The only thing I have found that works is an app called "Categories Uncomplicated" which allows you to have actual thumbnail sub-categories. (I have no affiliation with them, just helping people out).
You would think something so basic of a sub-category would be a standard feature....
If we are to create categories as collections and all the collections are on same level, when it comes to developing a private custom mobile app, how do you think we can manage categories and sub-categories if there are no levels on categories aka collections.
In mobile app it won't be easy manually have collections arranged as it would probably be using Shopify API's.
I hope you understand what I am trying to explain.
goal: for your webshop getting menu categories like men clothing women clothign and subcategories men pants men jeans men coats
whereyou can list those products under
If you want a backup of your shopify webshop for if something goes wrong
go to online store -> themes -> select the above theme "actions" -> duplicate
and beneath you get a "copy of *current webshop/theme*" that you can "publish" being a backup of your webshop
for my shopify webshop I used theme "venture"
if you want that theme go to "online store" -> themes -> explore free themes -> venture -> add to theme library
go to venture -> actions -> publish
you can always switch back to former theme
STEP 1: First you have to create the collections of the categories/subcategories you want
For this tutorial I choose the categories 1 men clothing 1.1 men pants and 2 women clothing
so those collections I create
go to "products" -> collections -> create collection
for title fill in the name of category you want like "collection men clothing" -> manual -> save
again -> create collection "collection men pants" -> manual -> save
again -> create collection "collection women clothing" -> manual -> save
now you have to create the visible menu's of the categories you want
that appear on your webshop, and link them to the collections youve created in step 1:
I choose category menu's:
Go to online store -> navigation -> main menu -> add menu item "name: men clothing" "link: men clothing -> collections -> collection men clothing "
again add menu item "name: men pants" "link: men clothing -> collections -> collection men pants"
again add menu item "name: women clothing" "link: men clothing -> collections -> collectio women clothing"
or whatever the name is of the category you want and collection youve created
because "men pants" is a subcategory of category "men clothing"
I drag the "men pants" to the right and then beneath the "men clothing" so it becomes its subcategory
then click save
STEP 3: Now go to your webshop.com
and you can see the menu's you have created
for me "men clothing" "men pants"
and "women clothing"
(NOTE: if you dont like how its structured you can change the theme in online store -> themes
changing the layout of the site
(ive chosen the "venture theme")
STEP 4: but you notice when clicking on the menu's on your webshop that nothing appears,
thats why the next step is to add products to the collections categories,
Go to -> apps -> visit the shopify app store -> search 'oberlo" click on oberlo -> add app
in oberlo go to -> find products -> *search product name of product category you want like "men pants"
-> hover over the products you want -> click add to import list
when you have the products you want go to "import list"
here you cna change the name of the products, I have selected men pants so I make sure each title contains "men pants"
-> then checkmark all and select "import all to store"
then go to shopify -> products -> search the product name like for me "pants"
checkmark all -> more actions -> add to collection -> adding it to collection "collection men pants" -> save
now the men pants you imported from oberlo,
you have added to the collection "collection men pants"
and because in step 2 you have added the collection "collection men pants"
to the menu "men pants"
now go to your webshop.com
select the menu "men pants"
and now it shows up the products youve just imported in step 4
now basically decide for yourself what categories and subcategories you want
and what products
and follow these steps again
to create your webshop with categories subcategories and there products
