Power Apps Cascade drop down

(0) ShareShare
ReportReport
Posted on by SabariS 11

Hi All,

 

I need help in cascading dropdown. I have a SharePoint list with 2 choice columns "Country" and "State" both drop down. 

 

In power apps, I added below formula for Country drop down and it works fine,

Choices('Country List'.Country)

 

For the second drop down, I need to filter based on the country, so i tried below formula but not working,

Filter('Country List',State.Value=Dropdown1.Selected.Value)

 

the drop down not showing any error or values.

 

Thank you

    Hi @SabariS ,

    How do you know which state belongs to which country ? Does your Country list have a State column with an entry for each Country/State combination ?

    Yes, the Country List contains State column which is also a choice.

    @SabariS ,

    Yes, but how do you relate one to the other ? Choices fields are separate lists of items with no relation to each other - you need to be able to relate the State to the Country chosen. You need a list of all the States with a field for the Country they belong to.

    Hi, They are linked. They both are in same list. In "Country" column values like India, Japan etc. In same list State column values like TN, EZ and each value have corresponding country column filled.

    @SabariS ,

    If they are both choice columns, they are not linked. You be need a list with all the combinations. Do you have this ?
