How you interact with a board depends upon how the page builder configures it, and what types of card they add.
If permitted by the page builder, you can use the context selectors in the top-right to change the data display.
These selectors enable you to choose different values for each of a board's dimensions, which changes what data displays in cards. The page builder determines which values are available for selection.
Cards can have their own context selectors, which function independently. However, if configured by the page builder, these selectors can synchronize with choices made on the top-right selectors.
