Filtering a gallery using a dropdown

Posted on by hotdogman

Good Monday,

I want to add a filter this gallery based upon the floor levels using a dropdown as I have another filter in the gallery that only displays rooms from "RS_KS11100" on the roomsgallery items

The floors are labeled in the room names by the number at the end of "RS_11100_X"

for example,

RS_KS11100_1 is on the first floor

RS_KS11100_2 is on the second floor

then it goes up to the fifth floor

this is what it looks like right now

Perhaps you could try to set a variable OnChange of the dropdown that you can refer to in your filter code.

First, you'll either want to set the default of the dropdown to something that isn't a floor number (like "select floor" or something) OR set your floor variable to the initially shown value (in this case, 1) on App Start.

OnChange of dropdown:
Set(varFloor, "RS_KS11100_"&Text(Dropdown1.Selected.Value))

Then in your filter code, refer to the varFloor variable in the StartsWith expression where you want to filter for the floor:
StartsWith(Name, varFloor)

If I'm understanding how you're using the filter currently, I'd change it to this:
Filter(AvailableRoomEmailName, StartsWith(Name, varFloor) && Name <> "RS_KS11100_1 - Theater" && Name <> "RS_KS11100_1 - Auditorium")
If you set up the varFloor variable right, it should change to RS_KS11100_X with X being the floor selected in the dropdown box. Does that make sense/work with what you're trying to do?
