AD24 allows you to sort by applying various filters. Here's how to do it.

From the AD24 homepage, select either "Bus Parts" or "Coach Parts" from the menu (top left). This will change the name of the vertical list of parts to either "Bus Parts" or "Coach Parts".

From here choose which section of parts you would like to browse through. Once you have clicked on a section (e.g. Batteries), you will be presented with a screen of all the parts under that bracket.

At the top of the screen sits a small window that looks like this.

Here you can sort between the "most relevant" and "most popular" parts, as well as choose how many results you would like to see per page.
