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!
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.
What is a tab in an app?
In interface design, a tab is a graphical user interface object that allows multiple documents or panels to be contained within a single window, using tabs as a navigational widget for switching between sets of documents.
