3 levels of Cascading Dropdowns example?

3 levels of Cascading Dropdowns example?

rdsdevrdsdev Posts: 2Questions: 2Answers: 0

I'm using C# .Net Core and I would like to create 3 cascading drop-downs within a row during user input (Continent-Country-State). For example:
1) Choose a Continent (which then populates the next Country drop-down from SQL Json data)
2) Choose a Country (which then populates the next State drop-down from SQL Json data)
3) Choose a State

I've seen the blog example for the normal 1 Parent to 1 Child dependent drop down. Is there an example that shows how I can use the selection from dropdown2, which will then act as a the parent for dropdown3 ?

thx

    Hi @rdsdev ,

    There isn't an example, but the blog post you referenced is the place to start. You just need an additional dependent() call, and another end-point to get the state information.

    Hope that helps,

    Cheers,

    Colin
