Check/Uncheck all checkboxes in child gallery

In my canvas app, there is a gallery with subgallery.

The gallery's Items:
GroupBy(colChecklist,"ChecklistItemGroup","GroupByTitle")

 

The child-gallery's items:

ThisItem.GroupByTitle

 

Under each parent gallery item (the grey bar below) there is a checkbox. When this checkbox is checked, I would like to check/uncheck all the checkbox in child gallery (item 1, item 2 below).

    Hi @hongkong 

    Assuming your parent gallery checkbox name is Checkbox_Parent and your child gallery checkbox name is Checkbox_Child.
    Then you can make the default property of Checkbox_Child into:

    Checkbox_Parent.Value

    So that when you check/uncheck the Checkbox_Parent, the Checkbox_Child will follow.

    You can see more info here:
