Show/Hide Rows & Columns Toggle Button

I was sent a spreadsheet to use as a basis for a database and whoever created it included a show/hide toggle button for various column ranges and rows.

On the attached pictures, for Row 3 there is a toggle button. Clicking the '+' button unhides Row 3, and clicking the '-' hides Row 3. I thought that was pretty useful and would like to use that on other spreadsheets, but I've searched all the menus and help files and can't find out how to add that to a spreadsheet. I went to the Macro list and there are non listed.

Any idea how to add this?

Thanks

Hi axegrynder

I think this is what you want:
Highlight the columns that you want to hide/unhide, and the go to Data > Group > Group.

Yes that's it. Thanks
