I have a dropdown that holds sections, then I add the section to temporary list and show up in gallery.

I want to add multiple sections at a time, and I am doing that however i want to avoid duplicated values, so once I add one section before I saved the gallery to other list, how can I check if the section is already added to the gallery?

Hi @IloveTigray ,

I think it would be better to validate the section before adding it to the Gallery, so the Add button would be greyed out if the selected section is already in the Gallery.

DisplayMode of Add button:

If(SectionComboBox.Selected.Section in Gallery.AllItems.SectionLabel.Text, DisplayMode.Disabled, DisplayMode.Edit)

Best regards,
