I am using the Fresh Theme and I'm a bit perplexed that apparently the top menu bar only allows for two levels (top-level and then a sub-level, if appropriate). I appreciate that a sub-sub-level is rarely needed, but this evening I tried to create one. I can create the sub-sub-level, but it doesn't appear in the menu bar. Does the menu for Fresh Theme only allow a maximum of 2 levels to be displayed?
Fresh theme only has two levels of menu - if you need more you can use the Modern or Bootstrap theme (with a side menu) to get more.
However, another option could be to create the lower levels using a Filtered Item List or similar includelet.
For example the Website Features box on the demo site, here: https://e-voice.org.uk/demosite/
Or if you have lots of content that can be categorised, you can do somethign like the Latest section on the Superhighways site, here: https://superhighways.org.uk/latest/
Hapy to advise on how you can create an appropriate section if you give us a bit more idea what you want to achieve.
