Data Validation Dropdown Return Multiple Values

[JansiJansi]

Hi!

Here's what I want to do: Fill out a project plan and have a custom learning path for each client depending on their needs.

There will be sections, such as "Warehouse Setup". Each section will have a dropdown with workflow options. Depending on the option, there will be either a single or multiple links to supplementary learning videos that populate.

For "Warehouse Setup", there would be the following options, for example:
- Internal Warehouse (links to 2 documentation videos/articles)
- External Warehouse (links to 1 documentation video/article)
- General Location Schema (links to 1)
- Complex Location Schema (links to 3)

If they planned on using multiple options (ie general AND complex locations), multiple would be selected, and then a link to the documentation for each option would be displayed, like:

Data Validation Selection (2 options)	Return 1	Return 2	Return 3	Return 4
General Location Schema, Complex Location Schema	general doc 1	complex doc 1	complex doc 2	complex doc 3

I have an idea on how to do this, but I get hung up on:
1. Multiple options being selected and if this is possible (it is in Google Sheets - see this: )
2. A single value returning multiple links to documentation (I know how to do it with a single)

Thank you!
