A PROD ready website developed in 100% elm

Thanks, also quick question, do you know if there is any way to show spinner/loader to show the delay during exp/col, especially on check/uncheck on search filters which filters and loads the trucks on the right side ? Also, another point, what I noticed is, the less the data that browser has to deal with, the faster the clicks responses are, so if you apply more filters and get the trucks under may be 100, then exp/col should be faster.
