Module:Rail-interchange multi

This module displays multiple transclusions of {{Rail-interchange}} (or {{rint}}).

Usage

This module only takes one numbered parameter and one named parameter |div=. Each transclusion of {{rint}} is separated by a plus sign +, and there is a backslash \ between each (up to 4) parameter of each symbol. If the first parameter of an icon is the same as the first parameter of the first icon (and it takes more than one parameter) then it can be omitted.

If only two parameters are passed for a symbol, add a backslash after the second parameter (two if only one parameter is passed); otherwise, the template will not work.

One row of icons

If |div=yes then a <div> tag will be wrapped around the symbols.

{{#invoke:Rail-interchange multi|row|div=...|location1\symbol1\+location2\symbol2\+...}}

Two rows of icons (with <div> tags)

|div= does not do anything here, as the display is reliant upon using <div> tags.

{{#invoke:Rail-interchange multi|doublerow|location1\symbol1\+location2\symbol2\+location3\symbol3\+location4\symbol4\+...}}

Examples

{{#invoke:Rail-interchange multi|row|paris\m\1+\r\b+\t\3+\i\n}} (equivalent to {{rint|paris|m|1}} {{rint|paris|r|b}} {{rint|paris|t|3}} {{rint|paris|i|n}})

{{#invoke:Rail-interchange multi|doublerow|paris\m\1+\r\b+\t\3+\i\n}}
