Hi,
About this slider option. This slider is available only built-in possibilities like price or weight. But this i really annoying that You can't use this with other possibilities. So if you offer some items by length, then it is really good to use slider. At the moment you can use "click" type solution, but this is also annoying because filter runs automatically after every click and if there is many items then it is better to leave then scroll every time back and find another option. So is there option to put button "Run" or "Do" or something similar, then You can click on all possibilities and when you are done THEN filter is running ?
