After you've created a shop catalog of all your products and displayed them with your preferred design, you can add a product search bar anywhere on your website. In order to create a product search bar, add a Product search+ module.
How to add
You can add a Product search+ module by clicking on the Add module option, and selecting Product search+ under the category E-commerce+ in the Add module overlay.
The Editor will automatically generate the product search bar into your catalog. After you've added the Product search+ module, you can change its alignment, background, border and spacing in the Design section.
After you've set up and appropriated the Product search+ module, your customers will be able to search your catalog based on their preferred keywords, and thus navigate through your products more easily.
