Posted on by Community Power Pla... Microsoft Employee

Hi,

I Have 2 fields that not connected to each other (both are a dropdown lists) and I want to have the below code:

If Datacardvalue8 = "REVENUE" than remove 1 of the options from other datacardvalue9(dropdown fields that contains 4 options but I want to show only 3 based on datacardvalue8 selection)

Picture attached - want to remove the "C_BOM" option when REVENUE is selected

 

Thanks 

Almog

    Hi @amoshe2 ,

     

    Do you want to filter a dropdown based on the content of another dropdown?

    I have made a test for your reference.

     

    1. Here is my SharePoint List.

    2. Select the Drop Down Control and apply the following formula on it Items property as:

    Choices([@DropDownTest].D1)

    3. Select another Drop Down Control and apply the following formula on it Items property as:

    Switch(Dropdown1.Selected.Value,
"REVENUE1",Filter(Choices([@DropDownTest].D2),Value<>"C_BOM1"),
"REVENUE2",Filter(Choices([@DropDownTest].D2),Value<>"C_BOM2"),
"REVENUE3",Filter(Choices([@DropDownTest].D2),Value<>"C_BOM3"),
"REVENUE4",Filter(Choices([@DropDownTest].D2),Value<>"C_BOM4"),
Choices([@DropDownTest].D2)
)

    Result:

    Hi @amoshe2 ,

     

    when this is a portal related question, you have two choices. Either

    • you create a kind of mapping (preferrable as a js-object) and attach a changhadler via jQuery to the driving listbox. When a change occurs, you hide or remove those options in the targetlistbox, which are not used also via jQuery.
    • you create a pcf that gets the input from the firstlistbox and a kind of mapping and renders itself depending on the referenced value. I am just starting with that ideas but this is, what PCF could be good for 🙂

    Does this point in the right direction or has @v-yujincui-msft already neiled it as a power app problem?

     

    Have fun,

      Christian
