Getting array of children of a class

Hi everyone!
I am, trying to make a crafting system for my game and I am trying to display all craftable items on a widget. I have a blueprint called Items that is parent of all items in the game and my question is: is there a way to get all of the items in an array without manually setting it (getting all children classes of that class). When I try using the Get Children Componens it will give me the list of children in the scene and not the actual list of items.
Thank you for your patience, I am new to Unrea!
