That won't really work with how the filters pop-up now as it would cover the search results and be much harder to scroll through on mobile as everything would be squashed together instead of in a neat column. Only suggestion I would make for it is to allow the window to scroll from the top to the bottom of the filters without making the page itself scroll once you reach the bottom of the filter-window, which would fix what you seem to be describing.
Hey guys, Thank you for your suggestions. I would agree with tielknight that I may be better off leaving the filters off to the side for now as it is the only layout that I have been able to make kinda sorta work on all size screens. I do agree though that it is far from ideal, primarily because I suck at UI design and front-end programming, and specifically CSS. I can give the scrolling issue a shot though. What I really need to do is to hire someone to rewrite my UI from scratch, but to justify that kind of expense I first need to find a way to monetize this site (I make absolutely nothing off of it now), which requires a significant increase in traffic. So, as many times before, I am asking everyone who reads this to spread the word. As to the "by the unit" suggestion -- it is a popular one and I looked into it before, although I was not aware of the site you linked to. From the little bit of research I have done, it seems that in order to see that data in the search results one has to be logged in to Amazon, so my back-end code which interfaces with Amazon would ha ve to maintain an authenticated session, which would create issues that are too convoluted to describe here. Besides, the by the unit prices furnished by Amazon are often nonsensical (see the top result in http://www.bytheunit.com/Search?q=Bounty%20Paper%20Towel for example), so it seems that even if I put in the effort it will still not work great. I am keeping it on the list of things to look at though. Thank you once again for writing!
I don't think what tielknight is saying takes into account what you could easily achieve through responsive media queries. Quite easy to have it function differently at each screen size. I agree with pwrsrg :-P The filters at the top, not so sure they would work well being fixed position on scroll though, I think that would get in the way of the results too much. Also, I'm sure you could get someone to look at the UI as a project. Bootstrap is very easy to work with. If I get some spare time I'd be willing to have a look at it. PS. did you see my message re. UK (and other) Warehouse working again on the previous revision you made? It has been rock solid for about 2 weeks now using a cached version. Would be good to get that added back in so others can use it.
One thing is clear: UI needs work. I actually used Bootstrap when building this site, but it could probably do much more if placed in some capable hands. I re-deployed the special handling of Warehouse searches for European Amazon instances, so you should be able to Ctrl-F5 the page and see it work. And yes johnlawrence, I did get your note, will respond soon. Thank you!
