Dynamic linked ListBox Values

I have an issue on my website. For that, I have to dynamically populate the values of the list boxes.

  1. Assume that, I have 6 list boxes. And the list box values are 11 in total.

  2. When I open any of the list boxes for the first time, it should have all list box values i.e. 11 values.

  3. I selected 4 values in 4 list boxes. List boxes have to allow you to select multiple values.

  4. When I open the 5th list box, only 7 values have to be shown to the user for selection.

Sample diagram is enclosed.

Firstly, welcome to the forums.

While we are primarily here to help people with their Free Code Camp progress, we are open to people on other paths, too. Some of what you are asking is pretty trivial in the Free Code Camp context, so you might find that if you’re not getting the instruction and material you need in your current studies, the FCC curriculum will really help you get started. At a modest guess I’d say investing a 4-5 hours working through the curriculum here will really pay off. You can find the curriculum at https://www.freecodecamp.org/learn.

With your current questions, we don’t have enough context to know what you already know or don’t know, so it is impossible to guide you without just telling you the answer (which we won’t do).

It is pretty typical on here for people to share a codepen / repl.it / jsfiddle example of what they have tried so that anyone helping has more of an idea of what help is actually helpful.

Please provide some example of what you’ve tried and I’m sure you’ll get more help.

Happy coding :slight_smile:
