Repetitive group with fixed number of cells: keep the number of columns

Hello,

To display a set of products, I want to use the pagination.

Everything works fine on computer. However on mobile format, the responsiv only keeps the number of line displayed and not the number of column.

This means that on page 1 of my products, I have 30 products displayed on computer. But on mobile only 12 are displayed.

Is there a way to really keep the number of cells in the RG?

(it is possible by using the option : full list, but the speed of the pagination loses all its interest).

If someone has a solution I’m interested!

i want tu use the RG option : fixed number of cells
