Filter menu or button help

Hi,

Can the code for the filter be embed or used as part of a menu? The mobile version is bulky and I was looking to create a button which will pull out a menu and then display the filter. (Lots of sites have this, where there’s a ‘filter’ button which then a pop up or menu shows you the filters)

Any way to do this?

Also, the button colour is this red, how can I change it? Free version, It’s the default red link colour I think, but I’d like a way to change it.

Thank you,
