Grids are organized in columns and rows of tiles. You can achieve different designs based on the number of tiles in each row. Tiles will become smaller as you increase the number of columns to fit them all in the view.
To change the number of grid columns:
1. Click the section.
2. In the left-hand pane, look for the Column Count input field. Here you may enter a number between 1 and 30.
You can click on the eye icon next to the number on the column count to turn on/off the gridlines for your grid. The gridlines will change depending on the number of columns you have set.
