I am developing an application where I have a header and a list of lines.
The dilemma I am having is how to display an interface where the user can edit multiple lines at the same time in a user-friendly approach. The problem is that I have a number of fields (about 20) and I would like to display them all at once. This would result in horizontal scrolling (which is usually not recommended).
I am not sure which would be the best approach - whether to use this scrolling or perhaps a popup, or a section which expands etc...
I am sure I am not the first one with this problem and would like recommendations about best-practice for such a scenario.
