Keep category navigation visible when scrolling down
This CSS code keeps the category navigation in view while scrolling, or to say it differently: the category navigation autoscrolls with you.

These are the steps to add personalized CSS code to the design:

1. Navigate to Settings > Layout > Designer and launch the designer
2. Click Preferences (last icon) and enable Advanced
3. Click Customize CSS (penultimate icon)
4. Add the piece of CSS code at the bottom (copy and paste)

Publish the design (first icon in the designer window) to make sure the result is live.

The CSS code to make the category navigation "fixed":

#cat {
	position: fixed;
	width: 280px;
}

Please keep in mind:

1. Manually set the width of the navigation so it fits the design.

2. If there are too many categories, some will not be visible on smaller screens because they are shown below the screen.

3. This only works on desktop; there is not enough screen space on a mobile phone to keep the categories visible.
