Example:
- First user parameter is choice type with values is Provinces (Ha Noi, TP.HCM, Da Nang...)
- Secondary user parameter is also choice type with values is Districts (Hai Ba Trung, Dong Da, Ba Dinh,...)
- I select User Parameter 1 with a province and it'll filter and just show choice are districts of this province
If you know how to solve let's show me! Many thank!
