Final answer:
To skip certain items when building the navigation, you can use conditional statements in your programming code.
Step-by-step explanation:
In order to skip certain items when building the navigation, you can use conditional statements in your programming code. For example, if you are using HTML and CSS to create a navigation menu, you can add a class to the items you want to skip and then use CSS selectors to hide those items. Similarly, if you are using a programming language like JavaScript, you can use if statements to check for certain conditions and skip rendering or displaying specific navigation items.
Here is an example of how you can use CSS to skip certain items:
<style>
.skip {
display: none;
}
</style>
<ul>
<li>Item 1</li>
<li class='skip'>Item 2</li>
<li>Item 3</li>
</ul>
