You're able to define how many magazines per row should be displayed within a collection.
Go to "My WEBKiosks".
Then click on "Tasks" -> "Edit Design".
Go to "MY CSS Styles".
Click on "Tasks" -> "Edit".
Search for the following code within the CSS and adjust the percentage for width:
@media (min-width: 1200px) {
.col-lg-4 {
width: 25%;
}
If you don't find the code in your CSS, please copy it from above and paste it at the top.
The higher the percentage, the fewer magazines per row.
width | 20% | 25% | 50% |
