This depends on the version of your dawn theme.
I have a version 2.3.0 where this code in the “section-collection-list.css” worked:
@media screen and (min-width: 750px){
.collection-list–6-items .grid__item {
width: 16.6% !important;
}
}
I’m trying to get everything working in the new 4.0.0 version and the solution is different here:
-go to the liquid file /sections/collection-list.liquid
-scroll down to the schema part and find:
“type”: “range”,
“id”: “columns_desktop”,
“min”: 1,
“max”: 5,
“step”: 1,
“default”: 3,
“label”: “t:sections.collection-list.settings.columns_desktop.label”
-set “max” to 6 (or whatever you like)
-save and exit code
-go to customize, find collection-list, edit, move slider to “number of columns = 6”
Enjoy
