A perfect example would be a photographers portfolio website. They may have different pages for different types of photos such as nature, cars even maybe something small such as street signs. Having a car page would mean, no images of nature should be in the gallery of the car page, unless the photo over laps each category. Then the photo could be an exception.
Once in the navigation, you can choose between many different styles of menus. Once you choose the navigation you would like, WIX will automatically include each of your pages within the navigation bar. To place on your page, just drag and drop. Once on your page, you can fix to the whichever size you would like. Big or small, it is up to you. Also remember to place within the header of the page, as the navigation will then show on each page of your site.
However, this lack of creative control can be frustrating. Wix ADI is not nearly as flexible as Wix Editor, which offers smooth drag-and-drop design and easily editable text boxes. So, while you can enjoy simplicity with both Wix tools, the Wix Editor offers more freedom. It also builds more personal sites, thanks to its Premium plan upgrades and wide choice of apps.
First of all, you should know what your website will be about. This is the topic of your website. When starting to build a website WIX actually asks you this question, to suggest themes suitable towards your idea. You should also have an idea of what content is needed for the website. Is the website built on images, if it is a photography blog? Or/and, will you need an about page for example?
