About Linkage Function

Hi All,
In practice i want to realize a function that there is a linkage between search-boxes.
But There are no relevant examples to study in Ralph web (https://ralph-demo.allegro.tech/)
Deeply appreciate if you could take my advice.
Below is a imaginary result.
First there is a connection between ‘Manufacturer’ and ‘Software’.
When i select one of Manufacturer records,the Software categories list only views parts of values associated with the selected value of Manufacturer.
