Hello,

Choose cascading select field

Hello Alexey,

Will that work? because i just need sub-option [e1,e2,e3] under E option only?

[Alexey Matveev]

Yes, it will work exactly like this.

Thanks Alex, so i need to pick up single cascade or multiple?

How can you make the "sub-options" required if a parent is selected?
