I suggest you insert a button and another check box your screen (Not inside the Gallery)
Then Option 1 (Save data whenever any of the Checkbox inside the Gallery is checked), put this formula OnCheck of the Checkbox:
Patch(YourList,ThisItem,{Model: Label1.Text, equipment :Label2.Text, Quantity: Value(Label3.Text)})
Option 2 (Check all or some of the Checkboxes before saving). On the OnSelect of the Button you inserted put:
ForAll(
RenameColumns(
BrowseGallery1.AllItems,
"ID",
"NewID"
),
If(
Checkbox1.Value,
Patch(
List,
LookUp(
List,
ID = NewID
),
{
Model: Label1.Text,
equipment :Label2.Text,
Quantity: Value(Label3.Text)
}
)
)
)
If you want all the checkboxes inside the Gallery checked at once, in the Default property of the Checkbox inside the Gallery, put CheckboxOutside.Value
Where CheckboxOutside is the name of the checkbox inserted
