll icon that is in the text editor toolbar.
These templates are for synthesis. If you want a test bench template then open your compiled project in QuartusII and select "Processing / Start / Start Test Bench Template Writer".
Hope that helps.
