We can add all the ad-on extensions that can be installed after the mobile api base extension installation successful. This extension is used to show the filter options and price filter on the products list screen.
Let's look to setup the configuration
First go to the Extension module of the Navigation panel. There you can Upload and Install the priceSlider.ocmod.zip under the folder path of code & extensions / adons via the Extension/Installer menu
Once installed then go to the Extensions > Modifications menu. There click the refresh button at the top
Next go to Extension> Extension menu. Select "Modules" from the drop-down list. There you will find the “Price slider” Extension name. Click the green button to install and enable the banner product in the Edit option.
That's all! your extension is installed successfully. Hope it’s a piece of cake to do
Congrats!!! Now that your Price filter is ready, you can start selling by price filter.
