From your Shopify admin dashboard, go to the "Online Store" section, and click on "Navigation".
You'll see your site's menus listed (e.g., Main Menu, Footer Menu). Decide where you'd like your store locator link to appear and click on the corresponding menu name to edit it.
To add a new menu item, click on the "Add menu item" button.
In the "Name" field, input a title for your menu link. This could be "Store Locator," "Find Us," or anything else you prefer.
In the "Search or paste a link" field, click on it to bring up a dropdown menu, then select "Pages" and choose your Store Locator page.
Click "Add" to include it in your menu.
Use the drag-and-drop feature to rearrange the menu order if needed.
Once satisfied with the positioning, click "Save Menu."
