Hello,

Could you do me a favor?

Parent Category : Yes or No

Primary Category : Look up from another list. (That is why I haven't found any solution yet)

If I chose "Yes" for the Parent Category, I want the Primary category to have some options only that have "3" in the column C(primary Category below).

So if I chose Yes, the options for the Primary Category should be G H I J. Is that possible?

Hi @happyyear ,

This is possible by applying a filter to the Items property of the ComboBox in the 'Primary Category' datacard (DataCardValue) , for instance:

Filter( DataSourceName, DataCardValueX.Selected.Value = "No" || 'Primary Category' = 3 )

DataSourceName will have to be replaced with the actual name of your datasource and DataCardValueX with the name of the combobox in the 'Parent Category' datacard.

Hello,

Thank you for your help.
I just tried to put all in the item of the datacard.
Filter( DataSourceName, DataCardValueX.Selected.Value = "No" || 'Primary Category' = 3 )
DatasourceName = my lookup list
DataCardvalueX=Parent Category : Yes or No (since it was yes or not, I put 'DatacardValue10.Value=True)
But the part below doesn't work, and nothing showed up.
'Primary Category' = 3 )
The list for look up is
If the parent category is department or (Parent category 2 is 3), the list should be displayed in the Primary category.
