Side Bar at the Shop Page – mobilephone presentation faulty

Hello,

using a PC and Google Chrome the Side Bar at the Shop Page works perfectly.
It is possible to use every widget and filter/ search for products.

The problem is, when it comes to mobilephone usage. The presentation is faulty.
When you click on the filter funnel it is not possible to scroll down to the last widget (if you have for example 4- 6 widgets). The last one is always not visible and as a result not clickable.
Furthermore when you have created a drop down menu an you click on it, it doesn′t open correct and mostly dissapears in seconds, so that there is no chance to select something.
Also the filter often just disappears, e.g. when you scroll down to the last widget and again down.

I know this “Mobile Chrome Version” doesn′t replace a real app, but i think this basic function should work properly and somehow it should be more or less easily to fix for the creators.

Does anyone has a clue how to solve this problem?

Thanks
