Hi! Thanks for your question.
In the Horizontal Masonry layout, there isn’t an option to manually set the number of columns. This layout is designed to build the gallery automatically in rows, so the column count is determined dynamically and cannot be defined manually.
If you’d like more control over the number of columns, we recommend using one of the following layouts: Grid, Vertical Masonry, or Justified Grid – these allow you to define a fixed number of columns. Fusion Grid – offers advanced column customization. You can: Set a fixed number of columns for all screen sizes.
Choose a responsive mode with a maximum number of columns, which scales down on smaller screens.
Enable full responsiveness where the number of columns adjusts automatically based on the screen size including support for Retina, 4K, 8K, and other high-resolution displays.
Fusion Grid provides the most flexibility if you’re targeting a wide range of devices with different screen sizes and resolutions.
Let us know if you need help choosing the best layout and modes for your gallery!
