You should probably give more details, and it is also a good practice to explain what you have tried. The answer to the previous post is the only way to do it if the output component is the same for all inputs (due to hard constraints by Dash). I tried it myself, and there was also a github issue about this specific thing (often pointing to solutions involving loops and hidden stuff) and another about being able to use regex patterns in callback definition (not yet closed). But maybe something was fixed in 1.0.0 and our own benevolent dictator can tell us more.
