What can I use instead of tabs?
If they're too long, then accordions are a better choice rather than tabs! Accordions placed on a horizontal space have too much space to accommodate long options and plenty of data, while on tabs if you choose long names as labels, they will look more or less like accordions only!
What is tab design?
The Design tab includes table formatting, cell and table borders, arranging the table on the page, and the size of the table.
When should tabs be used?
Use tabs to alternate between views within the same context, not to navigate to different areas. This is the single most important point, because staying in place while alternating views is the reason we have tabs in the first place.
