First time posting so not sure this is in the right location. Last week my dropdowns stopped displaying the default value associated with a collection. I have verified there is data there and see other dropdowns doing the same thing. on certain list items it will display them but others it will not. I have taken a screen shot and you can see on the right there is text in the default value. This is in the view mode and if I go to edit mode nothing is displayed unless you select the dropdown then you can choose from the list.

Hi @CLSecrest，

Do you mean that you popualte the Dropdown box with data from a collection, once you go to edit mode, nothing populated within the Dropdown box, right?

Actually, it is a normal issue when you refer to different data source in a Form.

You need to retrieve the data from the data source that you used to populate the Form.

For example, I populate the Dropdown box with a field from the collection by setting Items propetry to:

Col.FieldName

Then you need to set the Default property to:

LookUp(col,Field=ThisItem.Field_In_List).Field

This is pulling the data from a gallery where I run a collection. This just started happening about 2 weeks ago I assume when the update happened. When you click on the selected item in the gallery it will not show when displaymode is set View mode or Edit mode. If you click on the dropdown in edit mode they all appear and I understand these 2 pull different dropdown items. Now the funny thing is I scroll through my gallery certain dropdowns will show but only on a select dropdown item.
