1、? First, after downloading the phpcms v9 system file, put it into the local running environment and open it. Here Ozawa uses the phpstudy integrated environment as an example.

2、? The side navigation bar of a single web page has an example in the default template. If you are not familiar with tag calling, you can imitate the default template and find the default single-page template, namely page.html.

3、? Use the development tool to open the page.html file and find the side navigation bar label of a single web page.

4、? Next, you need to find your own template for the front page, that is, page_about.html Of course, the file name can be named at will, as long as it is named reasonably. This is called: page_about.

5. Then open the template page_about.html file of your own foreground single page, and then imitate the nested navigation bar labels. This navigation bar label is nested, but it is actually very simple. Just copy and paste directly.
