changed Filter if the class is a Input that the text is still selectable

[karoben]

Hello,

sry still a beginner with github.

I had the Problem that in my Sortable List I have Textboxes that I want to change. But this Textboxes are not selectable and if I add them to the filter class then they are also not changeable.

Therefore I made this change in the Filter Section.
