Hi,
sorry for late reply, it was night for us.

The problem is your template, the select are generated by Joomla.

try to add this line at your CSS style (for example at the end of file /templates/jsn_solid_pro/css/template.css)

#jsn-page{overflow:visible;}

Sorry but I have see your css, and I not see the directive.where you have inserted?

Hi again, i am sorry for the delay.
please check my site again

Hi,
it's a very strange problem. I have investigated and I found the real problem. This is a bug of jquery.choosen built in Joomla.
remove previous CSS code and add this:

.chzn-container-single.chzn-container-single-nosearch .chzn-search{display:none;}

curiosity
before apply this patch can you try this: go on edit article on frontend and try to use select for change category of article. Same issue?
