Drop down value options updating another drop down

(1) ShareShare
ReportReport
Posted on by 28

I'm currently building a canvas app and I have two combo box dropdowns  (sub_group and type_work).  I'm wanting the sub_group combo box dropdown to control the available options when I click the type_work combo box dropdown.

 

Below is the formula I entered in the "Items" field for the type_work.  When I play the app, nothings appears under I click the drop down for type_work.  Do I need to create an if statement so the options can be associated with each other.  I have 4 sub_group options and 12 type_work options

 

Filter(
    AddColumns(
        Choices('Type_Work (SCADA Activity Logs)'),
        _textChoice1,
        Text(Value)
    ),
    _textChoice1 in Distinct(
        Filter(
            AddColumns(
                'SCADA Activity Logs',
                _textChoice2,
                Text(Type_Work)
            ),
            Sub_Group = DataCardValue25.Selected.Value
        ),
        _textChoice2
    )
)

    Hi @Lander42 , These type of combo box are called cascading. PFB some resource which can help you:
