Truncate

A truncate is a tool used to shorten numeric and non-numeric character strings, typically when the string overflows its container.

Elements

  • Content: text string to truncate
  • Position: where the text will be truncated from, ie. front, middle, or end
  • Tooltip hover: displayes full-text string
  • Ellipsis: indicates a truncate is used

Usage

Truncated items are indicated by an ellipsis (...) and are used when trying to avoud multiple lines of text or when a container is being overflowed by content. Truncation should only be used when 3 or more characters are being represented and there are still at least 4 non-truncated characters displayed. Truncated items should always incldue a tooltip on hover, showcasing the full string sequence.

  • Breadcrumbs: Use a breadcrumbs truncate when there isn’t enough room to display the entire breadcrumbs list, or as a way of managing relevance.

Behavior

A truncate indicates that the text string has been shortened, when the user hovers a mouse over the ellipsis, the full text will be displayed as a tooltip.

Variations

  • Front-line: Used at the beginning of a text string to indicate the text is being continued from a previous location.

  • Mid-line: Used to shorten a text string when the end of it can’t be truncated by an ellipsis. Also used when several text strings have the exact same middle characters, but the beginning and endings vary.

  • End-line: Used at the end of a text string to shorten the sequence and indicate that there is more content located elsewhere.

Content

  • If the text string is part of a link, the ellipsis should also be a part of the link.
  • Always include hover tooltip to display the entire string to the user.
  • Avoid abbreviations or truncated text in navigation items.
  • Truncate text within tables where the content overflows the container. Avoid truncating table headings.
  • When truncating text, aim to leave at least four characters un-truncated so the user understands what it is (for example, don’t truncate “demo1.internal-el6satelite” to “de…”).
  • Truncate long item names if necessary.
  • Avoid truncation directly before or after punctuation.
  • If a table column is resizable, the truncated text should adjust accordingly.
