Hello client,
I understand that you would like to change the search module so that it is mandatory to fill out these two fields if not displayed a search result popup. On the other hand, it should only display a search result if the correct data has been entered in both fields. At the moment you just have to click on search and all entries will automatically be displayed.
I would love to help you bring this project to fruition! With my expertise in JavaScript/React.js, Android app development, mobile app design and development using React Native, I am confident that I can deliver an outstanding result that meets your expectations. Please let me know if you would like me to discuss further or need any additional information about my skillset or availability for this project? Thank you!
