Re: Reset Dropdown in galleryy
Hi @Gelos ,
I did a simple demo for you.
1\ This is my gallery 'Gallery1' .



2\ Insert a dropdown control 'Dropdown1' into the gallery .
Set the dropdown control 's AllowEmptySelection property to:
true
Set the dropdown control 's onchange property to:
ClearCollect(Col,ForAll(ShowColumns(Gallery1.AllItems,"Dropdown1"),Dropdown1.Selected.Value));If(CountRows(Filter(Col,Value=Dropdown1.Selected.Value,!IsBlank(Value)))>1,Reset(Dropdown1))
3\ The result is as follows:
