Query Data Selector #

Query Data Selector is a feature that allows you to easily access and manipulate data nested in product or post data. With Query Data Selector, you can use simple expressions to select, filter, and transform data from any product or post data. Whether you want to extract specific values, apply methods, or join multiple data sets, Query Data Selector can help you achieve your goals with minimal effort and maximum flexibility. After selecting and filtering the data, you can display the results on labels or images to create dynamic and interactive user interfaces.

To use Query Data Selector, you need to have a basic understanding of JSON objects and arrays.
