I have a gallery that is correctly filtering when I have 1 or multiple things selected (things = 2 combo boxes and 1 text search box). However, I would like to have the gallery display everything when nothing is selected in the combo boxes and the text box. Basically, start with the full list of items in the gallery, and whittle it down as items/values are selected in the combo boxes and text box. The below formula starts with all blanks and brings in the appropriate values as combo box and text inputs are selected.
Gallery Items Property:
Filter('Standards, Disclaimers & Disclosures', 'Review Element(s)' in ComboBox1.SelectedItems.Result || 'Subject Matter ' in ComboBox2.SelectedItems.Result || TextInput1.Text in 'Required Language')
