Hidable Thingy

Regular Thingy

Example:

{{CustomToggle|PRIM_TYPE|hide=Collapse|show=Expand|class=foo|collapsed=*|link={{FULLPAGENAMEE}}##}}

If the table is collapsed by default, you should provide a link (with the link parameter) to an article that contains the information in the collapsed section for users with JavaScript disabled.
