Editing Template:Refbegin/doc (section)

=== Option 2: Multiple columns ===
If a value with a unit is supplied as the first parameter, i.e. {{pval|30em}}, the template will display the bibliography/references list in columns with a minimum width of that value, allowing the browser to determine the optimal number of columns.<ref>The template previously supported defining the ''quantity'' of columns rather than the ''maximum width'' of columns. For example, {{tlc|refbegin|2}} would have displayed the list in two columns. In 2023, this was deprecated. The template will treat an integer value greater than 1 in the first parameter as {{pval|30em}}, so {{tlc|refbegin|2}}, {{tlc|refbegin|4}}, and {{tlc|refbegin|30em}} all render the same as of October 2023. This is a fallback and may be removed in the future.</ref> Using {{tlx|refbegin|30em}} for instance is useful for short citations. If no parameter is specified, the default is a single column.
