Creates an interactive clade element that is collapsible. The initial state can be collapsed (hidden) or expanded (visible). Interactivity is achieved by clicking appropriate symbols in the cladogram (e.g. ⊞ or ⊟) or custom interactive elements can be added externally with {{clade toggle}}.
This feature is intended to be used sparsely on large clagograms where the whole structure cannot be seen in the screen window.
Parameters as {{clade}} with the addition of the following:
|expanded=true– sets initial state to expanded (default: hidden)
|id=– id to control interactivity; use unique ids for independent behaviour or same ids for shared behaviour
|expand-symbol=– symbol for expansion (e.g. ⊞ --> ⊞ or ⨁ --> ⨁)
|collapse-symbol=– symbol for collapsing (e.g. ⊟ --> ⊟ or ⨂ -->⨂)
|mode=left– position of collapse symbol (left or right of the clade content; default: left)
|expand-text=(expand text)– text to replace hidden content
|collapse-text=(collapse text)– text to show with collapse symbol (when |mode=right)
Development note: The behaviour of the hidden element when in mobile mode or with javascript disable is controlled in {{clade hidden/styles.css}}. The currentl behaviour is to hide the symbols and leave the expanded content. The following CSS code can hide the content in these modes. However there are currently a couple of issues: width of labels on collapsed elements if on dummy clade; initial state of content when |expanded=true.
