Prepends and appends

Most form controls accept a

prepend and append prop that allows passing a single node/string or an array of nodes/strings. Strings will be converted into form labels and connected to the input via htmlFor for accessibility.

These are great for demarcating the input's metric like "px" or "ms". You can also pass buttons for input settings or additional filters. Just be sure to use <EuiButtonEmpty size="xs" />.
