Backend as to select combo

Hello,

I wondered how I could do one thing in wp .

I need to show X combo select a page , depending on the option chosen in the display select one thing or another in the next select something else … etc . That ‘s no problem.

The problem is that these select must be able to be managed from the backend of wp . So I wonder if there is some sort of plugin or something to help me this, or have I perform backend programming (to put the data in the table and select appropriate ), with the connection to the databases so the select be painted etc.

Thanks and regards.
