Hello,
We have gone through your Codes. You seem to be using the .style-4 Class on the Primary Menu which is currently not supported with the Construction Demo's Menu. You will need to use the following HTML code:
[

Name of the Company](index.html)
[

](index.html)
- [Home](#)
- [What we do](#)
- [Housing Management](#)
- [Construction Planning](#)
- [Green Homes](#)
- [Architecture Design](#)
- [Interior Planning](#)
- [About Us](#)
- [Projects](#)
- [2 Columns](#)
- [3 Columns](#)
- [4 Columns](#)
- [5 Columns](#)
- [Investors](#)
- [News](#)
- [Careers](#)
- [Contact](#)
[](#)
Now, you can change the Primary Menu Item Styles accordingly.
Additionally, it is Highly Recommended that you do not Edit the style.css File or any of the Default CSS Files and instead use the css/custom.css File we have included in the Canvas 4 Package to modify and overwrite the Default Styles. This is particularly very useful when you need to Update Canvas to the Latest Version. Complete Usage Instructions regarding this can be found in the Documentation > Start > Customization Section. So, now you can add the above codes in the css/custom.css File and it should work fine.
