Hide /Show field depending on Multiple selections done in drop down menu

Posted on by prateek2

Hi ,

Based on the multiple selection done in the drop down menu, I need to hide and show the other field in the power apps.

Eg:

Drop Down Menu has Option A ,B , C and D . The other field needs to be displayed if B is one of the selections .

I used Visible

If(DataCardValue2.Selected.Value = "B", true, false) but in this when B and C are selected , it does not work. But when C and B are selected , meaning when B is at the end then condition works. How to solve this?

@prateek2
"B" in DataCardValue2.SelectedItems
if you have just true or false, you can remove the If formula and just use "B" in DataCardValue2.Selecteditems
see if it helps @prateek2

The reason you observe it like this when "B is at the end", is that Selected.Value of a Combo Box control only returns the last selected item. So when you select B last, that's why it works only then.
So you need to check all the items as @v-dezhili-msft said, so try
"B" in DataCardValue2.SelectedItems

@prateek2 If you are using Selected.Value that one only returns the last selected item
You must use in when using SelectedItems
so
"B" in DataCardValue2.SelectedItems
not Selected.Value but SelectedItems

"B" in DataCardValue2.Selecteditems does not work. Works only When only B is selected from drop down. the moment B and C are selected , the condition fails

@prateek2 I don't think you are using a Drop down, since Drop down only allows one selection, I think it is a Combo box. Are you sure it's a Drop down? Could you provide a screenshot which control you are using?

On my side I cannot reproduce your issue, so I probably cannot help you further
@v-dezhili-msft do you have any idea why @prateek2 sees this behavior? I don't have that behavior on my side.

Yes it is a combo box only my bad. Still trying to learn.
I am using the visible condition on the other field as you stated "B" in dataCardValue2.Selected.value.
So when B and C are selected from the combo box , the other field is not visible. It is visible only when B is selected.

Do not use ~~"B" in dataCardValue2.Selected.value.~~
instead you must use "B" in DataCardValue2.SelectedItems
There is a huge difference.
Selected.Value returns the last selected item only when used in a Combo box Control.
Only SelectedItems of a Combo box Control has all the selected items.

Hi @prateek2 ,

It worked fine in my tests.
Could you please show your Items property, and the output displayed when you select dataCardValue2.SelectedItems?

Best Regards,
