Thread:Extension talk:MobileFrontend/mw-collapsible not compatible with Mobilefrontend?

I am using mediawiki 1.21 and mobilefrontend.

I used mw-collapsible like

{| class="wikitable mw-collapsible mw-collapsed" style="width: 40%;" But the mobile page (both the mobile page viewed from desktop and mobile page viewed from mobile) wasn't collapsing the table.

It didn't even have the "Collapse" button.

What should I do?

I searched http://www.google.co.kr/?gws_rd=cr#fp=afad099fdd8ea46b&newwindow=1&q=mobile+%22mw-collapsible%22

but I got no answer but got some crude guess that it's related with js query thing?
