If this template is used without anyparameters in the format,{{Welsh nationalism}}, the navbox displays as displayed above.
If the parameter|sidebar= is set to any value, then the template displays as a sidebar across the length of the page on its right, depending on the use of the parameters in§ Additional parameters below. This is the format to use as a sidebar at the right-hand side of an article.
{{Welsh nationalism|sidebar=yes}}
If, as in the latter case above,|sidebar= is set to any value, then the§ Additional parameters section would not apply and the visibility parameters would be ignored. If|sidebar= is not used, then these parameters function as described.
This template'sinitial visibility currently defaults toautocollapse, meaning that if there is another collapsible item on the page (anavbox, sidebar, ortable with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.
To change this template's initial visibility, the|state=parameter may be used:
{{Welsh nationalism|state=collapsed}} will show the template collapsed, i.e. hidden apart from its title bar.{{Welsh nationalism|state=expanded}} will show the template expanded, i.e. fully visible.
