Semantic Ui dimmer and other modules

[selloZA]

Hi Everyone
I need help with semantic ui. i am fairly new in the framework and i seem to be struggling with trying to block the section of the page while processing request. my issue is i want to show the dimmer on button click but it seems there are some clashes with jquery. long story short

$('.button).click(function() { $('ui.dimmer').dimmer('show')}) error $ dimmer is not a function.

your assistance will be greatly appreciated.
