Dynamically add check boxes and apply search functionality

I have a form like below

Here T1, Windows, Sinks, etc coming dynamically from the database and I need to implement search functionality for this form. But I am not able to uniquely identify the parameter like the price included, disconnected, yes or no, etc on-page submission.
For eg I failed to identify the price included for sinks or windows. How is this possible in yii2? Please help
