The only WCAG 2.0 violation that I see in here is "The file size textfields for the size are not labelled". This violates SC 1.1.1 "If non-text content is a control or accepts user input, then it has a name that describes its purpose." (Level A)

The story points are only meant for

• Set collapse / expand states to the expandable pane
• Set role=button on expandable pane
• "Search in" should be a lable for the namespace selection input box. <strong> should be replaced by <label> or maybe even a label widget
• File width and File height labels are not connected to any fields. It should lead you to at least the first drop down (e.g. "greater than"). If possible, "px" can also be added as a label to the field

I cannot find the collapse/expand state looking at the html of the beta test page. How would be the best way for me to test this ticket?
