There is no way to order collections in Shopify without using a manually defined LinkList, which can’t be exported via API or saved in themes. It’s always admin configured.
An alternative is a method to hard code collection handles, then iterate through all collections, only pulling matching collections handles.
It may "feel" inefficient, but Shopify pages are massively cached, and a few for loops are the least of our problems. Unless we have impossibly more collections.
{% assign collection_handles = 'sport,casual,dress,bespoke' | split: "," %}
{% for collection_handle in collection_handles %}
{% for collection in collections %}
{% if collection.handle == collection_handle %}
{{ collection.title }}
thank you
very nice
