I am building a software which has a lot of tablets fill out. There are situations where a table row has a lot of settings.
A consistency throughout the software is that there is an action menu on top of the table. When the user selects a row the option buttons appear. The user is also able to directly edit the table. In this case where do you believe is best to position the save/cancel buttons - above in the action menu or below the table.
Tables can have up to 10 000 entries that will load with infinite lazy scroll. Each table row can have from 1 to up to 9 options such as edit, lint, set password, lock, authorise etc
Save and Cancel buttons will be hidden until a change has been made.
Are there any articles or research in support of either of them?
