Visible property controlled by GroupBy Item

Hey everyone,

I have a gallery of City, State and zip. It's put together in the gallery using GroupBy. When the user selects the "+" next to the city, state it adds all of the zip codes for the selected city,state to a collection. That collection then feeds into a textinput. Everything works great except once a selection is made i want the "+" to not be visible anymore and would like an "x" to be visible so they can delete if needed.

I've attached just this portion of the app to see if anyone can figure it out. I've been stuck on this 1 problem for over a week now. I would appreciate any help.

Thanks

Use a context variable for this. After your groupby formula in the OnSelect property of the "+" icon, put ;UpdateContext({var:false}) and set the visible property of the "+" icon to var. For your "x" icon, make its OnSelect property UpdateContext({var:true}) and make its visible property !var, that way the two icons will toggle and only 1 will be shown at any single time. You will need to show the "+" icon when you first view your gallery on the screen. So in the OnVisible property of the screen put UpdateContext({var:true})

@Drrickryp Thanks for the help. That got me pretty close but it either makes all "+" appear or all "x"s appear. I need it for just the individual items. The groupby function is in the Item section of the gallery.
GroupBy(Filter(Table1,StartsWith(city, TextInput1.Text)),"city","state_id","DATA")
Is that something I should look at changing?

Thanks again.

ThisItem.IsSelected&&var in the visible property of the "+" and ThisItem.IsSelected&&!var for the "x" icon.

@Drrickryp That works sort of as well, except it only has the "+" and "x" visible on the top item. This is the same problem I was having. It has to be something with the Groupby. I've done stuff like this before with Distinct but never had these issues. And unfortunately, I need to use the groupby function.
