Tried different forums but don't why they closed my question
Probably for the same reason you're unlikely to get an answer here: there is nowhere near enough information to even start answering it.
The problem is that we have no idea what your code looks like; how you store data; how you display it; ... we know nothing about what you have done so far! And contrary to the firmly held belief of many beginners, there is no "one right way" to complete a development task - there are as many as there are developers doing it!
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with - we get no other context for your project.
Imagine this: you go for a drive in the country, but you have a problem with the car. You call the garage, say "it broke" and turn off your phone. How long will you be waiting before the garage arrives with the right bits and tools to fix the car given they don't know what make or model it is, who you are, what happened when it all went wrong, or even where you are?
That's what you've done here. So stop typing as little as possible and try explaining things to people who have no way to access your project!
