Template with shortcut buttons for common operations
I want to create a template whereby I define a bunch of rows (for example, "bread," "fruit," "dairy") and some columns (eg "serving size," "calories," "price," "perishable").
I want the user of the template to add one or more rows nested one level under each food category, eg: "pita," "rolls," and "biscuits" as rows under "bread" and fill in the column values for each.
I know one can right-click to insert a row, then click the toolbar to indent it, but I would like an "add new item" button that would do both, and would insert a predefined row with custom validation. Eg, the "price" field has to be a number.
As a second choice, I could have a form whereby the user is prompted to add one or more items, and for each item they must select a category ('bread," "fruit," etc) and the results would populate a sheet with correct nesting.
I can write a web app to do this but wondering if possible solely using SS?
