How do I populate a selection element in from with Json Data

My json data has products and each of those products have categories.

I have populated this data in a repeat children element.

I want to use a select group form element to dynamically filter the products by category on the page


For that, use the data view component:
Use the JSON data source in it, and then create the repeat from the data view.

Hello again… is there any way to get the duplicates out of the dataview before binding the values. in this case I have duplicate categories. Just want it to display one… I am using JSON.

You should apply the group by filter in order to do that.
