How can I display subcollections in my product side menu?

Is there a way to display subcollections of collections in the side menu under store/products section?

Currently, in the menu when you click on Store or a sub-category of the Store like Tactical Gear it takes the visitor to the page that currently shows ALL the products in the side menu.

I would like that side menu to change to whatever primary menu item you chose and display the

If you see this website https://blue-tactical.com/collections/tactical-gear-1, under Tactical Gear in the main menu there are 7 subcategories. That is all I want to show in the side menu and then it changes if they choose another primary menu item.

Is this possible to change? Thanks in advance for your attention.

Hi @lcloer :waving_hand: , There’s no point of reference for the current sites state, only an example of another site.

Keep always in mind others do not see what you see or know what you know.
Always provide relevant context so others can understand, inspect or reproduce issues.
Context like: For theme problems always provide store url or preview urls, exact demo urls, storefront password if any, theme name, example code, are any apps involved , etc . For browser problems browser name& version, operating system, etc.

So based on parts of the loose description I have to assume some things.

Generally if theme has that feature it’s a matter or setting up menus in the admins navigation settings.

Such as the dawn theme https://theme-dawn-demo.myshopify.com/

If theme doesn’t have that feature then it’s an advanced theme customization to either enhance the theme or transplant a menu from a theme like dawn.

If you need this theme customization , contact me directly for services.
Please provide context, examples: store url, theme name, post url(s) , or any further detail.
