Answer 1

I believe you want something like that :

Please follow this steps :

1- your collection should be something like the following :

ClearCollect(
    colGallery,
    {
        Title: "A",
        YesNo: false,
        ComboList: ["1","2","3"]
    },
    {
        Title: "B",
        YesNo: true,
        ComboList: ["1","2","3"]
    }
)

2- insert your gallery and update the Items property with the your collection :

Items : colGallery

3- insert in your gallery a label for the title, a checkbox and a combobox

4- Update the OnSelect property of your gallery with the following formula :

Patch(colGallery,Gallery1.Selected,{Title:ThisItem.Title,YesNo:Checkbox1.Value,ComboList:ThisItem.ComboList})

5- on both OnCheck and OnUnCheck properties of your checkbox paste the following formula :

Select(parent)

6- on your combobox OnVisible property, use the following :

ThisItem.YesNo

This should help you.
