I am looking for a person who will make a spreadsheet template with the appearance as in the attached file on commission.
The operation of the spreadsheet:
1. when you click the green "plus" under the item e.g. 2. a row will be added with a gray background, which are the sub-items of item 2. If there was an item 3 under item 2 then the gray row will be inserted between these items.
When you click the blue "plus" e.g. at item 2, a new item will be inserted under the gray rows, i.e. 3. It is desirable that this also works in a situation where there is already an item under a given item, i.e. that you can insert an item in the middle.
