Hello, i'm italian... sorry for my bad english...
I have a problem that can not seem to find a valid solution. In the infobox of my wiki I entered the command <table class="collapsible collapsed" style="width:100%;"> </ table> and It doesn't appear the button show / hide and i have the necessary attributes in my wikia.css . The absurdity is that the infobox (as my css) are identical to that of its twin English and there it show work correctly in their infobox (abilities for example...) show / hide ( proving that it's not my problem appletjava), so I tried to re-edit in the box with both wiki code and the html code that the original English but with insuccess (abilità)...i used mw-collapsible and mw-collapse too... it doesn't work..... I hope someone gives light to this problem thanks!
